Product Review: Heat-Recovery Ventilators & Energy-Recovery Ventilators

Tighter homes and increasingly stringent residential energy-use standards put whole-house heat- and energy-recovery ventilators in the spotlight.

Starting in 2011, all new homes built to comply with the federal Energy Star Qualified Homes standard—perhaps 200,000 units if the NAHB’s forecast for that year holds true—will be required to provide an adequate amount of controlled, fresh-air ventilation as part of a comprehensive energy conservation and indoor air quality goal.
