11.56 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	46,944,738 Kilowatt-hours	160,175.45 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	189,532 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

349,707.45 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

3,143,091 Gross square feet

Baseline period

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

	Start date	End date
Baseline period	July 1, 2005	June 30, 2006

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

This was the year before energy efficiency and carbon footprint reduction efforts began.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.09 MMBtu per square foot	0.16 MMBtu per square foot
Baseline year	0.11 MMBtu per square foot	0.21 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:

23.30

Optional Fields

Documentation to support the performance year energy consumption figures reported above:

---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

none

A brief description of energy use standards and controls employed by the institution:

We have installed energy management systems in buildings which represent 89% of our total campus building space. These systems are used in conjunction with individual building occupancy schedules to automatically turn off the HVAC systems off during unoccupied periods and perform setback of the space temperatures to 60 degrees in the winter and 80 degrees in the summer.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

We have installed LED lighting in many locations, including parking structures and our athletics complex

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

None

A brief description of co-generation employed by the institution:

None

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Retrocommissioning happens across campus, and LCA is used to evaluate equipment efficiency. The campus green fund often is used to support procurement of more efficient equipment.
