The limits are provided for whole buildings or individual space types as Lighting Power Densities (LPD) expressed in watts per square foot (W/ft2). The LPDs in Standard 90.1 are based on standard T8 lamps and electronic ballasts. Even
Parking Structure Lighting Guide - Energy
www.energy.govLighting Power Density (LPD) Lighting power density (LPD) is the total input power (i.e., including the driver or ballast) multiplied by the total number of luminaires divided by the area in which the equipment is installed. Many energy codes use this metric, however; it does not actually focus on energy. Energy is power multiplied by time, so ...
