Energy Star indoor air package

Energy Star indoor air package

An EPA (U.S. Environmental Protection Agency) program to promote the construction of new homes that are less likely to have indoor air problems than conventional homes. Homes complying must meet Energy Star Homes requirements as well as additional specifications addressing indoor air quality. Among the program’s requirements are details designed to limit water entry into basements, requirements for radon mitigation components in geographical areas with potential radon problems, a requirement for sill pan flashing at window rough openings, mandatory roof gutters except in dry climates, a mandatory layer of rubberized asphalt under roof valleys, a duct-sealing specification, a prohibition against locating furnaces in garages, and a requirement for a mechanical ventilation system that complies with ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) 62.2.
