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).

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.
