Lighting power density (LPD) is defined as the total amount of lighting power, in watts, provided to a given floor area, in square feet. A conventional general office lighting design has an LPD around 1.2 W/ft2, while an optimized design can be 0.8 W/ft2 or below.
Wind Power Density Categories. Wind power density directly determines cost efficiency in using wind energy. We may categorize the density as poor (< 150 Watt/m2), fair (150 ~ 250 Watt/m2), good (250 ~ 350 Watt/m2), or excellent ( > 350 Watt/m2).
