How is lighting power density determined?
A: By submetering a building’s energy use
B: By conducting energy modeling using special software
C: By calculating the energy consumption divided by the square feet in a building
D: By measuring the installed lighting power per unit area

参考答案: D

Reference: LEED 2009 for New Construction and Major Renovations Rating System

Submetering helps to measure specific energy consumption in a building.

Energy modeling can help determine a building\'s overall energy use.

C is energy use intensity.

Lighting power density is the installed lighting power per unit area (the amount of electrical power used to illuminate a space). It is usually expressed in Watts per unit of area.

Reducing the lighting power density can reduce energy use.
