About This Item


Full Description

This addendum converts requirements related to outdoor air intake location and intake protection into mandatory and enforceable language. Because outdoor contaminant sources can lead to unacceptable indoor air quality, this addendum adds requirements for minimum separation distances between common outdoor sources and outdoor air intakes. Also, because liquid water in the air distribution system can lead to microbial growth, this addendum includes requirements intended to limit the intrusion and entrainment of precipitation. To prevent contaminant related to bird nesting, this addendum requires bird screening and prohibits ledges at the outdoor air intake.
