ST LOUIS, MO – Wiegmann Associates has begun HVAC work as part of a redevelopment of a senior-care facility in Sunset Hills, MO. As the Engineer of Record and mechanical contractor, Wiegmann is designing and installing an energy-efficient heating and cooling system to provide optimal comfort for patients. The design/build project is expected to complete in early 2021.

Wiegmann valued engineered the original HVAC design to bring the project into budget. Wiegmann’s design solution features an energy-efficient Variable Air Volume (VAV) system to serve the 40,000-square-foot building, which features both two-story and one-story sections. The VAV units adjust the fans and compressors to match the loads in the building. This reduces the motor horsepower and compressor energy to save energy and operational costs.

The HVAC system also will meet the owner’s goal of being able to simultaneously heat and cool different spaces. It will meet the stringent standards set forth by the Department of Health and Senior Services.
