Steam Heat, Detroit Thermal, and Powering Greater Downtown Detroit
For more than 100 years, Detroit Thermal has served many of Detroit’s buildings, including GM Renaissance Center, Huntington Place, Fox Theatre, Detroit Medical Center, Ford Field, The Fisher Building, the City of Detroit, and Wayne State University. In 2021, the company enrolled in DTE’s MIGreenPower program. A voluntary renewable energy program, MIGreenPower enables DTE electric customers to attribute a greater percentage of their energy use to Michigan-made wind and solar beyond the 15% DTE already provides. Detroit Thermal’s goal is to gradually increase its MIGreenPower enrollment to attribute 100% of its electric usage to renewable resources by 2030. SBN Detroit spoke to Todd Grzech, Detroit Thermal CEO, to learn more about how both steam heat and the company’s enrollment in the program impacts Detroit. Q: Tell us more about Detroit Thermal. A: Detroit Thermal is the district energy heating system for the city of Detroit. We’ve been delivering clean steam energy to the greater downtown Detroit area and services through an extensive underground network of steam piping for over 100 years. Detroit Thermal was one of the original district energy systems in the country and is a critical piece of Detroit’s energy infrastructure and we currently provide energy services to more than 100 buildings. Q: Is Detroit Thermal considered an alternative utility to DTE? A: Typically, we don’t see ourselves as that. We are more of an alternative to property owners providing their own heat energy, and we utilize DTE electric and natural gas to provide steam heat. Q: What are the benefits of steam over electricity? A: Energy savings and cost savings. From A BTU conversion standpoint per dollar, steam beats electric by a lot. Electric heat is very expensive. An analogy I like to use is the comparison between an incandescent light bulb and an LED. The amount of energy and the process required to turn the electricity to heat is much more complicated than steam heat – and there is waste in that. Another thing with steam from a pressure perspective is that it finds its own lower pressure area so we don’t need mechanics or fans to move the heat. Think of a steam pot when you see the steam moving. Its energy alone transfers the heat. This is not the case with electric heat. Q: Are you serving both older buildings and new builds? A: Yes. In Detroit, older buildings like the Fisher and Cadillac Place are piped for steam and have radiators that are designed for steam heat. Newer buildings are using hot water to create steam. A great example is Bedrock’s new Hudson’s site. It is connected to our underground system. The building is piped to carry hot water throughout. Steam heats the water, and the water moves through the piping to heat the spaces. It’s a closed-loop system in that the same water continues to be heated, then moves through the pipes, which is very efficient. Q: What are the challenges/barriers to entry when it comes to using Detroit Thermal for steam heat? A: The main challenge is geography. Where a building is located in relationship to our underground system. If it’s close to the system, it’s usually relatively easy to connect. If the building is too far away, it might be cost-prohibitive to run a pipe to connect just one building. When it comes to our infrastructure it’s about density. The more buildings that can share a single line the more cost-effective it is. There is a cluster of density in the central business district. The underground piping system does a loop basically from Ford Field to Huntington Place around and back. The Hudson’s site is pretty close to that loop so we just needed to run about 100 feet of piping off of that system to connect it. When you get farther away from the central business district piping might not make sense. On the consumption side, steam heat gets interesting as well. When we look at office buildings where operators are looking to maintain a nice temperature for all workers, steam heat is very effective. On the multifamily and apartment side, it’s desirable to have a unit in each space that can be metered and billed. You can’t do that with steam heat. Q: Is the steam used for heat only, or are there other uses within the buildings and businesses? A: It is used largely for heat but, yes, there are other uses. Some entities use steam for pressure, such as breweries. Russell’s Pharmacy in the Fisher Building uses it for its pharmaceutical processes. Hospitals use it for the sterilization of equipment. Restaurants can use it to clean dishes. Q: In 2021, Detroit Thermal enrolled in DTE’s MIGreenPower program and is gradually increasing its MIGreenPower enrollment to attribute 100% of its electric usage to renewable resources by 2030. The company’s commitment is said to ultimately offset the carbon dioxide equivalent of greenhouse gas emissions from over 1,000 passenger vehicles driven for a year. Can you tell me how this works? A: Basically, we pay a premium today to support DTE’s development of solar energy and wind farms. With growth here, these sources become less expensive, and over time dollars are spread further to reach 100% of the electrical supply. Q: Is this an accelerator for Detroit Thermal toward your goals to reduce carbon footprint and or switch to 100% renewable energy? A: Yes, it is in line with our overall goals to reduce our carbon emissions footprint. We are on the path right path to do so as DTE defined the program. Q:How do you think this enrollment and the overall work you are doing make an energy impact on the City of Detroit and the overall region? A: I think, really, all companies in Detroit are working hard toward reducing energy consumption. From an energy consumption perspective, we consider ourselves to be like a co-op. if we are making energy improvements everybody gets the benefit – not only the company that is doing that locally. So, as we
Huntington Place Detroit – Green and Working Toward Greener
What was Cobo Hall opened its doors as one of the nation’s first mega-conference centers in 1960 and has served as a venue for sports teams, concerts, speakers, and more. In fact, on June 23, 1963, following the Detroit Walk to Freedom civil rights march, Martin Luther King Jr. delivered the original version of his “I Have a Dream” speech at Cobo Arena. Having under gone a $279 million renovation in 2015, and several name and sponsorship changes since, Huntington Place Convention Center now features a 30,000-square-foot, three-story glass atrium overlooking the Detroit riverfront, the largest ballroom in Michigan at 40,000 square feet, and 723,000 square feet of exhibit space. That’s a lot of space to maintain, and sustain. The facility also is the largest and only convention center in the world certified under LEED v4.1 Operations and Maintenance (O+M), as well as Michigan’s largest certified green LEED Building. The facility contributes 9.8 tons of unserved food to Forgotten Harvest and sends 66 tons of compost annually to Hammond Farms and also has 110 recycle bins, 10,000 square feet of green roof, five beehives that retain 10,000 bees, and numerous awards for its green efforts. How did it get here, and what can other businesses and nonprofits glean from their work in this area? Cedric Turnbore, director of operations and chair of the Huntington Place Green Committee, shares his insights on where to begin when approaching a sustainability program, the why behind it, and some examples of initiatives Huntington has put into place to date. WHERE SHOULD A BUSINESS START? #1: Form a Committee “In 2011, we developed the Green Team, a committee that includes one person from each department in the office building,” Turnbore says. “We meet regularly to review programs and goals.” The center also has a 5-person executive board established by the state of Michigan to oversee its sustainability efforts. “The board acts as our governing body that oversees and approves our programs. We work closely with them to set and manage budgets and ensure that initiatives are in the best interest of the facility, the employees, our guests, and the city.” #2: Set Attainable Goals “Start with the low-hanging fruit,” Turnbore said. “Things you can achieve in the near-term that will help to gain traction for the long haul.” Initial goals of the Green Committee in 2011 included growing the committee with representation from each department and vendor partner and organizing operations around the Green Venues Michigan certification. Since the United Nations set for 17 Sustainable Development Goals in 2015, Huntington Place has patterned its work around them. When the TCF Center Green Committee reconvened in September 2021 after a COVID-related hiatus, those goals were front and center. “This will be pivotal year for our sustainability program,” Karen Totaro, general manager TCF Center/ASM Global, said at the time. Our work in the center is to contribute to the United Nations Sustainable Development Goals and re-certify as the largest LEED venue in Michigan will be front and center for our efforts in 2022. Turnbore said so far the center has been able to implement projects contributing toward 13 of the 17 goals, and the work will continue. #3: It Takes Green to Go Green “Businesses must commit to funding for the necessary equipment, tools, and programming,” says Turnbore. “That’s why we have a board … to govern and approve our spends and ensure that those spends have the desired outcome – a return on the investment.” Some examples of investments Huntington Place has made include 110 recycling stations, food court waste diversion receptacles, visitor education posters, a green roof, receptacles for compost collection, trash compactors, a cardboard baler, and a green website page for visitor information. #4: It’s a Marathon, Not a Sprint “When we first launched our efforts 11 years ago, many individuals thought it was a fad. That the sustainability work would ‘go away. You need to have a long-term plan to ensure that it never goes away and be steadfast in your efforts every single day. It’s as simple as that,” says Turnbore. #5: Educate! According to Turnbore, for their efforts to be impactful, it’s imperative to continually educate employees, vendors, and visitors on the how and the why behind them. To that end, every new employee is trained on conservation and sustainability during onboarding. Information is posted throughout the facility. The sales and events team with vendors toward making every event as green as possible. Vendors are offered a post-event sustainability report outlining diversion data, compost data, and best practices observed during the event. Further, the team tours sustainability partner facilities to observe first-hand how their efforts are working. The committee recently toured Hammond Farms in East Lansing, which composts more than 66 tons of unused food from Huntington Place events annually. WHAT EXAMPLES DOES HUNTINGTON PLACE HAVE IN PLACE? According to Turnbore, Huntington Place’s four biggest priorities are waste diversion, energy savings, food waste management, and employee education. Here are just some of the green initiatives currently in place: Sitting off the Detroit River, Huntington Place HVAC system pumps gray water from the Detroit River through chillers that then send the cool water to various air handlers, providing cooling to zoned areas in the center. This system uses considerably less electricity than conventional air conditioning units. The Huntington Place $279 million facility upgrade incorporates numerous green building components including low-flow restroom and kitchen equipment, energy-efficient HVAC equipment, and a living green roof. Centerplate, the Huntington Place food and beverage provider collects prepared food that has not been served for pick up by Forgotten Harvest, a local nonprofit that delivers the food to pantries, soup kitchens, and shelters throughout Southeastern Michigan. Materials left by events are donated to local agencies for reuse and upcycling. Exhibit halls are equipped with induction lighting that uses 50% less electricity. All main hall lighting and heat/cool settings are computer programmed and managed. Escalators in the building are energy efficient, Kone EcoMod units. Escalators operate based on occupancy and
