Example Measurement & Verification Plan for a Super espc project

6.1 
Example M&V Plan 
chiller could not take advantage of reduced condenser water temperatures because of 
physical operating limitations. 
5.3 Proposed Energy and Water Savings Calculations and 
Methodology 
The energy and demand savings will be calculated using Equations 5-7 and 5-8, 
respectively. 
Equation 5-7 
Energy Savings (kWh) = 
Σt (kWh
t
,
baseline, est
– kWh
t
,
measured, post
) 
= 0.25 
× Σt (kW
t, baseline
–kW
t,measured post
) 
Where: 
kW
t,baseline 
=
demand that the baseline chiller would have used 
under the load conditions encountered for 15minute 
interval t in the post-installation period 
kW
t, measured, post 
=
measured demand of the new chiller during 15­
minute interval t. 
Equation 5-8 
Monthly Demand Savings (kW) = MAX(kW
t,baseline
) – COINCIDENT(
kWt,post
) 
Where: 
MAX(kW
t,baseline
) 
= 
maximum monthly demand of baseline 
chiller predicted for each 15-minute interval 
in the peak period (between noon and 6 p.m. 
weekdays, May through October) during the 
current month using the model developed 
for the baseline chiller.
COINCIDENT(kW
t,post
) 
=
measured demand of the new chiller during 
the period when the predicted baseline 
chiller demand was at its maximum value.
Annual cost savings will be calculated using Equation 5-9. 
Equation 5-9: 
Annual Cost Savings = Energy Savings (kWh) * Rate
kWh
+ 
Σmonth(Monthly Demand Savings * Rate
kW
) 
where the rates are detailed in Table 2-1 in Section 2.2.
