4.4 – Energy Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.4-11 Methodology A brief overview of the methodology applied to assess the Project’s potential impacts is provided below: Electricity: The Project’s on-site electricity usage data were determined using California Emissions Estimator Model (CalEEMod) Version 2016.3.2. Electricity demand within PG&E’s service area was obtained from CPUC reports (specifically, the RPS Program Updates [CPUC 2019]). Electricity would be necessary for multiple purposes, including building heating and cooling, lighting, electronics, electric pump, and electric forklifts. Natural Gas: The Project on-site natural gas usage data were provided using CalEEMod. Regional natural gas demand data was obtained from CEC reports (specifically, the California Energy Demand Forecast [CEC 2018a]). CalEEMod Adjustment for Title 24: The current Title 24, Part 6 standards, referred to as the 2019 Title 24 Building Energy Efficiency Standards, became effective on January 1, 2020. The current version of CalEEMod assumes compliance with the 2016 Title 24 Building Energy Efficiency Standards (CAPCOA 2017); however, the Project would be required to comply with the 2019 Title 24 Standards. Per the CEC Impact Analysis for the 2019 Update to the California Energy Efficiency Standards for Residential and Non-Residential Buildings, the first-year savings for newly constructed non-residential buildings are 197 gigawatt hours of electricity, 76.6 megawatt of demand, and 0.27 million therms of gas, representing reductions from the 2016 Title 24 standard of 10.7%, 9%, and 1%, respectively (CEC 2018c). To take into account energy reductions associated with compliance with 2019 Title 24, the CalEEMod Title 24 electricity and natural gas values were reduced by 10.7% and 1%, respectively. The applied reductions are anticipated to be conservative because, in general, nonresidential buildings built to the 2019 standards are anticipated to use an estimated 30% less energy than those built to the 2016 standards (CEC 2018b). Petroleum: Potential impacts were assessed through projected traffic trip generation during construction and operation, as provided by the CalEEMod outputs, spreadsheet-based model and emission factors from CARB EMFAC2017 (Appendix B), and the Traffic Impact Analysis that was prepared for the Project (Appendix F). Fuel consumption from construction equipment was estimated by converting the total CO2 emissions from each construction phase to gallons using conversion factors for CO2 to gallons of gasoline or diesel. The conversion factor for gasoline is 8.78 kilograms per metric ton of CO2 per gallon, and the conversion factor for diesel is 10.21 kilograms per metric ton of CO2 per gallon (The Climate Registry 2020). Heavy-duty construction equipment associated with construction activities and vendor trucks were assumed to use diesel fuel. It was assumed that construction workers would travel to and from the Project site in gasoline-powered vehicles. Fuel consumption from worker and vendor trips was estimated by converting the total CO2 emissions from the construction phase to gallons using the conversion factors for CO2 to gallons of gasoline or diesel. The fuel consumption resulting from the Project’s operational phase would be attributable to vehicles traveling to and from the Project site. Similar to construction worker and vendor trips, fuel consumption for operation was estimated by converting the total CO2 emissions from the Project to gallons using the conversion factors for CO2 to gallons of gasoline or diesel. Based on the Traffic Impact Analysis prepared for the Project (Appendix F), the Project would generate 1,182 daily trips: 801 trips would be passenger vehicles, light-duty trucks, and motorcycles (68%), and 381 trips would be heavy- duty trucks and medium-heavy-duty trucks (32%) (Appendix F).
