You may be using more light than you need in areas near
windows, as well as in hallways and unoccupied space. You can remove lamps based
on your own best judgment, or use a light meter that will give you readings in
footcandles (Table 12).
Table 10 gives
you an idea of how much you can save by removing even a few 40-watt fluorescent
lights. Note that multiple lamps are wired in pairs, meaning that both lamps
will stop working when one is removed.
On four-lamp fixtures, take out the two outer or inner lamps.
If you can eliminate large numbers of fluorescents, experiment with different
patterns for the best aesthetic effect.
