The equipment used to heat or cool a building often generates heat as a by-product of the HVAC work.  This heat generally escapes when fresh air is brought into the building.  A Heat Recovery Wheel recovers that heat that would escape to the outside, and uses it to make the entire HVAC system more efficient. 

Air-to-air heat recovery systems are required by the university’s Facilities Standards for new capital projects. As a part of the LEED certification and deferred maintenance process, heat recovery wheels have been installed in multiple facilities on campus.
