"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 155,563 MMBtu 169,536 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) 338,742 MMBtu 369,326 MMBtu
Total 494,305 MMBtu 538,862 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Jan. 1, 2017 Dec. 31, 2017
Baseline Year Jan. 1, 2005 Dec. 31, 2005

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):
2005 was the last complete year that we have data from before the current campus sustainability plan was completed.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 2,794,717 Gross square feet 2,880,936 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 0.18 MMBtu per square foot 0.19 MMBtu per square foot
Source energy 0.30 MMBtu per square foot 0.31 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 5,631 Degree-Days (°F)
Cooling degree days 799 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 135,557 Square feet
Healthcare space 7,318 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
3,131,720 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
24.55 Btu / GSF / Degree-Day (°F)

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):

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Smart thermostats were installed in all buildings to better regulate heating and cooling during December 2016 through April 2017. Building automation control system was retrofitted to provide additional data to building maintenance which increased their ability to quickly diagnose and fix problems.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
During 2017 self-contained and self-powered LED streetlight units were installed to provide light in a parking lot. Each is powered by wind and solar energy which is stored in batteries contained within each pole and are outfitted with communications antennae which communicate from one unit to the other. The units can also be remotely set to adjusted brightness levels.

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

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):
Since 2014 IIT Tower (the largest building on the Mies Campus) has participated in RetroFit Chicago, updating systems to decrease energy usage by 20%. Retrofitting of Wishnick Hall, in the process of achieving Leed Gold certification, decreased energy use dramatically.
