Side-by-Side Testing of Commercial Office Lighting Systems: Two-lamp Fluorescent Fixtures
Abstract
Lighting systems in commercial office
buildings are primary determinants of building
energy use. In warmer climates, lighting energy use
has important implications for building cooling loads
as well as those directly associated with illumination
tasks. To research the comparative performance of
conventional and advanced office lighting systems,
Florida Solar Energy Center (FSEC) set up the
Lighting Flexible Test Facility (LFTF) which allows
side-by-side comparison of lighting options in two
otherwise identical 2.7 m x 3.7 m (9' x 12') south
facing offices.
The ceiling of the LFTF contains 0.61 m x
1.2 m (2' x 4') recessed fluorescent fixtures designed
to be easily changed. Differing lighting systems were
comparatively tested against each other over weeklong
periods. Data on power consumption (watts),
power quality (power factor), work-plane interior
lighting levels (lux), bulb-wall, fixture and plenum
temperatures were recorded every 15 minutes on a
multi-channel data logger. This data allows realistic
analysis of comparative lighting system performance
including interactions with daylighting.
