11.09 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	62,500,031 Kilowatt-hours	213,250.11 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	320,170.50 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

533,420.61 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

3,647,900 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, 2007	June 30, 2008

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

This is the standard baseline date for sustainability reporting at Loyola.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.09 MMBtu per square foot	0.18 MMBtu per square foot
Baseline year	0.15 MMBtu per square foot	0.26 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:

31.55

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

Loyola has undertaken a number of energy related initiatives on all campuses. Specifically an annual program titled 'EnergyWeek' takes place each fall to engage the community on energy impacts and opportunities.

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

Loyola's Information Commons uses a Building Automation System (BAS) that divides the seasons into Winter and Summer and monitors indoor and outdoor conditions to react accordingly. In Winter (whenever the the temperature falls below 55 degrees Fahrenheit), space is maintained at approximately 71 degrees. In Summer, the air handlers turn off and windows open when the temperature is between 55 and 68 degrees. When the temperature is above 74 degrees, the air handlers start circulating air.

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

Loyola is upgrading many of its buildings with energy-efficient technologies, such as energy management systems, heat recovery systems, LED lighting, and lighting sensors. Recently, Loyola completed a major conversion from HID to LED for outdoor lighting fixtures across campus.

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

Loyola has the largest geothermal installation in Northeastern Illinois at the Institute of Environmental Sustainability.

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:

We have many retrofit programs underway and a recommissioning of the Quinlan Life Science Building.
