Energy Star Buildings
There are 10 Energy Star rated privately owned buildings in Eden Prairie.
The new Co-op building was built to a Green Building standard (although it was not 3rd-party certified, it is in the process of getting Energy Star certified). The GMPUC provided a number of rebates for the construction. The Co-op manager described the building:
The new Co-op building was built with energy efficiency in mind. The building envelope exceeds the state requirements. The roof is a continuous average R40 with 10” of polyisco foam at the roof edges (the state requires R23 roof insulation on commercial building in a northern climate). There is 4” of Styrofoam below the interior slab. The ICF exterior walls have continuous R25 insulation (the state require R9.3 wall insulation on commercial building in a northern climate). The Co-op installed triple glazed windows and took additional steps such as using local wood and water based stains to ensure limited impact on our environment. They chose energy efficient lighting throughout the store. LED lighting is in all of our refrigeration and outdoor lighting. We used lower wattage fluorescent tubes throughout the store. The store has dual flush EPA WaterSense certified toilets and installed low flow sprayers on the three compartment sinks. The refrigeration is energy star certified, and they opted to install a rack system versus individual compressors to save energy and to allow the reuse of excess heat from the refrigeration to heat water and help heat the building.
There are currently seven buildings in Maple Grove that are LEED Certified: Starbucks Maple Grove-Dunkirk Square, Kohl’s Maple Grove, Xcel Energy-Fleet Services Building (silver), Boston Scientific WL3 Expansion (silver), Boston Scientific Weaver Lake Campus, Fairview Bass Lake Clinic, and Great River Energy (platinum). There is also one building in Maple Grove that is in the process of becoming LEED certified: Arbor Lakes Senior Living Community. In addition, the Maple Grove Library was designed in accordance with the Buildings, Benchmarks, and Beyond (B3): State of Minnesota Sustainable Building Guidelines and is a LEED Gold Compliant building.
Maplewood also encourages local businesses to participate in Xcel Energy's Community Energy Efficient Sweeps to reduce their business's energy consumption and energy savings.
The new ICC700 Green Building code also have incentives built into the policy language to promote green building in the private sector.
Ryan companies has a low-rise multi family development in the city of Maplewood that is LEEDs gold rated.
The city, in collaboration with the Food Service Energy Leadership Program (housed at Eureka Recycling), applied and received a competitively selected Energy Efficiency Conservation Block Grant (EECBG) through the Department of Energy and administered by the Minnesota Division of Energy Resources. This grant, funded through the American Recovery and Reinvestment Act of 2009 (ARRA), allowed the city to provide technical assistance for energy efficiency among its restaurant community.
The program worked with 20 restaurants in the White Bear Lake area over a two year period. An initial energy assessment was completed by the technical team and a report produced with identified opportunities (focusing mostly on low-cost options). Throughout the course of two years of collaboration with these businesses, energy use was tracked and reported back to the businesses on a six month basis, and assistance was offered with larger retrofit projects, such as an HVACunit replacement, a new ice machine purchase, or a retrofit on the exhaust hood.
Overall, most businesses had 10-15 percent potential energy savings identified based on the initial walkthrough. The implementation of energy saving measures was left to the business, but on the whole recommendations were implemented. Over the two year period, the average energy savings in participating restaurants was 5.8 percent. These savings varied greatly depending on length of time in the program and ability to commit time, attention and money to making improvements.
By way of communicating the variety of actions participants took, and the variety of successes businesses had, this case study will briefly highlight the efforts of three White Bear Lake restaurants. More ideas, tips, case studies, and resources can be found at food.mncerts.org.
The Hanger Room
Getting started with energy efficiency needn’t be costly. Every business has opportunities for improved maintenance, repair, and changes in behaviors which cost nothing or almost nothing and save energy. The Hanger Room provides a great example of how simply paying attention to equipment and energy use can make great strides toward becoming more efficient.
Co-owners, Nick Miller and Peter Martinson chose a former bowling alley as the site for a new high-end restaurant. When considering the location, they looked into the energy use of the bowling alley. However, once they had added a larger commercial kitchen, complete with lots of equipment and a full wall of exhaust hoods, plus some additional refrigeration space, their energy use was different. According to Martinson, “Energy use in this building was a big surprise. We looked at the bowling alley’s energy use before buying the building, but our use is much higher.”
The owners needed to find a way to reduce energy costs without spending more money on new equipment or controls (a common situation for owners of new restaurants). Luckily, there were excellent opportunities to reduce their energy use that didn’t cost a penny.
Miller and Martinson set their programmable thermostats setbacks more aggressively, not only for occupied and unoccupied, but also for busy and slow times in the restaurant, zoning off areas that didn’t need to be heated or cooled until the dinner rush.
The other big saving action they took was to reduce exhaust hood runtime in the kitchen. Together with the head chef they implemented a plan where only one hood runs on slow days, and even then only when there is equipment beneath it running. Staff leadership has been important to the success of this strategy. Martinson says, “The chef has been the leader in the kitchen, working to keep equipment off until it’s needed. If we’re really slow, we don’t need extra equipment on. Sometimes two cooks will just share a stove.”
For a new restaurant establishing a baseline to compare energy savings is difficult. But Martinson and Miller are certain the small changes they have made are saving them money each month.
Dellwood Hills, an area golf course and restaurant, was enthusiastic to reduce monthly expenses by saving energy. Like most country clubs, the economic recession of 2008 left the club extra conscious of the need to run efficiently.
Ken Galloway, the General Manager of Dellwood Hills, was pleased to get some new ideas and support from the city energy efficiency program. “We’ve always tried to work efficiently and take advantage of programs and technology; but it’s so much more helpful and easier to embrace when you can get assistance from qualified people.”
Dellwood Hills will be retrofitting all of their inefficient T12 lighting to more efficient fluorescent lamps. Their timing coincides with Xcel Energy offering additional rebates because of the federal legislation phasing out T12 lighting. The lighting retrofit at Dellwood Hills will save the business over $7,700 per year, resulting in a project payback of less than one year. This project qualified for a rebate from Xcel Energy of almost $6,000, nearly 50% of the project cost.
In addition to lighting retrofits, Galloway has been talking to his staff about how they can help reduce energy use in various aspects of their job. Galloway suggests, “The key is to make energy savings real for them.” For instance, helping employees identify that leaving a door open wastes energy is more useful than telling them to “save energy.”
Sam Thai Cuisine
Little restaurants can save energy too. Sam Thai Cuisine, a tiny restaurant in a strip mall in White Bear Lake, doesn’t use a lot of energy to begin with, but after participating in the program they are more aware of energy use and have taken action to be even more efficient.
Sombat “Sam” Supunniam owns Sam Thai Cuisine, where he serves as head cook, dishwasher, repairman, cashier and friendly greeter. Despite using much less energy overall than the average restaurant, Supunniam still found ways to further reduce his energy usage.
Replacing gaskets, shutting off equipment and adjusting the thermostats were easy changes. Installing motion detectors on the bathroom lights made sense, since the bathrooms were infrequently used during the day. Supunniam appreciated the technical support, he said, “based on the auditor’s recommendation we realized the right direction to be working. We wanted to save energy because it’s the right thing to do, but for my small restaurant saving money is the most important.”
In fact, running such a small place allows Supunniam to arrange some creative agreements with contractors. “One of my customers said he could fix my lights, and I said that if he did, I would pay him in free lunches,” said Supunniam describing his arrangement that allowed him to retrofit old T12 lighting.
Five solar arrays have been installed on Woodbury commercial businesses, totaling 161 kW. There are four privately owned Energy Star buildings in Woodbury, in addition to a school and Woodbury City Hall. The buildings include: Goodwill, Target T0694, The Hartford, Kohls Department Store, Crosswinds School and City Hall.
The Washington County Environmental Center has a rainwater reclamation system for irrigation.
The University of MN, Duluth campus has decreased water use across campus by 30% in the last 11 years while increasing square footage by 15%. In the residents halls this has been done by replacing roughly 240 high consumption toilets with low flow models, installing sensor faucets with low flow aerators, and installing low flow shower heads. A new irrigation installed on the sports field will contribute to water savings. UMD has been investing in solar power, and between their solar arrays and purchases from community solar gardens received 244.82 MWH in 2018. While only .6% of their total energy consumption, it is a significant increase from 2009 when they received only 6.22 MHW, or .01%, of their energy from solar. An additional 100kW of community solar are going to be added soon.
Lake Superior Community College has reduced their energy consumption by 11% and water by 57% since 2009 while simultaneously increasing their psychical footprint by 10%. Energy reductions have been made by facilities upgrades including light retrofits, the installation of automatic controls, and parking lot lighting upgrades. Stormwater management has also been a priority for LSC and they have installed 3 rain gardens, an underground stormwater retention system, and numerous bioswales over the last 15 years.
Energy efficiency rebates from St. Peter Municipal Utilities to the state hospital are saving over $150,000/yr., reducing annual electric consumption by over 1.5 million kwh - or enough to power 211 average-sized homes annually.
