Energy (kWh) and demand (kW) savings will be calculated using Equation 3-2 and
Equation 3-3, respectively.
Equation 3-
2
:
kWh Savings =
∑u [ (kW UsageGroup
U,baseline
- kW UsageGroup
U,post
)
x Annual Hours
of Operation]
Equation 3-
3
:
kW Savings =
∑u [(kW UsageGroup
U,baseline
- kW UsageGroup
U,post
) x
Coincidence Factor]
where:
kWh
Savings
=
kilowatt-hour savings realized during
one year post-installation
kW Savings
=
Coincident
kilowatt demand saving
realized
kW UsageGroup
U,baseline
=
Lighting baseline demand for usage
group u
kW UsageGroup
U,post
=
Lighting demand during post-
installation
period for usage group u
Annual Hours of Operation
=
Annual number of operating hours for
the usage group u
Coincidence Factor
=
Maximum percent of lighting
operating during
at time building peak
electrical demand, as determined from
metered data from time-of-use loggers
The annual cost savings will be determined using Equation 3-4.
Equation 3-
4
:
Annual Cost Savings = [Rate

× kWh

] + [12
× Rate

where energy rates are outlined in Table 2-1 in Section 2.2.
As described
in the Responsibility Matrix, no alterations or renovations to the office
spaces are anticipated for the duration of this delivery order. Should the GSA make any
improvements, it assumes the risk that the savings calculated
by this plan may not
materialize.
