Wiegmann Associates has begun HVAC work on the new $48.5 million, 126,200-square-foot Edison District office and retail building in Overland Park, Kansas. Wiegmann Associates is the mechanical contractor for the design/build project. Opus Group is the general contractor and architect.

Wiegmann Associates is furnishing and installing a high-efficiency HVAC system for the five-story building shell. Wiegmann’s HVAC solution includes a Rooftop Variable Air Volume (VAV) system with high-efficiency rooftop units, fan terminals and Variable Air Volume boxes with electric heating coils. Two large rooftop units will serve future tenant offices on the second through fifth floors. Two smaller rooftop units will serve a future food hall as well as retail tenant spaces on the first floor.

The primary project challenge is the limited rooftop space for equipment. Wiegmann is locating equipment and coordinating the shafts to leave room for significant equipment needed to serve future tenant improvement. 

Wiegmann also is designing and installing a Direct Digital Control (DDC) system using Delta Controls to allow remote access to the HVAC system through a web browser to maximize energy savings.
