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., Presented at the 11th International Conference for Enhanced Building Operations, Oct 18-20, 2011.
