At the simple inputs level of modeling, users are asked to
specify the number of fixtures per room. The model then estimates the energy
consumption per room, using default values based on the appropriate room (see table below), derived from a Tacoma Public Utilities Study (Jennings et al. 1997;
Tribwell and Lerman 1996). Where these default data are used, all fixtures in
the room are considered to be identical. Alternatively, at the detailed inputs
level of modeling, users are able to enter lamp type, number of lamps/fixture,
total fixture wattage and usage individually for every fixture.
