Verifying the energy savings
Options overview – Option A – Option B – Option C – Option D
Option C

Option C determines savings by studying overall energy use in a facility and identifying the effects of lighting projects from changes in overall energy use patterns. Option C methods are required when measuring interactions between energy systems (e.g. lighting/cooling) is desired, and when determining the impact of projects that cannot be measured directly. Option C usually involves a continuous measurement of whole-facility baseline energy use and electric demand, and a continuous measurement of the whole-facility energy use and demand post-installation. Energy consumption under Option C is calculated by developing statistically representative models of whole-facility energy consumption, or electric demand (i.e., kW).
