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 12,906,263.78 Kilowatt-hours 44,036.17 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 263,673 MMBtu
Imported steam, hot water, and/or chilled water 10,522 MMBtu

Total site energy consumption, baseline year:
318,231.17 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
4,124,730 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 29, 2006

A brief description of when and why the energy consumption baseline was adopted:
The baseline is when the university first started reporting.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.09 MMBtu per square foot 0.15 MMBtu per square foot
Baseline year 0.08 MMBtu per square foot 0.10 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:
0

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:
Students learn about individual behavior changes in a class called Sustainability As A Lifestyle. They also learn about best practices in housing during the energy competitions, and throughout the year at various sustainability education events.

A brief description of energy use standards and controls employed by the institution:
University uses a BMS (Building Management System) for controlling startup, shutdown, setback, occupied and non-occupied temperature set points.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The university has been researching and installing LED lighting for the past 5 years. To date we have installed LEDs into several buildings, some tied to motion sensors. For exterior lighting the university has invested over .5 million dollars into installing over 800 LEDs for parking ramps, lots and street lighting.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Solar panels on the roof of an athletic building capture solar energy to help heat the water source in the locker rooms.

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

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Recommissioning is done on a case by case basis. It is done by troubleshooting mainly and is not a stand-alone program. However the university has recommissioned some buildings by a third party to provide some energy conservation measures.
