16.02 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	133,320,631 Kilowatt-hours	454,889.99 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	0 MMBtu
Imported steam, hot water, and/or chilled water	438,513 MMBtu

Total site energy consumption, baseline year:

893,402.99 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	0.12 MMBtu per square foot	0.22 MMBtu per square foot
Baseline year	0.11 MMBtu per square foot	0.23 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:

4.47

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:

Texas Tech University uses seasonally shifting set points. New buildings are equipped with occupancy sensors and schedules for lights, AHU's are "on demand" after 9:00 P. M.

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

Approzimately 18% of Exterior lighting are LEDs. LED lights, interior and exterior, are specified for all new construction. Residence halls are approximately 50% LED.

Data source(s) and notes about the submission:

Gross floor area of building space number includes rental sites, CAM sites, abandoned spaces and unoccupied spaces. In addition, The most important consideration here is that the 10,005,766.00 ft2 is not matched to energy point of use, which should properly include only occupied square footage. That number is 9,182,788 ft2.
