368 Energy Project Financing: Resources and Strategies for Success
- Savings will be determined under post-retrofit conditions.
- The savings calculation process shown below was summarized in
the M&V Plan. - The school has provided XYZ contractor authorization to receive
energy use data from the electric and gas utility companies until
2008. - Savings are to be computed and reported monthly by XYZ contrac-
tor in a format for physical plant staff to understand and quarterly
in a format for teaching staff and students to understand. This
reporting is to begin immediately after ECM completion. It will
continue at this rate for eight years. - Annually the school will report any changes in the baseyear con-
ditions listed above, within a month after the end of each school
year. XYZ contractor will compute the energy impact of these
changes and any others that it believes are relevant and present
Non-Routine Baseline Adjustments two months before the end of
the school board’s fiscal year. - This savings determination process is expected to require a data
entry and utility bill analyst 10 hours each year and an engineer
5 hours to review reports for accuracy and establish suitable com-
putations for Non-Routine Baseline Adjustments. Total cost each
year is expected to be about $ 1,000 including reporting.
The CV (RMSE) of the baseyear models range from 5% to 18% and
are far less than the expected savings of 35% for both fuel and electric-
ity. No sampling or instrumentation error exists. Therefore the reported
savings will be statistically significant, subject to any error introduced
through non-routine baseline adjustments which may arise.
Baseyear Energy Use
The baseyear energy use for Equation 1 is taken directly from the
utility bills without adjustment. The data were tabulated in the M&V
Plan.
