The goals of this project
are to co-fund the development of bi-level stairwell
fixtures with the New York State Energy Research and
Development Authority (NYSERDA) and to determine the
energy savings, demand reduction and safety code acceptability
of occupancy-based standby lighting in California.
The
stairwell lights will use built-in ultrasonic occupant
sensors to control the lights so that stairwells are
lit to full brightness only when the stairwell is occupied.
The occupant sensor automatically reduces the lights
to a low-power consuming "stand-by" level when the space
is unoccupied. Savings are estimated to be up to 75
percent in a typical high-rise commercial building depending
upon occupancy patterns.
The
International Facility Management Association (IFMA)
and Lawrence
Berkeley National Laboratory (LBNL)
are leading the research and development work for this
project.
This project meets the PIER Goal of Improving the EnergyCost/Value of California's Electricity by reducing the energy demand from safety and standby lighting in commercial buildings. The overall objectives of this project are to assist in the development, of bi-level lighting fixtures and install and monitor bi-level fixtures in a variety of commercial buildings in California.
This project will determine and document the "real world" performance and provide data that can be used for development of building energy codes for California and convince commercial building owners and operators that this technology is ready for widespread application in California. |

Information for Bi-Level
Stairwell Fixture Performance

The objectives of this project are to:
- Identify suitable commercial buildings to serve as test facilities, working with IFMA members in California for the field test program.
- Establish pre- and post-installation conditions at each test building.
- Collect 3 to 6 months of monitored performance data for baseline and post-installation conditions at each test building.
- Analyze the monitoring data to document performance of the bi-level fixtures for any safety code, building code, or energy code compliance issues.
- Report performance data to building owners and operators, code officials and others in California.
