Energy Efficiency Using Geothermal Heat Recovery Chiller

Located in Williston, N.D., Mountrail-Williams Electric Cooperative is adjacent to a natural pond used for stormwater drainage. With the facility being an electrical cooperative, the design team used the element of a curved electrical conductor as part of the building’s shape. The HVAC system uses geothermal heating and cooling for the entire building. The modular design allows for improved efficiency and load shifting between heating, cooling and the well field as the heat sinks. The facility directors also requested mechanical equipment that would last the life of the building.
