17.21 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	133,237,452 Kilowatt-hours	454,606.19 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	867,411 MMBtu
Imported steam, hot water, and/or chilled water	438,513 MMBtu

Total site energy consumption, baseline year:

1,760,530.19 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

8,069,783 Gross square feet

Baseline period

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

	Start date	End date
Baseline period	Sept. 1, 2009	Aug. 31, 2010

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

---

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.13 MMBtu per square foot	0.24 MMBtu per square foot
Baseline year	0.22 MMBtu per square foot	0.34 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:

29.27

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

---

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

The University has a goal of reducing the EUI by 2% annually. We utilize the eSight Energy Management System to monitor building performance and
investigate deviations from the standard of operation of the HVAC equipment. All eSight buildings are checked on three times/day, Monday thru Friday to
maintain vigilance over building operations.

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

All new construction and renovation work includes LED luminaires, and any failed luminaire is replaced with an LED equipped equivalent.

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

A small geothermal system is installed at the Administration Support building.

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

Lubbock Power & Light operates a sub-station adjacent to the campus that sends steam to the CHACP at no charge. The operation of the sub-station is
intermittent, and has decreased over the last two years.

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

Create a five-year plan for energy efficiency projects.
