Note(s): Commercial building energy benchmarks are based off of the current stock of commercial buildings and reflect 2004 ASHRAE 90.1 Climate Zones. They are designed to provide a consistent baseline to compare building performance in energy-use simulations. 'Post' refers to buildings construction in or after 1980. 'Pre' refers to buildings construction before 1980. The benchmark building had 24,683 square feet and 1 floor. Benchmark interior lighting energy = 37.28 thousand Btu/SF. Interior equipment energy consumption = 7.63 thousand Btu/SF.
