Post-Im lementation Measurements and Documentation No Post -Implementation Period measurements are required. All post -project measurements will be performed during the Performance Period. Performance Period Measurements and Documentation Fi (Performance Period accuracy of water meter in flow category j) will be determined by taking samples of the accuracy of the post -project water meters. This will be completed at least 12 months after the Date of Commencement of this Contract. Accuracy will be computed by dividing measured consumption by the actual water flow during a short-term test. These tests may be performed at the meter location or at a remote testing facility. The average accuracy percentage for each class will be used as the appropriate Fi figure for each meter. The table below shows the minimum sample sizes for each post -project meter class and will be used to record the results of the measurements. There may be different numbers of pre- and post -project meter classes. ESCO may elect to perform additional measurements beyond the sample size minimums for use in determining the Fj values. The minimum sample size for each meter class will be the smaller of 10 meters and 1 % of the new population of the meter class.

Parameter Estimates Performance Period Meter Accuracy Percentage (F) Flow CateqoDl 2 Flow Cate o Flow Category K Of the parameters identified under the equations for water savings in Section B, only P/ (percent of water consumption for flow rate category j) will be estimated. Each water meter will be assigned flow rate by meter size. The table below defines the estimated Pi values for each meter size. Percents a of Water Con sum Dtion f P Catego Max. Flow Int. Flow Min.

Cost Savings Calculations Provided below are the methods and equations used to determine the cost savings associated with this particular methodology. Cost Savings are calculated as the difference between the baseline and Performance Period energy/water costs using the utility rates as defined above in Schedule D: Water/Sewer Water Rate Data. Water rates will escalate at 3% annually; sewer rates will escalate at 5% annually. The applicable water rates will be applied to the baseline and Performance Period water consumption as determined in Paragraph B for each meter. OPTION B — SOLAR PHOTOVOLTAIC A.
