Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	28,867,988 Kilowatt-hours	98,497.58 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	164,890 MMBtu
Imported steam, hot water, and/or chilled water	111,183 MMBtu

Total site energy consumption, baseline year:

374,570.58 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

164,389.35 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	July 1, 2007	June 30, 2008

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 energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	1.77 MMBtu per square meter	2.95 MMBtu per square meter
Baseline year	2.28 MMBtu per square meter	3.56 MMBtu per square meter

Metric used in scoring for Part 2

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

17.01
