Installing lighting controls is one of the most efficient means of decreasing
facility operating expenses. When lights are left on unnecessarily or areas
are lighted excessively, energy costs increase. For instance, a storage room may
be used only four or five times a day, but the lights stay on: employees with
their arms full may not be able to turn the lights off, or may simply forget.
Occupancy studies have shown that individual offices have a vacancy rate of
30% to 60% during a normal business day, but the lights may be left on 100% of
the time. Each hour that an unneeded light operates represents unnecessary
expense.
