Serene and remarkable, Lakewood Cemetery has provided visitors a place of solace for over 150 years. Situated between Lakes Harriet and Bde Maka Ska, the landmark cemetery houses multiple facilities for welcoming guests and offering funeral services in addition to expansive grounds for visitation and reflection.
Lakewood has embraced a progressive approach to sustainable operations with a geothermal system that subtly blends in with the awe-inspiring architecture and natural environment of the area.
Constructed in 2022, the system uses two 12″ diameter wells combined with a central heat pump to provide thermal comfort throughout all seasons of the year.
Midwest Mechanical Solutions is a manufacturer’s representative of applied mechanical equipment used in HVAC systems, working with Darcy Solutions as an exclusive partner in Minnesota. They are experts in commercial and industrial applied systems of all kinds including chillers, boilers, variable refrigerant flow, rooftop units, direct expansion and much more.
After multiple years of representing Darcy Solutions in the market, MMS decided to install a one well system as the primary thermal capacity for an office expansion in 2022. The system uses one 12″ diameter connected to a VRF building side equipment. Like other elements of their HVAC equipment on within the building, the geothermal equipment is highly visible and used to showcase design considerations to customers.
The company is using the newly constructed geothermal and distribution equipment within the building to capture the Investment Tax Credit.
Renewable Energy Partners is a clean technology project developer working at the heart of the energy transition. With each project the company provides hands-on experiences to educate new generations of the workforce on skills necessary for designing, building, and operating energy projects. The company is focused on solar, energy storage, geothermal technologies and always looking for new renewable and efficient technologies.
This project was a retrofit the existing HVAC system to a one well geothermal design using a central heat pump for heating and cooling. The building is an excellent example of decarbonization possibilities, using a solar array on the roof coupled with an energy storage system to generate and store electricity, which is used to power the geothermal system now in place for heating and cooling throughout the year.
The project started construction in 2022 and was commissioned in the Spring of the following year. REP used the project to capture the Investment Tax Credit available in the Inflation Reduction Act.
St. Paul Pipefitter's Local 455 is a training facility for steamfitting and pipefitting licensed professionals. Since 1904 the organization has been training local skilled workers for HVAC systems and services of all kinds across the Minneapolis / St. Paul metro and beyond. Year after year the organization graduates skilled labor to build the next generation of clean energy infrastructure.
“The Darcy Solutions system is very energy efficient; we have been using it for multiple years for cooling the entire facility. It’s easy to operate and an excellent way to show the skills to build new energy systems we train our teams on every day.” -- Jeremy McConkey, Training Director UA Local 455 JATC.
This is the first commercial Darcy system, consisting of four eight-inch diameter wells situated along the Eastern perimeter of the facility parking lot. Pipefitters has a long history of incorporating new technologies installed by their craft workers.
After initial consideration of a traditional geothermal system, the organization opted for a Darcy system which limited construction in their parking lot, time for installation, and now provides extremely efficient cooling via chilled beams within the building. The site is frequently used as a tour to provide information on equipment and the skilled trades that install them.
Lake Waconia Regional Park is a 164-acre park East of the City of Waconia and a mainstay of leisure for city residents and tourists. The Paradise Commons building is a newly constructed public waterfront services center. The building provides visitors of the Lake Waconia Regional Park access to restrooms, covered seating, gathering spaces and meeting rooms to rent.
This building was constructed using a total of $5M of state and county funding. Buildings that receive funding of this sort are required to meet the B3 SB2030 Standards for energy efficiency. Those requirements led the architecture firm associated with the project to recommend geothermal and solar on the roof. The project includes three total Darcy wells which provide heating and cooling up to 110 tons of capacity.
