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 32,734,535 Kilowatt-hours 111,690.23 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 121,315.30 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
233,005.53 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
2,135,957 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:

Performance year 0.08 MMBtu per square foot 0.15 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:
28.22

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:
SCU holds an annual Energy Challenge in which residence halls compete against one another to reduce their consumption of electricity over the course of a month. Winning residence halls receive special social events and prizes.

A brief description of energy use standards and controls employed by the institution:
Building thermostat set points are 74-78F for cooling and 69-72F for heating. At 11:00 PM, where building systems permit, thermostat set points are remotely adjusted to 60F for heating and 85F for cooling. Exceptions are made only for certain buildings with tighter temperature requirements. Buildings will return to their day operating mode by 7:00 AM daily.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lighting systems are currently used in 15/64 (23.43%) of buildings and 6/64 (9.375%) buildings have partial LED lighting systems. SCU has installed motion and ambient light sensors in a number of buildings. Building temperatures are controlled by a central system to ensure no unnecessary heating/cooling.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
New buildings are designed to maximize natural day lighting and utilize passive solar heating through solar chimneys and building/flooring materials that absorb solar heat and release that heat slowly to warm the space.

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

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
SCU constantly replaces high-energy consuming fixtures and devices with energy-efficient upgrades.
