Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 66,662 MMBtu 75,357 MMBtu
Electricity from on-site renewables 1.80 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) 117,910 MMBtu 77,105 MMBtu
Total 184,573.80 MMBtu 152,462 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, 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):

Washtenaw Community College was seeking to reduce the energy consumption and greenhouse gases generated by the campus and committed with an assessment that was performed by an contracted employee and this became our base of measurement. Our then President signed the ACCUPC climate commitment pledge.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 1,201,820 Gross Square Feet 989,275 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 / GSF 0.15 MMBtu / GSF
Source energy 0.27 MMBtu / GSF 0.32 MMBtu / GSF

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):

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):

Washtenaw Community College has a standard for space temperature set points that are as follows: Winter season heating during occupied times is 72 degrees and during unoccupied times is 64 degrees. Summer season cooling occupied time is 76 degrees and during unoccupied time is 82 degrees.

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

Washtenaw Community College has widely adopted the use of LED fixtures across the campus. Most all exterior lighting poles on main campus are LED. The main campus theather house lights are LED. Multiple high bay areas are converted to LED.

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

Washtenaw Community College has operated a geothermal heating and cooling system in the Occupational Education building since the installation in 2011. The system provides the heating and cooling for approximately 125, 000 g.s.f. of building.

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

Washtenaw Community College has recently installed two 65KW micro turbine units that generate electricity, heating water, and cooling water.

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):
