Evaluating the Impact of Energy Savings Technologies in The Statler Hotel

Abstract

On average, hotels in America spend $2,196 per available room yearly on energy. In efforts to reduce energy costs, The Statler Hotel permitted Schneider Electric to test Cassia™, its energy management system. Cassia™ is an in-room energy solution based on sensors that detects room status and triggers temperature setbacks in heating and cooling units. In this study, a four-room test bed was used to evaluate potential energy savings associated with Cassia™. Statistical analyses were conducted to determine parameters’ influence in reducing energy units’ runtime. Results show that Cassia™ reduced runtime by 18%. While the average energy savings reported by Schneider Electric is 25-44%, this range includes savings from lighting, which was out of the scope of this study. By extrapolating savings from August-February 2012, a total of $7,829 would have been saved given a Cassia™ installation throughout the Hotel, while $3,003 saved solely based on vacancies during an unrented status.
