Basis for Cost Assumption
The decision to renovate an existing building
(versus new construction) is outside the scope of
this study. However, many GSA projects do
involve building renovation, and in these cases it is
assumed that this credit can often be achieved.
The extent of building preservation will likely be
determined by the functional requirements of each
project; i.e., the LEED objectives would not
typically override these criteria, although they
