University of Massachusetts Net-Zero Building

Crotty Hall
Amherst, MA

Cornerstone was hired to provide commissioning services for the design and construction of this net-zero energy building. Crotty Hall houses the University of Massachusetts’ economics graduate department, and has 35 offices and three conference rooms. It was designed to produce as much energy as it needs to consume. The three-story building draws electrical power from a rooftop solar panel array. Eight geothermal wells provide heating and cooling via water source heat pumps and an energy recovery unit air handler.

Cornerstone worked within a condensed commissioning schedule and helped remediate challenges with control sequences to ensure the building performed as designed.
