This year marks the 35th anniversary of District Energy St. Paul’s service to this great city. Within our organization, this anniversary is more than just nostalgia over old black and white photos from yesteryear. We are connected to the company’s legacy through members of our staff who were here to welcome our first heating customers and have led us through significant advancements over the years. Our employees and supporters have been essential to the incredible growth of both the heating and cooling systems, the integration of renewable heat through our biomass-fired combined heat and power (CHP) system, the start-up of large-scale solar, and our continued efforts to make our systems smarter, more efficient, and more reliable. We have 20 employees who have been with District Energy for more than 20 years. Last month at our annual Legacy Day celebration, we celebrated the service of our people, including four employees that have been with the organization for 35 years. It is such an honor to work alongside people with significant history in the industry and in Saint Paul. I know that our customers and partners appreciate the level of continuity we have had in our operations and our people.

One marker of success for District Energy and our team is the ability to take what we have learned and what is emerging in the market to make sure our system is continually improving. In our annual report and newsletters, we try to keep you updated about service improvements such as metering, access to information, efficiency best practices, and other ways we have evolved our systems and services to make sure we exceed customer expectations. As part of our efforts to optimize operations, our team is closely involved with the International District Energy Association (IDEA). Last month, members of our staff from distribution, customer service, production, and public relations joined industry cohorts in Baltimore, MD, for the annual campus energy conference, a great place for team members to gain insight into new products and technical solutions that can better serve Saint Paul customers. The conference proceedings are available on the IDEA website.

Three trends from our industry that are currently gaining momentum here in Saint Paul: low temperature loops for higher efficiency and more renewable integration, decarbonization of overall systems, and managing meter data for improved performance. District Energy is already on track to sunset coal by 2020, but we continue to see opportunities to bring other renewables into our system. Of course, Saint Paul is already ahead of the curve thanks to the biomass-derived heat from a CHP facility that uses local tree waste for fuel, but there are still great opportunities to expand and integrate new solutions. To make this integration more energy efficient and cost-effective, our team is also looking at ways to optimize distribution system operating temperatures. In the coming months, our engineering team is evaluating our production and distribution system, as well as customer buildings to update our system master plan. We will be reaching out to customers during this process to make sure their evolving building needs are included in our system improvement plans.

As spring finally emerges, our team will be kicking into high gear for seasonal maintenance, master planning, customer appreciation day, and of course, getting ready for the first pitch at the Lowertown Ballpark. We look forward to seeing you all out and about as winter finally subsides. As always, don’t hesitate to contact our team with your questions and inquiries. We are here for you.

The 428 is Bringing WELL to Downtown Saint Paul

The 428 renderingWhile many people will remember enjoying a soda or slice of pie at the F. W. Woolworth Co. lunch counter, few will recognize the building after its astounding renovation. Design elements in The 428 will honor the building’s former life through repurposed materials and a mid-century modern design, however, the building has been transformed into an inspiring, up-scale, and sustainable office space featuring wellness-focused amenities. The 428 offers a range of working spaces for individuals and organizations, including a co-working space with a roof-top patio called “Wellworth.” Our team at District Energy is thrilled to see this mix of innovation and sustainability added to downtown and our system.

In addition to Class A office space, The 428 will offer occupants innovative support for their health and wellness by following the International WELL Building Institute’s WELL Building Standards. Recognizing that we spend a majority of our time indoors, the WELL Building Standards are designed to make buildings and interior spaces healthy and nourishing for the body and mind by attending to seven concepts: air, water, light, fitness, comfort, mind, and nutrition. To improve the interior environment, The 428 will avoid VOCs in building materials, filter air and water, and manage natural light. Connecting to District Energy contributes to WELL standards by providing heat from renewable energy and helping to avoid refrigerants. The 428 is on track to be Minnesota’s first building to receive both LEED Silver certification and WELL Building Core and Shell certification.

The 428 renderingThe 428 renovation responds to workplace trends for co-working and wellness. Pat Wolf is the president of Commercial Real Estate Services that is developing the building, and she said, “Employee wellness is shifting focus to how businesses can create environments proven to make employees healthier and more productive, helping recruit and retain the best talent. We’re partnering with organizations to provide a firm foundation for health and sustainability for their staff and business.” Pat also serves on the Board of Directors for District Energy St. Paul.

District Energy is providing heating, domestic hot water, cooling, and snow melt to The 428. As long-term partners with Commercial Real Estate Services, we were eager to match our environmental values with their vision for the building. Pat said, “Our team has partnered with District Energy on three buildings, and we have all come to depend on the reliability of the system and the people. Working through LEED and WELL Building with them has taken our partnership to the next level.”

Building Piping Solution – Polypropylene

Our team monitors product and process developments that could benefit our customers and our system. Over the last few years, more options for piping products have come into the market, both for use in a primary system distribution, as well as the customer building-side hydronic loop. Our team has closely monitored and tested the new products including polypropylene-random (PP-R) and second generation polypropylene-random crystallinity temperature (PP-RCT). Several companies in the US and abroad offer products made from these compounds including Aquatherm, Niron, and ISCO.

AquathermWhile a few of our customers have installed these products, this winter The 428 building project installed Aquatherm for their entire building-side heating and cooling system. While Aquatherm has been developing products for three decades, Aquatherm’s blue pipe was introduced to the market in 2003. It is a rigid thermoplastic pipe that comes in a variety of sizes and can be substituted for pipes made from other plastics, copper, and steel. This pipe can be used in applications with temperatures from -5° F to 200° F based on pressure rating. The temperature and pressure ratings of the pipe make it a good solution for customer buildings on our system.

Features of polypropylene pipe include:

  • The chemical compound is hydrophobic, inert, VOC-free, and resistant to chemicals. This means that there are no biologicals, pipe corrosion, or chemicals leaching into the water flowing through the pipe or leaching from outside the pipe into the building system.
  • Since the pipe will not corrode, chemicals can be reduced for water treatment. However, water treatment is still required to protect heat exchangers and coils from fouling, scaling, and plugging.
  • The absence of pipe corrosion and scaling can reduce the electrical demand for pumps over the life of the system.
  • Pipes are non-conductive and do not require a dielectric separation or anode bag installation that metal pipes require.
  • Pipe connections are heat fused creating one pipe and eliminating joints as well as glues or sealants.
  • The material is heat resistant and has limited expansion and contraction, performing similar to copper in this regard.
  • Pipes can be expected to last 60 years or more and can be recycled in most places depending on regulations.
    Installation can be performed by a trained pipefitter.

AquathermPolypropylene pipe has some qualities that should be considered before it is selected for a project. While the material is lighter than metal pipe, it is more flexible, so it requires structural supports to be spaced more frequently. The width of the pipe wall is larger than steel and therefore may require increased pipe sizing depending on the application. Polypropylene pipe does not offer a solution for high temperature/high pressure applications.

Our construction superintendent, Jason Klinkner, has become one of our resident experts on piping products. Jason suggests that, “The 428 project was a good scenario to use Aquatherm for an internal building service. Not only does it have a significant warranty that is comforting to our customers, but it is also resilient to a wide variety of issues which makes it a great application.”

Aquatherm was developed in Germany and has a manufacturing and distribution location in Lindon, Utah. If you have a building project in your future and would like to learn more about polypropylene options, our team would be happy to help answer your questions info@districtenergy.com

An important part of providing value to our customers is monitoring the trends in our industry and across various market segments. My observation is that there is one consistent, underlying theme: the changing needs and expectations of customers. With access to volumes of information on their increasingly smart and internet-connected devices, customers are expecting more. They are leveraging their access to information and new tools and insights to take more control over their decisions.

As the energy systems built by our grandparents are being transformed to more responsive and personalized networks, the expectations of energy consumers are also changing. When District Energy St. Paul started 35 years ago our customer buildings did not have an automated building management systems. Today a majority of our customers use digital and even cloud-based building automation and management tools. Systems that put a wealth of real-time data at the fingertips of operators and owners. This data can be insightful, but it can also be a bit overwhelming to turn this data into information that can drive better system performance.

We know that an increasing percentage of our customers want to be on top of their energy usage, so they can use less and save money. This frequently means sifting through multiple data points to find answers. Working with our customers directly, we have seen many approaches to this analysis, and we have helped to identify specific solutions to make equipment and systems run more efficiently and effectively. This year we completed a multi-year effort to upgrade all customer primary meters to 1-minute data, and we are able to rapidly access the data on those meters. This investment is enabling us to help customers troubleshoot underperforming building systems and tune the performance to increase efficiency. District Energy customers can also integrate outputs from our meter directly into our customer’s building management system to analyze and control their energy use. As we continue to test and integrate new technologies, we are focusing on solutions that are reliable and cost-effective for our customers.

If you would like to learn more about integrating District Energy meter data into your system, or if you have a question about the tools available to you, please contact our customer service team at 651.297.8955.

333 on the Park
Last spring, new residents were welcomed home to 333 on the Park. District Energy was happy to welcome this beautiful apartment building as the 41st residential building on our system, providing it with cooling, heating, and domestic hot water.

333 on the ParkA historic renovation, the building has been transformed into a 134-unit luxury apartment complex situated in the heart of the Artist District between Mears Park and the Union Depot. 333 on the Park offers studio, 1, 2, 3-bedroom, and penthouse apartments with high-end finishes. A few of the building amenities including a yoga studio, concierge, 24-hour fitness center, artist gallery, sky lounge, large community room, underground parking, and of course district heating and cooling. District Energy services are new to many of the tenants. From the sounds of it, they are quite pleased. Calsey Smith, Community Manager for 333 on the Park says, “The bills don’t lie. The residents are happy to see their utility bills much lower than the other properties that they have lived in previously.” The building operators and managers were also new to the system. They are extremely grateful for the outstanding customer support District Energy has provided during this learning period. “All of our questions and concerns are always answered immediately. Customer service is always quick to walk us through an issue or come on site to show us how,” stated Calsey.

333 on the Park was formerly known as The Gordon & Ferguson building. Constructed in 1913 and designed by Clarence H. Johnston Sr., a prominent Saint Paul architect. It was the original headquarters for entrepreneurs Richard Gordon and Paul Ferguson who dealt in hats. Their business grew to become the outdoor clothing line under the brands Field & Stream and Town & Country.

Conveniently located in Lowertown, there are still a few of these gorgeous apartments available with outstanding views of the Mississippi River – be sure to schedule a tour today.

Ask the Engineer – Getting the Most out of Your Building Automation System Part 2
This is the second of two articles that focused on your building automation system. In this article, we will share some suggestions on using warnings to monitor system conditions. By taking some time to set up warnings on control points, you can use real-time building automation system information to identify which piece of equipment requires the attention of building operators before the issues turn into occupant complaints.

Alarms are a very common part of any automation system. They are used to tell building operators when things are too hot, too cold, when the command of an object does not match the status of the object, and many other conditions. What alarms will not do is allow operators to see when things are not properly controlling before they get outside of the allowable operating parameters. Setting up warnings on control points fills this gap.

Warnings are best used on analog outputs like damper commands, valve commands, pumps and fan speed outputs, as well as, PID loop values like cooling demands, heating demands, or static pressure resets. Warnings do not work for two-position equipment that require the control device to be on or off, nor will it work for equipment in series where one device is supposed to completely open before a second device starts to open. One example of this could be a 1/3 valve 2/3 valve operation.

Warnings can be setup in many ways but one common way is to add a warning to a point that is at 100% of its control range. In an effort to maintain control, the point has gone to its extreme position and is, or will likely soon be, letting the control variable drift out of the correct range. Examples of this would be a radiation valve that is 100% open but the room temperature continues to drop or a VAV-box that is providing 100% of the design air flow but the temperature is still increasing in the space. Figure 1 shows a VAV box that is 100% open but is shy of its design air flow by 30%.

VAV with reduced airflow

Catching issues like this will help to prevent uncomfortable indoor conditions and reduce excess energy usage before they become major failures. In this reduced air flow example, the issue could be related to a reheat coil that has become coated with dust and debris and is no longer allowing enough air through the coil or it could be play or slack in the damper linkage. Regardless of the issue, a physical examination of the equipment is the only way to determine the problem.

Setting up warnings on your building automation system is another tool that building operators can use to monitor and manage building equipment. In the first article, we shared some suggestions on using totalizers to verify equipment run time and using pressure independent valves to monitor energy. If you have questions about energy savings opportunities or your District Energy connection, please contact the customer service team at 651.297.8955 or info@districtenergy.com.

Cyber Security
Cyber security is a significant priority for most companies these days, as the general security environment is changing on a nearly constant basis. At District Energy, we recognize that security is a core element of our system reliability, and therefore we have put substantial effort into developing our security program over the years. The program is based on industry standards with necessary customization for the needs of our business and systems.

Our security program touches all levels of our information infrastructure including network systems, policies, monitoring protocols, staff training, and ongoing communication. Business networks and industrial controls systems require different methods to secure them and our program addresses these differences. Our team also has the ability to tailor security measures between operating sites, as needed, to meet unique security requirements. Our company’s leadership is committed to making cyber security a top priority on an ongoing basis, evolving to respond to an ever-changing environment while making sure that we continue to provide reliable services to our customers.

Saint Paul Building Engineers Attend Seminar
Operating Engineers SeminarIn early November we hosted engineers from our customer buildings for the annual Operating Engineers Seminar. Engineers Jeff Volovsek and Bob Ford presented information and solutions to help customers save energy as well as how to incorporate recent code changes for heat recovery and the best practices for process cooling. Tom Thomalla, Senior Information Technology Manager, also shared an overview of the cyber security initiatives at District Energy. This event was a great opportunity to connect with building operators. The presentation from the event is available here. Thank you to all who attended.

If you have questions about these topics or your District Energy interface, you can contact Jeff and Bob for assistance by calling 651.297.8955.

District Energy’s A- Bond Rating Confirmed by Standard and Poor’s
At District Energy we have focused on our operational process to manage our assets and to follow sound financial practices, because our financial strength directly impacts our customers and our system. This priority has helped us to keep our rates steady, while continuing to make investments in system upgrades.

This past month, our team was able to validate our approach to financial stewardship by affirming the A-/Stable rating we received in 2013 from Standard & Poor’s (S&P). S&P affirmed its long-term rating of A-/Stable for the 2017 Series 2017-3, 2017-4, (Taxable) Series 2017, Cooling Series 2013 A-E and Heating Series 2013-A-E revenue bonds.

The rating review reflects a series of credit strengths, including stable revenue under long-term contracts with a fairly diverse customer base, cost base rates that are adjusted annually to fully recover costs (including debt service) and an energy charge that can be adjusted monthly if necessary to recover changes in the cost of fuels, and well-managed assets, which are reliable and competitively priced. The A- rating is significant within the utility industry. Investment grade ratings of BBB- or above are seen as a major threshold for business stability and financial continuity.

The end of summer has always been one of my favorite times of the year. We are usually nearing the completion of major summer construction projects and the important offseason maintenance work in the plant. The heat of summer begins to wane, but we are still enjoying great evenings of baseball at CHS Field and dinner on the great Saint Paul patios. This year, the seasonal transition has also been punctuated by exciting changes with some of our partners. As a Saint Paul Area Chamber of Commerce board member, I was thrilled to welcome Brenda Kyle to the organization as the new President. We have had the privilege of collaborating with B during her time with the Saint Paul Port Authority, another stellar partner, and we are excited for this new chapter for her and the organization.

In addition to the aforementioned partnerships, our team looks at our work with our customers as a partnership. We work together to find ways to save energy and money and operate systems more effectively. And some may not realize that our primary systems actually integrate with customer systems to help supplement our primary production and continue our strong history of reliability, while still helping the system be cost-effective and flexible to needs. Regions Hospital has long been a valued partner who uses their central heating and cooling plant as a resource to support the reliability of the heating and cooling systems.

Saint Paul Saints 3C

Saint Paul Saints 3C Club

We are also excited to share the news from two of our customers that specialize in fun in Saint Paul. First, we are looking forward to sponsoring a new endeavor by the St. Paul Saints. The Saints are bringing together their partners, corporate sponsors, season ticket holders, and fans to converse, connect, and build community. The 3 C’s Club will offer event guests the opportunity to network and hear from unique speakers that will share their experiences through jokes and stories. At the first gathering in June, we met many new people that we look forward to getting to know better.

In this newsletter, you can learn more about the newly renovated Minnesota Children’s Museum. The Museum recently reopened after an innovative remodel that focuses on play. We could not be happier for the great reception the changes have received from the community.

Thank you to all of our partners for the ways that you help us to continually improve our service to grow our system together with our community.

Minnesota Children’s Museum Reimagined

Kids and adults are loving the reimagined Minnesota Children’s Museum since it reopened in June. After an extensive renovation to the building and exhibits, everything is new. District Energy has provided cooling to the museum since it opened in Saint Paul in 1995, and the remodel provided the perfect opportunity to expand our services to include heating and domestic hot water. We are excited to be part of the inspiring transformation of this regional destination.

The remodel is the museum’s first extensive overhaul of exhibits and the building since they moved to the Saint Paul location. The exhibits were redesigned with the philosophy that open-ended activities give children the space and freedom to explore, putting children and their imaginations in the driver’s seat. Activities without directions or predetermined outcomes encourage kids to figure things out for themselves as they experiment, tinker, and work together. Beyond the joy of free play, the goal is to help kids develop lifelong skills such as creative thinking, confidence, collaboration, and critical thinking.

“We’ve created a bigger, better, and bolder children’s museum,” said Dianne Krizan, president of Minnesota Children’s Museum. “Families will find ways to play, explore and learn together like never before.” There are 10 all-new exhibits that appeal to children from 6 months to tweens. Most of the exhibits have special areas called “Tot Spots” especially for younger children. A couple of highlights include The Scramble — a 4-story climbing adventure with a 2-story slide, The Studio — a maker space with real tools and authentic materials, and Super Awesome Adventures, which includes a green-screen climbing wall, laser maze, and carpet skate park. Plus there are two outdoor galleries that are open seasonally.

As soon as you step through the museum entrance, it is clear that kids love the new space. Adults will love it too. During the remodel the museum increased visitor space by 35%, added more restrooms, as well as a café with coffee bar, improved flow and sightlines throughout the museum, and added an entrance on the skyway level.

At District Energy we congratulate the museum on their exciting redesign. We are proud to take the worry out of energy production, so that the team at the museum can focus on their visitors having fun. In addition to museum’s great exhibits, the museum hosts a variety of activities and events including birthday parties, a 21+ event called “Adults @ Play” on September 28, and Halloween parties on Sunday, October 29 and Monday, October 30.

 

 

Ask the Engineer – Getting the Most out of Your Building Automation System

This is the first of two articles that will focus on your building automation system. In this article, we will share some suggestions on using totalizers to verify equipment run time and using pressure independent valves to monitor energy. Building automation can help building engineers monitor, integrate, and control building systems from air handling units to lighting. By taking some time to set up some operational parameters, you can gain insight beyond past trends and failure alarms to identify problems in system function. Many control points or objects have built in features that take a few steps to enable.

The cheapest and easiest way to save energy is to simply turn off equipment when it does not need to run. A basic step in setting up a building’s automation system is to establish a schedule. Scheduling generally reflects building occupancy and tells equipment when to turn on and off to accommodate the needs of the people in the building. With a schedule in place, you can set up a simple cross-check to make sure that all the equipment is running for the desired amount of time per the schedule by enabling the totalization property on both the schedule object and the equipment status. The totalization property counts all the time that a piece of equipment is running or the hours that the schedule is occupied. By checking the equipment runtime each week against the appropriate schedule it will be apparent if the equipment did not run long enough, ran too long, or may not have shutdown at all. This simple check will help to ensure that you are optimizing the amount of energy your building is saving.

Figure 1 below shows a sample of the programming that includes point totalization, resets, and the value before reset properties of each points. This example shows a fan that ran 22 extra hours above its schedule, which in this case is 35% longer than it was supposed to. Not only does this represent additional fan energy, but it can also represent running cooling or heating pumps longer, conditioning more outside air, and increasing equipment maintenance and repair.

 

Runtime BMS Calculations

Figure 1: Runtime BMS Calculations

 

If you have ever wondered if different pieces of equipment run with the same efficiencies or which parts of your building take more energy to provide the same comfort, then installing pressure independent valves and/or energy valves may be a low-cost option to provide some proportional insight into energy saving opportunities. In order to calculate energy usage, you need two things: fluid flow rate and the differential temperature before and after the device. These types of control valves by design allow for precise control for consistent water flow at air handling units, fan coils, and other hydronic devices. Temperature sensors and a well to install them can cost between $50-$100 plus the labor to install them. A good time to install pressure independent valves is when you are replacing existing valves or at the time of new project or major remodel. With these devices, the building automation system can be used to calculate, trend, and totalize the energy being used from each piece of equipment. Weekly or monthly comparisons can be made between different devices as well as the history of the same device to identify when equipment may be using excess energy. This could help to identify issues like plugging or coating coils, failed dampers, and equipment that is taking energy even though its associated fan or pump is supposed to be turned off.

By enabling your totalization settings and adding pressure independent valves, you can enhance your building automation system to gain a better understanding of your building’s actual energy use. In addition to saving money on energy, these tools can help you to identify equipment issues. If you have questions about energy savings opportunities or your District Energy connection, please contact the customer service team at 651.297.8955 or info@districtenergy.com.

Ask the Engineer – Efficiency Gains with Cooling Start Up

It is the time of year when customers have already switched on the air conditioning in their buildings. As we look toward the warmest days of summer, our engineers would like to offer some strategies to optimize your cooling systems. A few key activities can help manage monthly cooling demand. These efforts include starting equipment at minimum speed and ramping up to operating conditions, staging individual equipment start up schedules, and tuning flow control.

There are several measures that can be taken to stage equipment start up, including staggering when units are scheduled to start and limiting their output with a ramp function. Ideally, your peak cooling demand should occur during peak cooling conditions, following the weather patterns and occurring in late afternoon when the outside air and building are at their warmest. When controls are not programmed to stage equipment start-up, a false demand peak can be set first thing in the morning when equipment comes online. There are a couple of ways to stagger equipment. First, if air handlers and pumps are powered by a VFD, change the programming so that this equipment starts at minimum speed. This will allow the air and water systems to move less fluid around the system limiting the output of each device when temperatures are the farthest away from the normal operating condition. Once a control valve for a loop has been able to control the leaving fluid temperature to its respective set point, then the pump or fan can ramp up its speed slowly over 30 to 60 minutes depending on the size of the system, slowly bringing the building temperature down without setting a morning peak. If you have only a few large air handling systems, staggering the start by 15 to 30 minutes will further reduce the chances of setting a peak at startup.

flow control graphAnother method for managing monthly cooling demand is to tune flow control. A hunting control valve will generate times of peak load followed by almost no load. By improving the flow control on the valve, a more steady demand can be achieve avoiding high peaks, and it is easier on equipment keeping the pumps, valves, and motors at constant operation. The graph to the left shows a building that only needs to average 70 tons an hour but peaks at 180 tons for 5 minutes and then drops off to 5 tons for 5 minutes. This variation between too much cooling and then too little cooling impacts building occupants. For optimal thermal comfort slow transitions should be made to eliminate these variations.

If you have questions about implementing these measures in your building, or if you would like additional assistance to get the most from your District Energy cooling connection, please contact our team at 651.297.8955 or info@districtenergy.com.

Celebrating Ground Breaking at the Treasure Island Center

Treasure Island Center eventOn the sunny afternoon of April 11, the District Energy team gathered with other Saint Paul stakeholders at the newly named Treasure Island Center to celebrate the project’s ground breaking. District Energy is proud to provide heating, domestic hot water, and cooling to the facility. We have been working with the Port Authority and their development team to create a customized solution that will provide the best service to the building and the new tenants.

The most unique feature of the redevelopment will be the NHL-quality ice rink located on the top floor of the facility. Instead of using an external cooling tower, District Energy chilled water will be used as a source for heat rejection for the chiller that will keep the ice hockey ready. The rink will serve as a practice facility for the Minnesota Wild as well college and amateur teams, camps and classes, and community groups.

Additional building tenants include TRIA Orthopaedic, Walgreens, Minnesota Housing Finance Agency, Stacked Deck Brewing, and Tim Horton’s. The building is scheduled to open this fall. Congratulations to the Saint Paul Port Authority and Hempel Companies as well as all of the sponsors and tenants for reaching this significant milestone.

New customer: 333 on the Park

333 on the Park eventDistrict Energy welcomes its newest heating and cooling customer 333 on the Park, a high-end apartment building adjacent to Mears Park in Lowertown. On March 23 the building hosted guests for a grand opening.

District Energy: Energy Efficiency through System Optimization

Customers on a district energy system benefit from the efficiencies of district energy’s flexible and adaptive technology. The district energy approach leverages thermal storage, aggregates customer loads to achieve more efficient heating and cooling production, and integrates multiple heat sources, helping the system be more reliable, efficient, and reach a better environmental profile. District systems make utilizing low-grade energy like solar thermal more economical on a large-scale basis. Buildings in downtown Saint Paul have diverse energy needs, for example commercial office buildings require heating and domestic hot water during the day while residential buildings have a higher demand in the evening. This type of load diversity pairs very well with district energy systems that can flex to each demand with our fleet of energy production equipment. Optimizing the available equipment to the seasonal and daily peaks at a district system level, improves overall efficiency in the system, which reduces costs to customers and lowers the energy footprint for all buildings and users.

At District Energy our engineers have an in-depth knowledge of how our system performs best with each building and they work closely with building operators to achieve higher efficiency and reliability. Our engineers can help our customers get the most out of their District Energy connection by providing operational and maintenance knowledge including advice on building equipment upgrades, control optimization, and aligning daily plant operation with the system needs. For current customers, we can help you refine your system to get the most out of the original design of the District Energy interface and improve efficiency. For new customers, our engineers will work side-by-side with your architects and engineering staff to make sure the mechanical interface is right for your building’s needs and helps you run efficiently, reliably, and cost-effectively.

If you are interested in speaking with one of our engineers, please contact Customer Service at 651.297.8955.

I started my professional career as an electrical engineer designing infrastructure projects. The work was challenging and rewarding as I worked on complex projects around the globe. While I enjoyed solving technical challenges, what motivated me the most was collaborating with my talented colleagues to deliver exceptional results.

The people side of the business is what continues to motivate me today. With the busy holiday season upon us, I want to pause in consideration of the people that make this work so rewarding and who help us to be successful in our mission. I want to say thank you to our customers, our partners, and our team.

To the people that we serve, our customers, thank you for continuing to put your trust in us to provide you with reliable heating and cooling services. District energy works best when the buildings and the energy system that serves them are working together.

If you have questions about your District Energy mechanical interface, you can contact Jeff and Bob for assistance by calling 651.297.8955.

The presentation from the event is available here. The seminar discussion has spurred more ideas for future training. If you attended, there is still time to fill out the event survey, which will influence our customer programming. Thank you to all who attended.

SciGirls Visit the RiverCentre Solar Installation

SciGirlsA group of 15 members of SciGirls spent the day learning about energy with us on October 11. SciGirls is an educational group that reinforces science skills for middle school girls (ages 9-13) and introduces them to STEM opportunities. The girls started their day by learning about wind farms and then designing and building their own wind demonstration projects out of office supplies. After the students presented their projects to the group, our own Nina Axelson introduced them to the concepts of district energy, biomass-fired combined heat and power, and solar thermal technology. We had a little help with our lesson thanks to this great video we produced in partnership with the Saint Paul Saints. The SciGirls had a great time going on the roof of the RiverCentre to see the solar installation close up. It was fun to host this vibrant group of girls who are so excited about energy. Read more about the day on the SciGirls blog.



District Energy: Making Energy Easy for Our Customers

Over the next few newsletters, we would like to help connect you to more information about your district energy service connection and what benefits it provides to your building, your tenants, and your stakeholders. This month we will start with some community benefits and the advantages of eliminating on-site energy production.

District energy is a globally recognized approach to saving energy, reducing carbon emissions, and for creating opportunities to integrate renewables into smart thermal and electric grids. Buildings connected to district energy networks benefit from decreased capital investments for individual building production equipment, decreased maintenance, decreased stress on valuable building space, and ease of use for operations and permitting.

mechanical-room-piping-webDistrict energy systems deliver thermal energy through steam, hot water, or chilled water that can be used for heating or cooling space and equipment, domestic hot water, and process heating and cooling. By connecting buildings together, customers can eliminate their on-site equipment, including boilers, hot water heaters, and chillers, as well as cooling towers and smokestacks. By reducing energy production assets, customers reduce their up-front capital costs for equipment as well as ongoing maintenance tasks and expenses. If you have five buildings that get their domestic hot water from a district energy system, you have eliminated five individual water heaters that require inspection, repair, and replacement.

District energy customers are relieved of the burden of energy production, which is now managed by the district energy operations team that monitors production 24 hours a day, 365 days a year. Additionally, operating the building-side mechanical equipment and controls are simpler than on-site energy production. While the building-side mechanical equipment is sized relative to the building’s needs, it tracust-mechanical-webditionally requires less square footage than energy production equipment. This means district energy customers can utilize more of their real estate for their primary mission. District energy networks are also more reliable than stand-alone building systems that rely on limited equipment assets. Customers that receive energy from a district energy system also eliminate the need for on-site fuel delivery, on-site combustion, cooling towers, smokestacks, and required licensing and permitting.

A district energy system can more easily integrate new fuels and new technology than on-site equipment. When you purchase on-site equipment you are married to the fuel and technology for the life of the equipment. A district system can integrate renewable fuel or energy like biomass, waste heat, and solar. District systems frequently integrate thermal storage that acts like a large-scale battery, which would not be practical for individual buildings. When paired with renewable energy sources and efficient technologies, such as combined heat and power, district energy becomes a key approach to increase energy efficiency and reduce carbon in our communities.

15th Annual Intercity Leadership Visit – Baltimore, Maryland

In October, 95 civic and business leaders from Minneapolis and Saint Paul, and surrounding suburbs, traveled to Baltimore, Maryland, for the 15th Annual Intercity Leadership Visit. The Minneapolis and Saint Paul Chambers of Commerce host this annual trip to study challenges in other urban centers.  Last year the group traveled to Seattle and previous study trips have included San Francisco, Denver, Portland, Austin, Charlotte, Atlanta, Toronto, San Diego, and Boston.

This visit was particularly important as the delegation examined the effects of institutional racism on the communities of Baltimore. Clearly the impacts have been far-reaching, particularly after the Freddie Grey incident that caused so much unrest in the city. The delegation met with leaders from across the city, representing health care, education, housing, economic development, and other sectors. One of the most commonly cited challenges was access to transportation, which disconnected people from available jobs. There is clearly a lot on the line in Baltimore as the city and its partners work to rebuild infrastructure and make investments into helping communities and the next generation, and there was much to consider for how these lessons could be considered in Minnesota.

District Energy St. Paul has been participating in the ICLV program for several years, joining others from the region interested in fundamental civic topics. We have also participated to learn from other utilities and leaders about saving energy, reducing energy costs, and improving the environmental profile of operations. It also gives us the opportunity to better understand how policies and partnerships are delivering economic growth, increasing opportunities for diversity in the workforce, and making the right investments into local education, among other important matters in other regions. Each time we have visited a new city, we have taken lessons back to help our organization and strengthened regional relationships that enable us to with partners to better our city and our region. Special thanks to the trip organizers, sponsors, and the Minneapolis and Saint Paul Chambers for making this trip possible.

As the summer of 2016 comes to a close, our team is completing our maintenance and upgrade projects in preparation for the heating season. Such infrastructure investments are critical to providing the reliable heating and cooling services District Energy’s customers expect and, in many instances, need to achieve their mission. We have also been investing in new tools that help us further optimize our system performance and provide better information to our customers. Over the last year, our team’s work on increasing heating and cooling efficiencies have meant that we are getting even more energy out of our fuel and electricity inputs. Since we pass the savings gains onto our customers, increasing system efficiencies results in lower energy rates for our heating and cooling customers. Currently District Energy’s customers are paying lower energy rates for both heating and cooling than we forecasted at the beginning of last year.

Over the last two years we have tested and implemented strategies to further optimize the operation of our chillers, cooling towers, and two chilled water storage tanks. This effort resulted in reducing our electricity costs, enabling us to lower the energy rate charged to our customers. We have done this without compromising our reliability. We have also worked closely with our customers to increase the Delta T performance of the HVAC systems in their buildings. Delta T measures how effectively and efficiently a building’s HVAC system is performing. Increasing Delta T is one of the ways customers can greatly improve efficiency and reduce their costs. Additional system improvement projects have focused on data communications, including a collaboration with one of our customers on a pilot project for commercial sub-metering. Another investment we have made in the past 5 years is installing new meters. This week, members of our controls team were on hand at the BOMA Expo to help our customers understand the data and functions of these meters and how customers can use outputs from our meters to better monitor energy usage in their buildings. This is also a great way for customers to improve the performance of their building HVAC systems and reduce their costs.

Our team has also been busy expanding our heating and cooling distribution piping networks to serve new customers. This summer we expanded our system by 1500 trench feet to provide heating and cooling services to new customers including Higher Ground, the Palace Theatre, Seventh Place Apartments, and 333 Sibley.

Providing reliable and efficient service to our customers requires investments. The District Energy team, including its Board of Directors, makes it a priority to keep our rates stable as we make prudent investments to keep our systems reliable and operations efficient. Throughout our 34 years of providing heating service to downtown Saint Paul, we have raised rates 17 times. While we have kept our demand rates flat for five years, starting October 1 our customers will see an increase in our demand rates for both heating and cooling services. The demand rate for heating will be going up by 1.9%, however, the expected overall heating rate (energy plus demand) paid by our customers is projected to be unchanged from the 2016 budgeted rates. Similarly, the overall cooling rate (energy plus demand) is projected to increase 1.4% over the 2016 budgeted rates. Both rate increase remain below the rate of inflation.

Our team strives to improve our operations, optimize our processes, and grow the system with a constant focus of keeping our rates stable and cost-competitive while maintaining our high standard of reliability. We also want to work collaboratively with you to help you save energy and money. As you prepare for the heating season, please check out the tips to maintaining your heating systems to keep your building systems performing well and operating at its best. Please reach out to our team as a resource. Our people are highly trained, and we serve hundreds of buildings, all of which generates tips and ideas that we are happy to share with you to help you save money.  Please do not hesitate to reach out with your questions or for help with your building projects.

Prepare Your Systems for the Heating Season

As we look toward the crisp days of fall, it is a good time to prepare your building systems for the heating season. Scheduled and preventative maintenance can keep your building’s systems running efficiently, extend equipment life, and help to avoid unexpected downtime and costly repairs. The District Energy team has developed a list of recommendations to help keep your heating system running smoothly. These steps can be incorporated into the maintenance program for your building. For personnel safety and to protect equipment, maintenance tasks should be performed by qualified and trained individuals. Preventative Maintenance Check List – Fall.

Join Us at the Operating Engineers Seminar

Please save the date for our Operating Engineers Seminar on Tuesday, October 18, 2016, from 11:30 AM – 1 PM. This annual event is an opportunity for engineers that work in customer buildings to connect with our experts to better understand aspects of running and optimizing their system. Join us to ask your questions and to learn how to get the most out of your District Energy connection. Additional event details will be coming soon.

Ron Anderson Moves into Plant Superintendent Role

Anderson-Lujan

Ron Anderson & Pete Lujan

Pete Lujan and Ron Anderson both joined the District Energy team in 1983, with start dates just months apart. They have been working together since the steam-to-hot water transition and before the cooling system or St. Paul Cogeneration were built. This month when Lujan retires, Anderson will take over his responsibilities in the role of Plant Superintendent.

Through their years of service, District Energy customers have benefited from the dedicated service of Lujan and Anderson. Their intricate knowledge of our equipment and operations helps to keep the system reliable.

Anderson joined District Energy as a general helper doing various jobs in the plant from assisting on maintenance projects to handling fuel. Most recently Anderson has served as one of the Lead Engineers, responsible for one of the control room crews that keeps a constant eye on heating, cooling, and cogeneration operations every hour of the day. In his new role, he is looking forward to the opportunity to work at a new level within the organization, coordinating across departments, and being more involved in the decision-making that ensures the continuation of safe and reliable service to District Energy customers. He said, “The services that we provide are top-notch. I am proud of being a part of that. District Energy is an integral staple of the city and not just a great place to work.”

Lujan started at District Energy in the role of Lead Engineer, and he was promoted to his current position in 1993. He has been a part of the growth of the business and the expanded service offerings to our customers. He is most proud of the fact that all along the way we have maintained a high reliability of services. Lujan said, “Our greatest value is that we offer worry-free services. Our customers can come into work in the morning and their heating and cooling is working. They can worry about other things.” As Lujan looks toward retirement, he is looking forward to transitioning from Minnesota winters to winters in Florida.

Sun Spot

Sun SpotSun Spot is a new art installation that brings together the river, solar energy, and the proposed River Balcony. Sun Spot is a 15 foot long bench in the shape of an aerial view of the Mississippi flowing through Saint Paul. The bench is connected to a meter that collects solar activity data throughout the day. Each night Sun Spot will be illuminated by the solar activity collected through that day. The bench will be lit up from dusk until dawn, showing the solar energy collected through the panels roughly twelve hours beforehand. Sun Spot will provide visitors a unique river overlook between District Energy Saint Paul and the Science Museum of Minnesota, in the heart of the Saint Paul EcoDistrict.

Sun Spot is a project led by Alyssa Baguss and Aaron Dysart that debuted at the River Balcony Prototyping Festival on Saturday, September 10. The bench will remain on display through November 10. Come visit Sun Spot at night or during the day, however, the light show begins after dusk.

Right Track Intern at District Energy

Anderson-Vang

Paige Anderson & Sabrina Vang

This summer our organization had the pleasure of hosting a Right Track intern, Sabrina Vang. Right Track is a Saint Paul program that brings together the business community and the public schools to connect motivated students to work-readiness training and paid professional internships.

This summer, Vang’s work at District Energy covered a wide variety of projects from research for the Saint Paul EcoDistrict to helping our office manager audit office equipment. Vang also participated in several informational interviews with professionals in the energy sector. Every week, Vang attended training with Right Track where she learned communications, public speaking skills, basic Excel skills, how to use Word documents, and more. From Vang’s perspective, this internship helped her gain confidence and understand how to better work in a professional workplace.

Going into her junior year at the Washington Technology Magnet School in Saint Paul, Vang has demonstrated that she is a motivated student. The week prior to her internship, Vang attended Michigan Tech’s Women in Engineering summer camp. At this camp she was able to learn about different fields of engineering and partake in projects that gave her a feel for each field.

Along with her internship at District Energy, Vang works part-time at the Science Museum of Minnesota’s Kitty Anderson Youth Science Center. Her most recent project has been developing a mobile app for Frogtown Farm. Before working at the Kitty Anderson, Vang participated in their after school program “Design Team.” In this program students do mini, hands-on projects that teach the fundamentals of STEAM-science, technology, engineering, arts, and math.

Vang’s interest in science is fueled by her love of the outdoors. When asked where her interests might lead her, Vang said, “I would really love to study hydrology, because I believe that everyone in the world should have access to fresh water, and because there are some areas on earth that don’t have access to fresh water. I would like to help them.”

This summer, when Vang was not working one of her two jobs or attending engineering camp, she spent her time watching Korean television dramas, hanging out with her friends, and, of course, playing Pokémon Go.

Vang joined a second intern working with our organization this year. Paige Anderson worked as the Student and Community Engagement to help engage college students in the International District Energy Association annual conference hosted in Saint Paul this summer. Anderson will remain with the company through the reminder of the school year working with the public relations team and helping to build additional education networks for students and our business.

The International District Energy Association (IDEA) annual conference arrived on our doorstep on June 20th and provided four days of exciting education and dialogue, innovation sharing, and opportunities to showcase our city, our system, and our region. Like district energy, the association has been around for over 100 years to help cities, campuses, communities, and businesses to develop solutions, best practices, and connections that help advance energy systems. This past week, I think we exemplified our industry’s capabilities and our great potential by engaging more people in the energy conversation.

To kick things off, Mayor Chris Coleman received a United Nations recognition for the City of Saint Paul as one of three Champion Cities in the United States. This distinction honors urban areas committed to developing and sharing district energy policies with other cities and working cooperatively toward a cleaner, more resilient future. In total, the United Nations has named 45 Champion Cities around the globe. We are so proud of our longstanding partnership with the City of Saint Paul, which has helped earn this great recognition. We will continue to work together toward resilience and environmental progress for our community.

The rest of the week was a whirlwind of amazing presentations, forums on developing future industry talent, dinners at our fantastic local restaurants, and tours of our solar installation and central plant, as well as facilities in Minneapolis and the University of Minnesota Campus. It was tremendous to share what we have learned about technology integration, customer service, utility business management, and our education and engagement programming with our industry peers. Folks were even asking if they could come back to Saint Paul every year! It is an impressive compliment to have this audience see the value in connecting with the experts and leaders in our region.

Rydaker-&-Thornton-Life-Member-Award-NLDuring the conference, our former President and CEO, Anders Rydaker, was presented with the Life Member recognition. Anders has done so much for our system, our industry, and the community. We are grateful for his momentous contributions and to be continuing the legacy he has established.

In my time with this company, I have had many proud moments, but hosting this event will certainly rank near the top. I am so proud of our team for helping the incredible IDEA team to host over 800 attendees and representatives from 19 countries and 246 different cities. As our customers and our partners, I am grateful for all of your efforts to help us with this internationally significant event and supporting the growing importance of smart and efficient energy systems.

Saint Paul Presented with Champion City Recognition

Mayor-Coleman---Thornton-&-Riahi-UNEP-recognition-NLThe United Nations Environment Programme (UNEP) recognized the City of Saint Paul as a “Champion City,” a distinction honoring urban areas committed to developing and sharing district energy policies with other cities and working cooperatively toward a cleaner, more resilient future. Mayor Chris Coleman accepted the award on behalf of the city, as part of the official opening of the 107th Annual International District Energy Association (IDEA) Conference and Trade Show hosted by District Energy St. Paul. The mayor was praised for his long-time commitment to the city’s sustainability and district energy policies.

“Local leadership and support from city government is critically important to accelerating deployment of district energy as a sustainable, low-carbon energy solution,” said Robert Thornton, president and CEO of IDEA. “We want to commend the City of Saint Paul for understanding the vision and potential of district energy and for being a true partner in enabling this world-class asset to fully realize its potential.”

“The City of Saint Paul is proud to receive this recognition from the United Nations and join these other distinguished cities in promoting solutions for sustainability and planning for our changing climate,” Mayor Coleman said. “We are fortunate to have great partners in our community, including District Energy St. Paul, who have helped the city advance its environmental achievements and set more ambitious goals for our next generation of smart energy infrastructure, energy efficiency, and renewable energy.”

In addition to hosting this year’s conference, the Twin Cities region is home to dozens of district energy systems serving cities, communities, and campuses. As a UNEP Champion City, Saint Paul joins a network of more than 45 global Partner Cities, such as Copenhagen, Denmark; Helsinki, Finland; and Dubai, United Arab Emirates, sharing insights and experiences with other communities around the world to accelerate the deployment of district energy in metropolitan areas.

District Energy St. Paul Earns Bronze and Silver Awards for System Growth and Retention

Annually since 1990, the International District Energy Association (IDEA) has polled its member district energy systems to report the number of buildings and their area in square feet that have been committed or connected to district energy service during the previous calendar year. In recognition of service growth and retention, the top three organizations in each category are recognized during the annual conference.  For 2015, District Energy St. Paul earned a Silver Space Award for number of buildings committed in the North America category. We were also honored to earn the Bronze Space Award for total building area committed in the North America category. Beyond the award recognition, District Energy is pleased to see new customers joining our heating and cooling systems, and that our customers continue to choose us as their preferred service provider. We will continue working hard to build our value proposition to our customers and earn new business and customer loyalty.

Sharing What We Have Learned

Phil-Bourne-presents-IDEADistrict Energy St. Paul prides itself as a dynamic organization that is constantly looking for ways to learn, grow, and improve. We have worked hard to keep our Saint Paul system as an international model, and we are proud that our facilities and our team members can share their learnings with others in the industry and our community. During this year’s IDEA conference, our team shared our experience with technology integration, business development, utility and operation optimization, and community engagement through presentations and facility tours. It was particularly exciting to host over 200 people in our plant and over 50 people on the roof of the Saint Paul RiverCentre to learn about our large-scale solar thermal installation. We had an engaged audience, and we hope we helped other systems realize their technology integration potential. Visit our photo gallery to see great images from our tours, captured by local photographer, Mike Krivit.

Conference presentations were given by Michael Ahern, Nina Axelson, Phil Bourne, Ken Smith, Ray Watts, and Cathy Hart.

Inviting the Community to the Conversation

Really-Big-Table-conversations-NLDistrict Energy takes pride in being a community-based organization, which means inviting the community into the work we do and how we plan for our energy future. Hosting the IDEA Annual Conference provided us with a unique opportunity to create a community event to share emerging energy trends, showcasing Minnesota and international perspectives. Our team facilitated a dynamic and informative speaker session, sharing a broad range of perspectives on our current and future energy systems, with the intention of opening up new conversations and connections between industry professionals, citizens, educators, students, government representatives, and business leaders. The speakers included Commissioner Shawntera Hardy (Minnesota Department of Economic Development), Ken Smith (Ever-Green Energy), Jakob Bjerregaard (Danish Embassy), Werner R. Lutsch (The Energy Efficiency Association – Germany), and Dr. Massoud Amin (University of Minnesota). It was a riveting session that we hope sparked new ideas for working together to advance our energy systems and bring more people into the discussion.

We were also thrilled to host an engagement reception to connect higher education students, teachers, local leaders, experts, and conference attendees. We featured unique art and science engagement activities, including the new Water Bar and the Really Big Table (to share really big ideas), a project connected through the Springboard for the Arts Ready Go program. It was a tremendous evening with new experiences, new connections, and we hope it opened up the potential for future community energy conversations.

Connecting Customers

Customer-Appreciation-2016Connecting with our customers is an essential part of improving our business. We try to connect with customers throughout the year to better understand how to better serve their needs and help them optimize their interconnection with District Energy. We are grateful for our many partners and the incredible loyalty of our customer base, and we host a special event each year to show our gratitude. At this year’s customer appreciation day we hosted more than 50 customers at our new office in the historic Jemne building on St. Peter Street and Kellogg Boulevard. Our new building showcases how older or redesigned buildings can be retrofitted with technology that efficiently connects to our heating and cooling system, including a unique pre-assembled mechanical skid. During the event, customers had the opportunity to see the new mechanical system and tour our new office space. In addition to this event being a great opportunity for our team to connect with customers, it was also a great chance for customers to connect with each other. Thanks to those of you that were able to attend the event. As always, we encourage you to contact our team if you have any questions about your services and how we can serve you better.

Connecting with the Saints

Game-of-Catch-2016Just days before the Saints kicked off their second season at CHS Field in Lowertown, we were happy to sponsor the World’s Largest Game of Catch in collaboration with Saint Paul’s leading experts on fun. In addition to playing ball and meeting players, our team had a great time meeting people who live and work in buildings we serve. Community events like this offer us a great opportunity to meet more District Energy customers and talk to them about how to efficiently and effectively use our system. The Saints have also created a great opportunity for us to connect with Saint Paul’s next generation of leaders, local students. This year we sponsored the Education Day activities, including a parade to CHS Field. We were also thrilled to work with the Saints to create a short science and energy education film to help students better understand where some of their energy comes from. The Saints have been a tremendous partner in helping us promote our energy education initiatives and bringing so much vitality to downtown.

The world is coming to Saint Paul to talk about energy. Now is the perfect time for this conversation as global energy systems are undergoing historic changes. During June 20-23, 2016, the International District Energy Association’s annual conference and trade show will be in town, and District Energy St. Paul is thrilled to be hosting this important event, with 1000 people expected from across the United States and over two dozen countries. This is an incredible opportunity to showcase our energy system and the region to our peers, other cities and campuses, and over 100 vendors providing services to this growing industry.

We worked closely with our partners at Visit Saint Paul to attract this large conference, and our city was selected because of our outstanding achievements in community energy, and the innovative work happening in the local energy sector. The Twin Cities region is home to dozens of district energy systems serving urban centers, campuses, health care, and private developments. Our region is providing leadership in the crucial areas of energy, infrastructure development, and the environment, with the intent of creating a more efficient, more cost-effective, and more sustainable energy system.

This year’s conference theme is Embracing Change. During the event, we will join local, national, and international leaders to outline the next big ideas to advance the energy future for communities and campuses. We see this conference as a timely opportunity to address important topics such as improving energy system resilience and efficiency, and reducing carbon emissions. District Energy St. Paul has worked for decades to address these topics and demonstrate solutions within our system. Our local facilities will serve as a feature tour for the conference goers, giving us the opportunity to share what we have learned in the advancement of our system and our plans for the future.

As we prepare to welcome the conference attendees to Saint Paul, we hope that our customers and local partners will help us to roll out the red carpet for this important event. Saint Paul and the region have so much to offer between the great restaurants, beautiful architecture, natural resources, and recreation. We can’t wait to share our story with the rest of the world.

Happy move-in week for Custom House tenants. We are pleased to welcome Custom House and their tenants to our local energy system that connects most of downtown Saint Paul. The Custom House is an exciting large-scale renovation project of the former US Post Office and Custom House building. The 1930s vintage, art deco building has been transformed into apartments, a hotel, and self-storage. The renovation highlights many of the building’s historic features which were restored during construction, including the beautiful lobby space that will create a grand entrance for residents and hotel guests. Custom House offers stunning views of the Mississippi River and Saint Paul as well as first-class amenities.

This is the first project in downtown Saint Paul for the Exeter Group. According to Herb Tousely, Chief Development Manager, the group was attracted to the Custom House site because the building offered stunning art deco features and unparalleled views of the Mississippi River and the city. Additionally, the floor plans in the main tower were ideal for housing and hotel conversions. Herb noted that, “There is a lot of positive momentum in downtown, and we have really enjoyed being a part of the renaissance that is happening here.” Herb and his colleagues have enjoyed watching the progress of this project. Herb shared, “The finished product has exceeded our expectations. It has been rewarding to see the reactions of the new residents that are moving into the building.”

District Energy is happy to contribute to this exciting project, providing Custom House with heating, cooling, and snow melt services. Our team has been working closely with Exeter to connect the building to the system and accommodate their needs throughout construction. Herb said, “We have really enjoyed working with District Energy. There are many benefits that come with using their services including 24/7/365 heating and cooling, which helps to eliminate heating and cooling issues in the shoulder seasons. By connecting to District Energy we avoided the need for the large unsightly HVAC plants, required by a more traditional cooling system, cluttering up our rooftop.”

At Custom House, the housing construction will continue through June. Self-storage services that will be located in a portion of the building that originally served as the Postal Service Annex will open in June. The Hyatt Place Hotel is targeted to open in September. The group is working to identify a restaurant that will occupy a portion of the first floor. The Custom House residents, guests, and amenities will be a wonderful component of the Saint Paul River Balcony project, including this September’s Prototyping Festival.

Congratulations to everyone involved in this immense project. We look forward to continued collaboration with the Exeter Group and service to this amazing building. Welcome to the neighborhood.

Customer Appreciation Day – May 24, 2016

District Energy is looking forward to our annual opportunity to celebrate and thank our customers, scheduled for May 24th this year. Customer Appreciation Day will take place in our new offices in the historic Jemne building on St. Peter Street. We will be offering tours of the building to give people a glimpse inside the building’s renovations, HVAC and mechanical upgrades, and to learn more about the history and architecture. Lunch will be served (RSVP is requested). Please contact lisa.eng-sarne@ever-greenenergy.com or 651-925-8129 for questions or to RSVP.

District Energy demand and energy charges

District Energy heating and cooling service rates are comprised of two primary charges: the demand charge and the energy charge. Demand charges are primarily associated with the system costs for infrastructure, operations, and maintenance. The energy charge is a pass-through of the system energy costs based on our cost to secure fuels and electricity to produce hot and chilled water and does not include a markup. The energy charge varies by a customer’s usage.

District Energy utilizes a variety of fuels, which allows for increased reliability and the flexibility to avoid market fluctuations to keep costs stable. The energy charge is projected by District Energy and shared with customers at the beginning of each fiscal year. Throughout the year, the energy charge may be appropriately adjusted through the fuel adjustment charge to cover cost increases or decreases against the actual cost of the energy purchased.

District Energy customers have seen their hot water service invoices reduced recently, due to decreased energy costs. The March hot water energy charge totaled $20.00 per megawatt-hour (MWh) based on an energy rate of $25.59 per MWh and -$5.59 per MWh for the fuel adjustment. The March chilled water energy charge of $0.087 per ton-hour is based on an energy rate of $0.087 per ton-hour and no fuel adjustment charge. Fuel adjustment charges will change periodically based on changes in energy input costs.

We are glad to be able to pass this savings along to our customers. We are committed to providing our customers the most cost-competitive, reliable, and local energy option.

EcoDistrict partners honored with Sustainable Saint Paul Award

sustainability awardThe partners of the Saint Paul EcoDistrict were honored on April 20 with the Sustainable Saint Paul Award in the category of sustainable partnership. The award recognizes individuals and organizations that have made a commitment to create a more sustainable Saint Paul. The EcoDistrict was made possible by the commitment of neighborhood partners including the Science Museum of Minnesota, Saint Paul RiverCentre and Xcel Energy Center, the City of Saint Paul, Visit Saint Paul, District Energy, Saint Paul Public Library, and Xcel Energy.

The partners’ commitment to sustainability has attracted students, local residents, and visitors from other cities to learn from the environmental innovations and sustainable practices within this four block, walkable area of downtown. From renewable energy to waste reduction, the practices within the EcoDistrict are demonstrated with the intention of encouraging other businesses and communities to explore and incorporate sustainability. Through a partnership with Climate Generation: A Will Steger Legacy, the EcoDistrict partners are finalizing a field trip curriculum to extend the reach, influence, and access to these technologies and applications.

While most people will experience the EcoDistrict through self-guided tours, the partners have hosted guided tours for several groups including the Solar America Cities partners, NOAA, the International Energy Agency, Central High School, and other local schools. Last week partners hosted a group of individuals from Nashville, TN, that are working on issues and opportunities around transit and development in their city. In early May, the partners will be hosting a tour of attendees for the USGBC Minnesota’s IMACT Conference.

Congratulations to all of the award winners that are doing great work in our city, including our customers CHS Field, Regions Hospital, and Landmark Center.
