The minimum sample sizes and precision of results are different <br />depending on the number of fixtures included in the project. The most common fixtures will have a high <br />degree of certainty in the results, while the least common fixtures will have greater uncertainty in order to <br />ensure measurement costs are commensurate with performance risk. Three different classes of <br />measurement requirements are included: <br />1. Fixture types with less than 20 total fixtures will not be measured. The power shown in the table <br />below will be used in all calculations. <br />2. Fixture types with 20 — 100 total fixtures will have at least 4 measurements taken. Measurements <br />will continue to be taken until the 90% confidence interval for the true population mean spans no <br />more than 10% above and below the mean of the sample. <br />3. Fixture types with more than 100 total fixtures will have at least 10 measurements taken. <br />Measurements will continue to be taken until the 95% confidence interval for the true population <br />mean spans no more than 5% above and below the mean of the sample. <br />The mean of each sample set will be treated as the power consumption for that fixture type for all savings <br />calculations. The preferred locations for measurements for the new retrofit types will be locations where <br />some previous measurement was taken. The number of post -retrofit samples measured is independent <br />from the number of pre -retrofit samples taken. These measurements are taken to determine the average <br />power use of each fixture type, not the reduction of power use in any specific locations. All measurements <br />will be taken using the same equipment and will be calibrated. The table below lists each fixture type to <br />be measured, the estimated power of that fixture type, the total quantity of that fixture type, and the <br />minimum amount to be measured during the post -implementation period. <br />Fixture Code <br />Estimated Power (W) <br />` Total Fixtures <br />481 <br />Minimum Sample <br />10 <br />4ft 2 Lamp 12.5W LED Tube <br />25 <br />80W LED <br />80 <br />213 <br />10 <br />4ft 3 Lamp 12.5W LED Tube <br />37.5 <br />147 <br />10 <br />4ft 4 Lam2 12.5W LED Tube <br />50 <br />94 <br />4 <br />2 5.5W LED PL-2 Pin <br />11 <br />21 <br />4 <br />32W 4ft LED Vapor Tight Fixture <br />32 <br />12 <br />0 <br />40W LED Canopy Light <br />40 <br />7 <br />0 <br />30W LED Wall Pack <br />30 <br />7 <br />0 <br />50W LED Pole Li ht-50K <br />50 <br />6 <br />0 <br />55W LED Wall Pack <br />55 <br />4 <br />0 <br />2ft 2 Lamp 7W LED Tube <br />14 <br />4 <br />1 0 <br />10W LED A19 <br />10 <br />4 <br />1 0 <br />Energy Solutions Proprietary and Confidential <br />002811 22 <br />
