Utilizing Daylighting Controls in a Manufacturing Facility

Opportunities exist to reduce artificial lighting in
manufacturing facilities which have skylights and/or
fenestration that provide sufficient quantities of
daylight to the work space. Using photometric
sensors to measure the illuminance in the space,
artificial lights can be automatically switched off
during periods when sufficient daylight is available.
Daylighting controls used in commercial buildings
often use dimmable ballasts with fluorescent lights.
Most fluorescent lighting used in manufacturing
facilities use high output ballasts which are non-dimmable.
The preferred method for reducing
artificial lighting output is to switch the lamps off.
For multi-lamp fixtures such as six-lamp Super T8’s,
ballast/lamp configurations are either 2-4 or 3-3, thus
giving rise to various stages of lighting reduction.
This paper examines these lighting control strategies
for a 90,000 square foot manufacturing facility in
Iowa. Using the EnergyPlus building energy
simulation code, annual lighting energy savings
associated with utilization of daylighting were
computed for the building. Results showed that the 2-
4 switching control strategy provided better energy
reduction opportunity compared to 3-3 switching
control.
