70.49 Btu / GSM / Degree-Day (°C)

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	12,826,927 Kilowatt-hours	43,765.47 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	133,596 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

177,361.47 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

126,070.86 Gross square meters

Baseline period

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

	Start date	End date
Baseline period	Jan. 1, 2008	Dec. 31, 2008

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

---

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	1.18 MMBtu per square meter	1.85 MMBtu per square meter
Baseline year	1.41 MMBtu per square meter	2.10 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

11.83

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:

We've expanded electrical metering to all dorms and run energy conservation competitions a few times a year.

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

Temperature settings are centrally controlled by Facility Services. In 2009, we instituted a new energy-saving HVAC policy as well. During the academic year, academic buildings and public spaces like the Warch Campus Center will be maintained at a target temperature of 68 degrees (+/-2 degrees). In the summertime, academic buildings will be maintained at a target temperature of 76 degrees (+/-2 degrees).

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

LED light replacement is now a routine part of building upgrades and renewal. All new exterior lighting is LED.

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:

We have commissioned an energy audit and building envelope study and have identified a number of opportunities for energy savings. We have not yet implemented any of these.
