From the electronic CBECS sample, one can extract operating hours per week, floor area per building, total electric consumption, total electric expenditures, and other relevant parameters.
The analysis calculates implied electricity prices by dividing total electric expenditures by total electricity consumption (the calculation of electricity price from the CBECS utility billing data implicitly includes the demand charges common in commercial buildings).
Work on a new edition of CBECS is currently underway and, barring any unforeseen significant funding reductions, is expected to be released in 2014.
He added, "Given the Energy Information Administration's (EIA) defunding of the CBECS database which supports the Energy Star rating system, the market is beginning to turn to industry-sponsored benchmarking resources, particularly as more cities and states implement energy benchmarking and disclosure regulations.
CBECS is part of the Energy Information Administration (EIA) which is under the DOE.
To make for the fairest comparison we paired each LEED building with a single matched CBECS building.
Several recent widely publicized papers compared the metered energy consumption of LEED-certified buildings with CBECS and Energy Star data, which are based on statistically significant samples of metered data from all existing buildings of any age, almost none of which comply with ANSI/ASHRAE/ IESNA Standard 90.
It rates a building on a scale of 1-100 and benchmarks it against the performance of existing building stock represented in CBECS.
