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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 67,585.50 MMBtu 89,349 MMBtu
Electricity from on-site renewables 1,639.60 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) 110,918 MMBtu 155,081 MMBtu
Total 180,143.10 MMBtu 244,430 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, 2009 June 30, 2010

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):

Baseline year immediately preceeds insitutional adoption of comprehensive energy conservation program including focus on behavior & operations, installation of solar pv array, and multiple campus retrofit projects. Also preceeds addition of staff positions in engineering and sustainability that have impacted internal cpabilities. The selected baseline allows for measuring progress yielded from these changes.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 2,306,175 Gross square feet 1,977,486 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 0.08 MMBtu per square foot 0.12 MMBtu per square foot
Source energy 0.14 MMBtu per square foot 0.22 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 3,771 Degree-Days (°F)
Cooling degree days 1,071 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 35,983 Square feet
Healthcare space 2,303 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2,815,632 Gross square feet

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

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):

Energy policy includes broad university and specific department wide expectations, but also specifies expectations for individual actions, including turning off computers/monitors/printers in work spaces nightly. Regular audits are performed during unoccupied times and notes are left to individuals who have left items on. Since 2012 we have held a student energy conservation contest, and in 2016 added a faculty staff competition. Both create awareness through positive messaging and friendly competition. Energy program staff speak regularly at departmental staff meetings, and student fora ranging from orientation for Residential Advisers to environmental science classes. Energy information and reminders are shared regularly through social and campus media and annual targeted poster campaigns, and an energy conservation "tool box" is available for check out at the main library.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

nightly shutdowns in nearly all buildings (excepting residences) and greater shutdowns during holidays and summer months. All hot water setpoints are adjusted for outside air temperature and all buildings have outside air lockouts for heat. The central chiller is carefully managed to remain off as much as possible. Vacancy and daylight harvesting sensors for lighting are employed in newly renovated/constructed buildings

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

Lighting has been renovated to LED in the main campus gym, a the tennis center, the concert hall and main theater, and in all new and replacement outdoor lighting. All lighting in newly renovated dorm and brand new student housing village is LED. Vacancy sensors are standard and ligt harvesting sensors were employed in a recent renovation at the School of Law. Lighting in public spaces in may large buildings is controlled through central EMS and programmed according to the building's daily occupancy. Outdoor lighting is controlled by photocell and regularly audited for malfunction.

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 2011, seven major campus buildings have been retrocomissioned, the central chiller plant has been optimized, a comprehensive campaign to insulate steam pipes campus wide has been launched.
