Hotel Guestroom Controls Study

Project Number PGE 0801 Organization PG&E End-use Whole Building Sector Commercial Project Year(s) 2008 - 2010

Project Summary:


In the hospitality industry in the United States, card keys are used almost universally to gain entry to guestrooms and other areas of hotels.such as swimming pools, exercise rooms, and laundry areas but not as part of energy management systems. The investigators studied the literature on potential energy and demand savings from card key control systems in Report #0609 derived from field observations as well as computer simulations based on those observations. In addition, they surveyed hotel guests for their perceptions of card key controls.

The study monitored HVAC systems, lighting equipment, and occupancy patterns in four rooms in each of the two hotels. Because of the small sample and the ability of guests to override controls, they used computer simulations based on observed occupancy patterns to calculate annual results for San Francisco and to expand the results to four other climates within Pacific Gas and Electric Company's (PG&E) service territory.
