1In December 2005, EPA completed the installation of a new, Web-based advanced metering system at the Main Building and National Computer Center (NCC) in an effort to improve the quality of reported energy data and enhance overall energy management. Instead of immediately transitioning to the new advanced metering data for reporting purposes, EPA undertook a phased approach in order to ensure the integrity of the new data stream and to determine the most appropriate method for normalizing historical energy data previously reported using engineering estimates. As a result, at the outset of FY 2006, EPA reported energy consumption for the Main Building and NCC using the engineering estimates used since FY 2003 until the new advanced metering data was online for a full year. As part of its phased approach, EPA initiated a comprehensive analysis and adjustment of historically reported FY 2003–FY 2006 energy consumption data for the Main Building and NCC. In FY 2007, EPA synchronized historical energy consumption data using a single consistent methodology for each reported energy commodity during the FY 2003–FY 2006 period. In December 2008, EPA completed a comprehensive, two-phase adjustment of historical energy consumption data at EPA's RTP campus, which allowed the Agency to transition from deriving energy data from engineering estimates to using data from RTP's advanced metering system. This enabled EPA to more accurately evaluate the energy performance of EPA's largest campus.
