Heat-recovery ventilation

Heat-recovery ventilation

To reduce energy costs, new homes have been built to be airtight when doors and windows are closed. But indoor air quality can be compromised by pollutants, moisture, and emissions without sufficient ventilation. Heat-recovery ventilators solve this problem by using a heat exchanger to transfer heat from outgoing heated indoor air to incoming fresh air without mixing the airstreams. The heat-exchange core of a typical HRV is made up of thin aluminum passages with incoming and outgoing airstreams flowing in alternate passages.

Some of the sustainable building principles incorporated into the buildings design include using natural materials, natural ventilation, daylighting, heat-recovery ventilation, infrastructure for future solar installations, rainwater catchment and micro-hydro electrical production, as well as brownfield restoration, open space and development density credits.
Three elements distinguish passive houses from typical houses: high levels of insulation, with walls up to 12 inches thick; a carefully sealed building envelope with minimal air leakage combined with efficient heat-recovery ventilation for superior indoor air quality; and high-performance windows-typically triple-paned.
