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

Total energy consumption (all sources, excluding transportation fuels), performance year :
150,200.12 MMBtu

Total clean and renewable electricity generated on site during the performance year and for which the institution retains or has retired the associated environmental attributes:
221.75 MMBtu

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

The Eden Hall campus canopy, field lab, and Dairy Barn Café are combined into a 110 KW photovoltaic system with 408 panels. There are 240 on the canopy, 144 on the field lab, and 24 on the café.


Non-electric renewable energy generated on-site, performance year:
61,350 MMBtu

A brief description of on-site renewable non-electric energy devices:

All of our hot water is heated by solar thermal sources. We currently have three different solar thermal hot water systems (two on Shadyside campus and one on our Eden Hall campus). The number above is only a small fraction of the total energy produced by our solar hot water; this number only represents the solar hot water system on Fickes (a residence hall on Shadyside Campus).


Total clean and renewable electricity generated by off-site projects that the institution catalyzed and for which the institution retains or has retired the associated environmental attributes, performance year:
0 MMBtu

A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
---

Total third-party certified RECs, GOs and/or similar renewable energy products (including renewable electricity purchased through a utility-provided certified green power option) purchased during the performance year:
40,945 MMBtu

A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:

We use a Green-e Certified mix from Renewable Choice. We buy in 3-yr contracts, working forward, so we must estimate how much electric we will purchase as well. We generally over-estimate a bit, so that we don't under-buy.

A brief description of other sources of building heating not specified above:

Micro-channel solar thermal hot water systems are on our largest residence halls on our Shadyside campus. Sixty-four collectors, covering 1270 square feet, produce 90kw at peak power, with total thermal storage of 2,260 gallons. We produce significantly more energy from these arrays than the number above is portraying, but since our most accurate metering data is on our solar thermal array on Fickes (residence hall on Shadyside), that is the number represented in the space above; please note that this is the data from Fickes alone. We also have solar thermal on Woodland (Another residence hall on Shadyside campus) and at our Eden Hall campus, again, whose energy production is not portrayed in this number.


Percentage of total energy consumption from clean and renewable sources:
68.25
