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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 494,164 MMBtu 610,871 MMBtu
Electricity from on-site renewables 2,747 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 673,324 MMBtu 686,768 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 76,666 MMBtu 83,978 MMBtu
Total 1,246,901 MMBtu 1,381,617 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2008 June 30, 2009

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):

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 8,499,923 Gross square feet 6,707,796 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 0.15 MMBtu per square foot 0.21 MMBtu per square foot
Source energy 0.29 MMBtu per square foot 0.42 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 4,994 Degree-Days (°F)
Cooling degree days 925 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 920,400 Square feet
Healthcare space 0 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
10,340,723 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
20.37 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):

An energy strategy plan is currently in development, outreach to school-based stakeholders is underway to strategize messaging to motivate school level behavior to reduce energy intensity.
Two undergraduate sustainability ambassadors (interns) focus on energy intensity in the University's res halls and work to implement annual outreach campaigns to reduce usage.

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

Almost every building on campus uses Direct Digital Control to automatically keep HVAC systems within a seasonal-specific and occupancy-based temperature range. Additionally in 2011, the University adopted a temperature set point policy of 68-72 degrees: 68 for winter, 72 for Summer with a two degree range on both.

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

Common spaces - stairwells, hallways, elevators, classrooms - wherever LEDs can affordably be installed - are systematically converted with 75% of academic campus buildings completed while 95% of garages have been converted to LED through an Illumination Purchase Agreement (IPA). Additional LED lighting is used in external / outside lighting applications. Additionally, all vending machines on campus are fitted with LED lighting.

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):

The University does have a retro-commissioning strategy plan. A new building audit prioritization tool and system is being employed with focuses on 5-10 buildings per year based on work order data, building energy intensity and cost of operation.
