HOME Ventilation Guide Continuous Whole-House Ventilation Fans, heat or energy recovery ventilators work continuously to improve indoor air quality. A continuous, balanced ventilation system brings in fresh air from the outside while exhausting stale air from the inside. (www.hvi.org) provides information on a variety of products that can be used for continuous whole-house ventilation. It is important to choose a system appropriate for your climate. Balanced systems with both supply and exhaust air can generally be used in any climate. Exhaust-only systems are appropriate for temperate to cold climates, while supply-only systems are more appropriate for hot climates. In the early 1980s, continuous whole-house ventilation systems were developed to meet the indoor air quality needs of the tight, well-insulated homes being developed at that time. Continuous whole-house ventilation can be provided by singleand multiport exhaust and supply fans; balanced ventilators; and heat or energy recovery ventilators (HRVs or ERVs). One or more fans can be combined to supply fresh air and exhaust stale air to provide a continuous level of general ventilation throughout the home. These fans are typically very quiet (less than 1.5 sones) or are remotely located to reduce the perceived sound level in the home. Sometimes it is possible to upgrade a bathroom exhaust fan to a very quiet fan that operates all the time to provide both local bathroom exhaust and continuous wholehouse ventilation. The HVI Certified Home Ventilating Products Directory located on the HVI website Heat and energy recovery ventilators Heat and energy recovery ventilators (HRVs and ERVs) bring in fresh air from the outdoors while exhausting stale air from the home. Both HRVs and ERVs moderate the temperature of the fresh air by conducting heat from one air stream to the other. Additionally, ERVs modify the humidity content of the fresh air through the transfer of water vapor from one air stream to the other. Since HRVs and ERVs combine both exhaust and fresh air intakes, we describe them as balanced systems. The continuous fresh air that is provided conditions and improves the indoor air quality, thus increasing occupant comfort, especially for those who suffer from allergies and respiratory ailments. How they work The HRV or ERV is a combination of fans, controls and heat-recovery elements that exhaust stale air from the home, bring fresh air in from outdoors and transfer heat energy from one air stream to the 20 H V G www.hvi.org
