Weighting Factors for the Commercial Building Prototypes Used in the Development of ANSI/ASHRAE/IESNA Standard 90.1-2010

Detailed construction data from the McGraw Hill Construction Database was used to develop construction weights by climate zones for use with DOE Benchmark Buildings and for the ASHRAE Standard 90.1-2010 development. These construction weights were applied to energy savings estimates from simulation of the benchmark buildings to establish weighted national energy savings.
