States with unique energy codes were not included in the analysis because the codes in these states would be difficult to appropriately compare to ASHRAE Standard 90.1 and most of these states have energy offices that routinely assess their codes against the model codes. In states with codes prior to and including the 2000 IECC or Standard 90.1-1999, those states with no statewide energy code, and home rule states which did not specifically request that another code be used, Standard 90.1-1999 was used as the baseline for comparison.

Three DOE Benchmark buildings were used for the simulation used in this analysis: a medium office building (53,600 ft2), a mid-rise apartment building (33,700 ft2), and a non-refrigerated warehouse (49,500 ft2...

By legislation, the Maryland Building Performance Standards (MPBS) which was adopted in 1994 is updated every three years to coincide with the International Code Council (ICC) change cycle, as the ICC updates their I-codes. The MBPS adopted the 2012 International Energy Conservation Code and ASHRAE 90.1-2010 on January 1, 2012. Maryland legislation requires the State of Maryland to adopt the first printing of the latest International Building Code, International Residential Code and the International Energy Conservation Code within one year of publication by the ICC.
