11.17 Btu / GSF / Degree-Day (°F)

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	34,297,590.57 Kilowatt-hours	117,023.38 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	247,156 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

364,179.38 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

2,601,699 Gross square feet

Baseline period

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

	Start date	End date
Baseline period	Jan. 1, 1990	Dec. 31, 1990

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

The building energy consumption baseline is 1990, this was adopted because this is the date that is being used for our Green House Gas Inventory, Climate Action Plan as well as various CSU system wide and state wide goals.

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.04 MMBtu per square foot	0.08 MMBtu per square foot
Baseline year	0.14 MMBtu per square foot	0.24 MMBtu per square foot

Metric used in scoring for Part 2

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

65.71

Data source(s) and notes about the submission:

The small difference between gross floor area of building space (performance year) and the gross floor area of building space reported in PRE-4 is because these numbers refer to different years. 2019 was selected as the performance because it was the most recent calendar year representative of normal operations (due to the COVID-19 pandemic). Figures in PRE-4 reflect the 2020 year, and include some additionally-constructed building space.
