Fresh-air Ventilation

People need to breathe. It's also important for our houses to breathe - exhausting pollutants to the exterior while delivering fresh air into our living environment. We don't want this air to be introduced into our homes through small cracks and gaps in the home's walls, floors, and ceilings. We want to have control over where this air comes from. We want the house to breathe through its lungs, not through its skin.

An ERV (Energy Recovery Ventilation) machine (example shown at RIGHT) does a very efficient job of breathing for our houses. It exhales and inhales, both removing stale air and introducing fresh air into our homes. It also recovers some of the heat and moisture from the incoming/outgoing air (depending on the season) to minimize energy loss as a result of this breathing.

Some ERV's include HEPA filters that pre-filter the incoming air before introducing it into the living environment. Systems can be ducted independently or intertie with the existing duct system. Our building performance specialists will assist you in selecting the proper unit and installation strategy.

Winter-time Example

A - Air is exhausted from the ERV to the outside, taking
     pollutants with it
B - Air is brought to the ERV from the outside, collecting
     heat & moisture from the outgoing air along the way (C)
C - Air from the house is pulled into the ERV and passes
     heat & moisture to the incoming air along the way (B)
D - Pre-conditioned air from the outside (B) is delivered into
     the house after picking up heat and moisture from the
     outgoing air (C)
