Following on the heels of NYC’s Local Law 84 (2009), D.C.’s benchmarking rules will soon need to be acted upon. Buildings over 150,000 sq feet may need to report as early as January 2013.
The basic structure of benchmarking follows the EPA Energy Star Portfolio Manager guidelines. For D.C., as in New York, we expect to find that as the sample size increases within the EPA database, the scoring can change dramatically from the benchmarked year. This is because as more buildings enter the database, the average emissions per space type can also change in the region.
