To the extent possible, the energy efficiency measures identified in the AEPS application should be verified by the meter readings submitted to the Administrator. For further discussion, please see Appendix B: Relationship between Program Savings and Evaluation Savings. Impact of Weather To account for weather differences within Pennsylvania, Equivalent Full Load Hours (ELFH) were taken from the US Department of ENERGY STAR Calculator that provides ELFH values Energy’s for seven Pennsylvania cities: Allentown, Erie, Harrisburg, Philadelphia, Pittsburgh, Scranton, and Williamsport. These reference cities provide a representative sample of the various climate and utility regions in Pennsylvania. Pennsylvania zip codes are mapped to a reference city and shown in Appendix G: Zip Code Mapping. In general, zip codes were mapped to the closest reference city because the majority of the state resides in ASHRAE climate zone 5. However, Philadelphia and a small area southwest of Harrisburg are assigned to ASHRAE climate zone 4. Therefore, any zip code in ASHRAE climate zone 4 were manually assigned to Philadelphia, regardless of distance. In addition, several protocols rely on the work and analysis completed in California, where savings values are adjusted for climate. There are sixteen California climate zones. Each of the seven reference cities are mapped to a California climate zone as shown in Table 12: California CZ Mapping Table based on comparable number of cooling degree days and average dry bulb temperatures. Any weather dependent protocol using California-based models will follow this mapping table. Table 12: California CZ Mapping Table Reference City California Climate Zone Allentown 4 Erie 6 Harrisburg 8 Philadelphia 13 Pittsburgh 4 Scranton 16 Williamsport 4 Measure Applicability Based on Sector Protocols for the residential sector quantify savings for measures typically found in residential areas under residential meters. Likewise, protocols for the C&I sector quantify savings for measures typically found in C&I areas under C&I meters. However, there is some overlap where measure type, usage and the sector do not match.
