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.
