Total 379,649.43 MMBtu 516,545.50 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2015 June 30, 2016
Baseline Year July 1, 2007 June 30, 2008

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

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

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 4,294,970 Gross Square Feet 3,647,900 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.09 MMBtu / GSF 0.14 MMBtu / GSF
Source energy 0.19 MMBtu / GSF 0.26 MMBtu / GSF

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

Degree days, performance year (base 65 °F / 18 °C):

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

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 (e.g. building temperature standards, occupancy and vacancy sensors):

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, e.g. combined heat and power (CHP):


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

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