Wiegmann Associates has begun HVAC work on the 22-story apartment and retail building 270 Hennepin Avenue in Minneapolis, Minnesota.
As the Engineer of Record and mechanical contractor for the design/build project, Wiegmann is responsible for designing and installing the HVAC system and a Building Automation System for the entire 480,000-square-foot, multi-use building. The general contractor is Weis Builders and the architect is Tushie Montgomery Architects. The co-developers are CA Ventures and Harlem Living.
The HVAC system will feature a central plant with a cooling tower, pumps and boilers, which will distribute condenser water to water-source heat pumps to serve the 346 residential apartments, 20,969 square feet of retail space on the ground level and amenity spaces with optimal comfort and energy efficiency. Amenity spaces include golf simulator and game rooms, private dining and party rooms, yoga studio, fitness center, sauna, an indoor spa pool and spa outside on the 19th-floor deck.
Providing ventilation for the two floors of underground parking posed major HVAC design challenges. Between using building information modeling and close coordination with the architect, Wiegmann was able to identify acceptable locations for the heating and ventilation equipment that will maintain clear height requirements.
