Energy Savings and Persistence from an Energy Services Performance Contract at an Army Base
Abstract
This paper examined persistence of energy savings from the application of the Monitoring and Verification (M&V) for the Fort Hood Energy Services Performance Contract (ESPC). The first and second ESPC Delivery Orders (DO) were implemented for 58 buildings in 2004-2005 and for 47 building in 2006-2008, respectively. To evaluate the long-term energy savings from the first and second ESPCs, ten sites where the hourly data in 2008-2010 were available were selected, and weather-dependent and weather-independent linear and change-point linear models were calculated with the ASHRAE's Inverse Modeling Toolkit (IMT). The results show there was a considerable difference in persistence of energy savings site-by-site: varying from -352% to 677% of the audit-estimated electricity savings for the six DO#1 and four DO#2 buildings. For all ten buildings, the long-term savings were 692,987 kWh, which corresponds to 40% of the audit-estimated electricity savings.
