UNCG was the first university in the UNC system to enter into a Performance Contract with an Energy Services Company (ESCO). The Investment Grade Energy Audit (IGEA) took place in 2006 and a contract was signed in 2007. Construction started in the Fall of 2007 and was completed in the Fall of 2008. We have just finished our first year of operational savings of a twelve year contract. We are expecting our first year annual savings report from our ESCO by November 30, 2009.
UNCG’s Performance Contract consisted of two new chiller replacement systems, upgrading DDC controls in four buildings, replacing T12 lighting with T8’s in approximately 7400 light fixtures, replacing over 400 HVAC building mixing boxes with VAV box upgrades, upgrading 21 building dry transformers, replacing 349 flush valves, 257 china replacements, and retro-commissioning all systems.
Relating to an environmental impact, UNCG’s project will reduce CO2 emissions by 5261 tons per year, SO2 emissions by 57 tons per year, and NOx emissions by 25 tons per year. (CO2 is the greatest contributor to greenhouse gases, SO2 is the principal component of acid rain, and NOx is a major contributor to smog and acid rain).
