Baseline Year July 1, 2006 June 30, 2007

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

FY07 was adopted as the preferred baseline year for STARS data reporting as it represented consistent data availability across the majority of credits.
