We have to get fresh air into our buildings to maintain good indoor air quality and health of the residents. Recovering energy from the exhausting indoor air to temper incoming outdoor air makes perfect sense for optimizing energy usage.  

While that’s a straightforward strategy, its implementation requires quite a few critical considerations – ERV or HRV, Central or in-unit, Code and incentive program compliance, placement of the units, effect on heating & cooling loads, air sealing, filtration, insulation, and so on.

This session will discuss these aspects from a multifamily design, maintenance and constructability standpoint and share some interesting ventilation problems (with solutions!) encountered on field.
