Project 4.1 Hotel and Institutional Bathroom Lighting - Goals and Objectives


The goal of this project is to develop two energy efficient bathroom lighting technologies using a two-phased approach that will save energy and improve safety in hotel bathrooms and related institutional applications.

Lawrence Berkeley National Laboratory (LBNL) is leading the research and development work for this project.

The economic goal for the first technology is to achieve 50 to 75 percent energy savings over the estimated base case use and have a three-year payback period. In the second system, the goal is also to achieve 50 to 75 percent energy savings. The payback as a function of energy in this second system will be longer, but this increased payback will be mitigated by a first cost reduction in installation costs.

Project Objectives include:

  • Develop and test two energy-efficient hotel/institutional bathroom lighting systems: a hotel bathroom lighting retrofit (Phase 1) and a hotel bathroom light "smart" fixture for new hotel construction and major renovations (Phase 2).
  • Develop quantifiable methodologies and collecting monitoring and survey data to properly evaluate the operation of these systems for both Phase 1 and 2.
  • Document a 50 percent energy savings over the base case energy in hotel bathrooms for both Phase 1 and 2.
  • Improve cost effectiveness of hotel bathroom lighting technology by making bathroom fixture installation more efficient and reducing overall costs. (Phase 2).

Project Information for Hotel and Institutional Bathroom Lighting

The installation of controllers for retrofit applications in approximately 400 rooms at the Sacramento Doubletree Hotel is complete - view Press Release.

This project meets the PIER Goal of Improving the Energy Cost/Value of California's electricity by developing a hotel bathroom lighting retrofit system in Phase 1 that will achieve 50 to 75 percent energy savings in the hotel/institutional bathroom. Phase 2 of this project also meets PIER's goal of improving the value of California's energy by developing a complete hotel/institutional bathroom lighting system that is easily installed and also achieves 50 to 75 percent energy savings over the conventional base case system.This project also meets a secondary PIER goal of increasing the reliability of the electric system by reducing peak load demand.
