Hotel Demonstrates Energy-Efficient Lighting

The hospitality industry has become one of the biggest sectors of the economy. For this reason, Lawrence Berkeley National Laboratory (LBNL) has a research program specifically dedicated to reducing energy use in hotels. By monitoring energy use in hotel rooms, LBNL found that one of the largest energy savings opportunities is the bathroom light, often left on while the guest is out of the room. Researchers suggest installing an occupancy sensor combined with an LED nightlight that often eliminates the need for an overhead light in the middle of the night.

To demonstrate and verify the LBNL research, Watt Stoppers, a Livermore, CA, company that designs lighting control systems, will supply such a lighting system and Sacramento's Doubletree Hotel will install it with the help of a grant from the Sacramento Municipal Utilities District. LBNL will then analyze use patterns. DOE's Office of Building Technologies funded the hotel lighting energy research. For more details on the target demonstration, see LBNL's press release.
