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.
