Energy & Heat Recovery Ventilation Adopted by the Government.

Energy Recovery Ventilation (ERV) Mandated by General Services Administration (GSA)

“The dedicated 100-percent outdoor air ventilation systems shall be completely independent of any other air distribution system. Building exhaust air heat recovery shall be provided to precondition the outdoor air.”

Facility Standard P100, Section 5.4

This Standard Applies To:

  • New buildings
  • Major and minor alterations
  • Work on historic structures

ERV Recommended by the Department of Energy

"[Energy recovery ventilation] systems reduce the heating and cooling peak energy demands and can reduce the heating energy consumption of buildings by 30 percent to 50 percent... Effective use of energy recovery devices results in decreased loads on the heating and cooling mechanical equipment. Equipment with reduced capacities can then be purchased. The savings gained from purchasing smaller equipment often exceeds the first cost of the energy recovery devices.”
