Total energy consumption, performance year:
102,638.53 MMBtu

Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 0 Kilowatt-hours 0 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 8,336 Kilowatt-hours 28.44 MMBtu

A brief description of the certified/verified sources of clean and renewable electricity:


A brief description of the on-site renewable electricity generating facilities/devices:

We have a 5kw PV array on the rooftop of Kelley Hall, which roughly supplies 8% of the building's electricity.

Clean and renewable thermal energy (report MMBtu):
Clean and renewable stationary fuels used on-site to generate thermal energy 692 MMBtu
Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources 0 MMBtu

A brief description of the clean and renewable stationary fuels:

The new Paul M Rady building has 72 geothermal wells dug 280 feet into the earth provide temperature control, only requiring supplemental heating about six days per year. 692mmbtu is the amount of energy produced solely for February and march of 2022.

A brief description of the certified/verified sources of clean and renewable thermal energy:


Unbundled renewable energy products (report kWh):
kWh MMBtu
Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party 0 Kilowatt-hours 0 MMBtu

A brief description of the unbundled renewable energy products:

We used to have a contract to purchase RECs every year and wind power delivered through the city of Gunnison's municipal electric company. However we recently reallocated these funds to support a major solar project in partnership with the City of Gunnison at the local airport. It is estimated to open this fall (2022) and Western will receive 1/3 of this energy. Western has a renewable energy fund that students contribute to in order to purchase renewable energy for campus.

Total clean and renewable energy generated or purchased:
720.44 MMBtu

One of our LEED buildings has a small solar PV array that generates roughly 40 kWh per day or ~ 14 MWh per year; this is not included in the #s above.

energy intensive spaces include the theater spaces and labs.
