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.
Approach
The approach taken in this project will be 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.
