The goal of this project
is to design, develop and prototype portable energy-efficient
office luminaires that integrate occupancy-based controls
to provide users a higher level of control and visual
quality than they currently receive from traditional
overhead lighting systems. This system is intended to
be flexible enough to be suitable for the varied demands
of a broad cross-section of office lighting applications.
Berkeley National Laboratory (LBNL) is
leading the research and development work for this project.
a technical level, this includes developing light distribution
systems that integrate user controls with high-efficiency
luminaires that provide for both task and ambient lighting
economic goal of this project is to develop a portable
luminaire which, when used as a system, will reduce
lighting energy costs by 30 to 50 percent in conventional
project meets the PIER Goal of "Improving the Energy
Cost/Value of California's Electricity" by reducing
office lighting energy costs by 30 to 50 percent while
improving lighting quality in office spaces. This project
also meets a secondary PIER goal of increasing the reliability
of the electric system by reducing peak load demand.
objective of this project is to develop portable luminaires
with integrated occupant controlled lighting technology
to give the occupant direct control over his/her lighting
system, to improve efficiency of office lighting technology
by 30 to 50 percent and to improve cost effectiveness
of office lighting technology by directing light to
the areas where it is most needed. Building-level strategies
will also be determined.
Information for Portable Office Lighting Systems
project has four key technical objectives:
1) "Berkeley Lamp II": Research and development of a
prototype, next-generation Berkeley Lamp that integrates
an occupancy sensor into a floor-based model.
Workstation Level Solutions: Research and development
of novel portable luminaires designed to provide for
all of the task and ambient lighting needs of a cubicle
or workstation in a manner that enhances energy efficiency
and visual quality.
Office-Level Solutions: Integration and controls strategies
for the luminaires developed for the workstation level that yield energy savings while providing
an appropriate overall lighting environment.
Building-Level Concepts: Investigation of broader building-wide
systems/strategies that can build on the workstation
and office-level solutions in order to achieve further
energy savings and control.
