234 Market

Challenge

• Meeting an aggressive budget

Solution

• Utilize a closed loop water source heat pump system to maximize efficiency, reliability, flexibility, and limit exterior building openings.
• Each apartment is served by an efficient water source heat pump located in a closet with overhead exposed spiral duct to serve each tenant.
• The commercial spaces are also served by the same core water source heat pump system as the apartments which increases the diversity and efficiency of the entire system.
• There is a highly efficient boiler system to maintain a minimum temperature in the water loop and an open style cooling tower for heat rejection.
• There are separate energy recovery ventilators on each level to serve the ventilation requirements from a central location, therefore no individual exhaust fans were required, and the ventilation air is also delivered directly to each heat pump.
