Grid-purchased electricity 471,445 MMBtu 413,986 MMBtu
Electricity from on-site renewables 116.30 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) 1,148,157 MMBtu 1,079,281 MMBtu
Total 1,619,718.30 MMBtu 1,493,267 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year May 1, 2018 April 30, 2019
Baseline Year May 1, 2005 April 30, 2006

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 energy baseline reduction targets correspond to the GHG reduction targets.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 702,257.21 Gross square meters 546,299.83 Gross square meters

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.21 MMBtu per square meter 0.25 MMBtu per square meter
Source energy 0.28 MMBtu per square meter 0.33 MMBtu per square meter

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 5,700 Degree-Days (°C)
Cooling degree days 191 Degree-Days (°C)

Floor area of energy intensive space, performance year:
Floor Area

Healthcare space 4,923.77 Square meters
Other energy intensive space

EUI-adjusted floor area, performance year:
11,899,810.06 Gross square meters

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

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:

A campus-wide LED lighting retrofit was completed and replaced over 50,000 bulbs in several buildings, including outdoor street lights, parking lot lights, and pathway lights.

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

Three solar hot water heating systems have been installed.

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

A feasiblity study was completed for adding a combined heat and power gas turbine into the campus heating plant.

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):

A recommissioning program is underway for thirty campus buildings, to update heating, ventilation, and air conditioning equipment and control systems.
