Process for Estimating Outdoor Lighting Operation.
The
following steps define the process for estimating outdoor
lighting operation using the form shown in Table 8:
a) Complete an inventory of lighting including lamp
type, quantity, and hours of operation during the time period
being considered.
b) For each lamp type and size, identify the total
wattage draw from Table C-1 in Appendix C.
c)
Calculate energy consumption per Equation 1.
d) Sum all energy consumption values to derive total
installation exterior lighting consumption.

Electric Transmission and Distribution Losses. The
transmission and distribution losses associated with all energy
production and supply systems must be accounted for separately if
an accurate allocation of energy is to be made. The
determination of whether this energy use is to be allocated among
buildings or ships is left to each user and can be appropriately
accounted for in the reconciliation process. In some cases,
analysis of these losses may already have been done by
installation personnel or outside contractors. If these values
are considered current, they may provide the best estimate of
these losses. Estimated losses between 3 and 10 percent of total
electricity consumption have
