Practical Applications
CFC-based refrigerants are no longer available in
the United States for new HVAC&R equipment.
GSA also prohibits the use of CFCs through the
P100 standards. In addition to new buildings,
GSA's major modernization projects are expected
to comply with this prerequisite, as these projects
typically involve full replacement of existing
HVAC equipment.
Basis for Cost Assumption
The Courthouse and Office Building models both
assume all new HVAC&R equipment; therefore
the prerequisite is earned at no cost.
