This Standard Protocol provides the methodology for estimating savings from non-residential lighting retrofits. Savings for two savings periods are defined. The first is the remaining useful life (RUL) of the existing system, for which the baseline is the existing system. The second is the balance of measure life (i.e., post-RUL), for which the baseline is the current market average system efficiency.
The ex ante method relies on un-metered estimates of hours of use and controls savings fraction. The ex post method, which should be applied to a sample of sites, requires metering of hours of use and requires metering to determine controls savings fraction if a programs savings from controls are expected to be more than 5% of the total lighting program savings.
This measure was most recently updated in January 2019 . Updates were primarily to assumptions around the current practice baseline and the methodology for determining current practice watts.
There is a separate Code-Compliant Standard Protocol for projects subject to a code baseline.
