Graystone Heights

Apartment Complex | Sioux Falls, SD

West Plains Engineering provided mechanical and electrical design services for the newly developed four-building complex, which includes 331 units with an underground parking garage, community and fitness centers, theatre, spa, indoor and outdoor pools.

The mechanical systems consist of heating and cooling provided by high-efficiency gas-fired furnaces and Dx cooling. High-efficiency furnaces provide the heating, cooling, and ventilation to each apartment. Exhaust fans were provided for each restroom to remove moisture-laden air. An exhaust fan is also provided to remove odors from each trash chute vestibule on each floor. A central group of high-efficiency gas-fired water heaters were used to provide hot water to each apartment. Each building has a central gas and water meter, and gas and water utilities are included in the rent, allowing the building tenants a fixed expense.

Primary electrical service for each building is a pad-mounted transformer and provides a secondary voltage of 208/120 volts, 3 phase, 4-wire. Each building has approximately 80 units with only one master meter to provide the tenants their utilities as part of their rent.

Lighting for the entire complex is a mix of LED 2×4 and recessed can light fixtures. Each apartment unit has WIFI, coax, and fiber. The complex has an access security control system to enter the buildings.
