Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 711,707 MMBtu | 491,686 MMBtu |
| Electricity from on-site renewables | 24,853 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) | 2,997,870 MMBtu | 5,619,720 MMBtu |
| Total | 3,734,430 MMBtu | 6,111,406 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):
The University of Illinois at Urbana-Champaign adopted the baseline year of 2008, after careful consideration of data availability and accuracy. Information dating back to 2005 is not very reliable.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 21,625,434 Gross square feet | 20,113,569 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 | 0.17 MMBtu per square foot | 0.30 MMBtu per square foot |
| Source energy | 0.24 MMBtu per square foot | 0.36 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 | 5,527.50 Degree-Days (°F) |
| Cooling degree days | 1,367.80 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 1,760,708 Square feet |
| Healthcare space | 84,225 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):
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LEDs are in use at KCPA, Talbot Lab, ARC, ESB, McKinley and other buildings
A variety of types of LEDs are in place including downlighting, exterior canopy lighting and wall packs.
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):
Campus burns natural gas and coal to create steam for most energy needs on campus. These boilers have electric turbines attached to them so that the steam co-generates electricity that can offset the purchase of additional electricity for campus.
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):
The retrocommissioning process on the Urbana campus is focused on reviewing and improving building mechanical systems, while maintaining or improving occupant comfort.
Overview
Engineers undertake a thorough investigation of available building documentation, energy usage history, and similar pertinent data, while conducting meetings with building staff.
Field technicians and tradesmen gather data regarding operating conditions, sensor accuracy, equipment condition, and historic maintenance data from the field and current maintenance staff.
The composite teams discuss findings and then look to restore mechanical systems to their original design while implementing energy saving improvements.
The teams take the lead in making small changes and recommending larger capital projects, which require more funding, to Engineering or Maintenance for augmenting and sustaining the building's energy saving strategies.
Building system control experts implement modern methods of control, monitor energy usage after changes, review actual metered data, and verify the savings.
