ENERGY STAR
Specifications, version 2
ENERGY STAR
INDOOR AIR PACKAGE
INDOOR AIR PACKAGE
April 19, 2007
The following specifications have been developed by the U.S. Environmental
Protection Agency (EPA) to recognize homes equipped with a comprehensive
set of Indoor Air Quality (IAQ) features. Homes that comply with these
specifications and are verified with a completed Indoor Air Package
Verification Checklist (separate document) can use the "Indoor Air
Package!' as a complementary label to ENERGY STAR for homes. Only
ENERGY STAR qualified homes are eligible for this label.
These specifications were developed with significant input from external
sources, based on best available science and information about risks
associated with IAQ problems, and balanced with practical issues of cost,
builder production process compatibility, and enforceability. EPA may
change these specifications as more information becomes available.
The construction practices and technical specifications that comprise the
ENERGY STAR Indoor Air Package are designed to contribute to improved
IAQ in new homes compared with code-built homes. However, these
measures alone will not guarantee that homebuyers will not experience IAQ
problems in their homes. Rather, the Indoor Air Package should be viewed
as a way to reduce the likelihood of experiencing such problems. For
example, homeowner behavior may negatively impact the home's IAQ and the
performance of the measures specified in the Indoor Air Package.
