Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 194,599.28 MMBtu | 196,375 MMBtu |
| Electricity from on-site renewables | 0 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 185,050.15 MMBtu | 320,170.50 MMBtu |
| 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 per square foot | 0.14 MMBtu per square foot |
| Source energy | 0.19 MMBtu per square foot | 0.26 MMBtu per square foot |
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):
| Degree days (see help icon above) | |
| Heating degree days | 5,488 Degree-Days (°F) |
| Cooling degree days | 823 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 153,128 Square feet |
| Healthcare space | 1,500 Square feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
Documentation (e.g. spreadsheet or utility records) 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 (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):
N/A
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.
