A brief description of when and why the energy consumption baseline was adopted:

The building energy consumption baseline (2007-2008) was adopted to accurately assess future improvement made by the campus after signing the ACUPCC in 2008. Data were compiled as far back as 2005-2006, but 2007-2008 was the earliest year that was accurate and comprehensive enough to provide valuable comparisons.


Source-site ratio for imported electricity:
3.14

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.16 MMBtu / GSF 0.27 MMBtu / GSF
Baseline year 0.21 MMBtu / GSF 0.33 MMBtu / GSF

Percentage reduction in total source energy consumption per unit of floor area from baseline:
17.01
