Total energy consumption (all sources, excluding transportation fuels), performance year :
296433.50 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:
133.10 MMBtu

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

Lincoln Hall Solar PV Array installed in 2011. 234 panel array with peak capacity of 54kW, equivalent to about 2.9% of building’s energy demand. Dashboard: http://live.deckmonitoring.com/?id=psu_lincoln_hall. This is the only source counted in above figure.

“Living Laboratory” project in 2010 on Science Research & Teaching Center’s (SRTC) 3rd floor patio integrates green roof technology with PV at a 4.9 kW peak output. Monitoring of the various functions of green roofs and the output of the solar arrays will test the hypotheses that plants grow better with partial shade and solar panels perform better with a cooler under layer. Dashboard:http://solar.pdx.edu/home/visualizations/

PV Test Facility installed in 2008 at Cramer Hall includes five different types of solar arrays representing different technology and inverters with a 5 kW peak output. Annually, this could generate about 5,000 kWh, which is estimated to save $330 in annual utility costs. Dashboard: http://solar.pdx.edu/home/visualizations/

Campus Recreation Center uses excerise machines use ReRev technology to genderate electricty for the building.

Millar Library recently installed PV array, but it is not yet operational. The array has a peak capacity of 90kW.
