Energy Audits
Fayetteville State University Energy Study, Fayetteville, NC
Project Description: ASHRAE Level III Energy Study and energy modeling services for 18 campus buildings including administration buildings, classroom buildings, auditoriums, science labs, gymnasiums, and an events center, totaling 836,000 ft2. In addition to ECM evaluation, this current project involves short-term monitoring of systems to identify opportunities and assist with baseline development, and creation of calibrated Trane Trace energy models. The results of this effort will be used in the development of an energy savings performance contract.
