City of Pleasanton—Hidden Canyon Residences and Preserve Draft EIR Energy FirstCarbon Solutions 3.5-9 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-05 Energy.docx construction year and calculated for the vehicle categories for each vehicle type in CalEEMod. For Workers, the assumed fleet is based on field observations and is 25 percent light-duty auto (LDA), 50 percent light-duty truck type 1 (LDT1), and 25 percent light-duty truck type 2 (LDT2). Haul trucks were assumed to be 100 percent diesel heavy heavy-duty truck (HHDT). Vendor trucks during building construction were assumed to be entirely diesel-fueled and 50 percent medium heavy-duty truck (MHDT) and HHDT, while asphalt vendor trucks were assumed to all be diesel-fueled HHDT. 3.5.6 - Operation Mobile Sources Fuel consumption factors for operational mobile sources were calculated based on the VMT and operational fleet for each land use modeled in CalEEMod. The Emission Factors mobile source emissions model (EMFAC ) WebTool was used to develop fuel consumption rates corresponding to the County fleet for the Operational Year modeled in CalEEMod. These up-to-date inventories include electric and conventional vehicle inventory data as well as Compressed Natural Gas (CNG) bus and truck data. Electric usage was characterized as kWh/vehicle-mile and fossil fuel usage by mpg. CNG usage is reported in gallons equivalent. Building Energy Natural gas and electricity estimates are based on CalEEMod energy calculations and included Title 24 and Non-Title 24 energy based on size, land use, electricity demand forecast zone and climate zone. CalEEMod energy calculations are based on 2019 Title 24 standards, providing somewhat conservative estimates of building energy use.15 The proposed project will be all-electric, and therefore is not associated with natural gas use. The additional electricity use to compensate for the lack of natural gas use has been accounted for in CalEEMod energy calculations. Most common natural gas end uses, which will be replaced by electricity, include space heating, water heating, and range (i.e., cooktop plus oven). Additional natural gas end uses include dryer, auxiliary heat, pool heat, spa heat, solar water heater with natural gas backup, and miscellaneous. The detailed energy calculation sheets are included as Appendix B. 3.5.7 - Thresholds of Significance The lead agency utilizes the criteria in the CEQA Guidelines Appendix G Environmental Checklist to establish thresholds of significance to determine whether impacts to energy are significant environmental effects. As such, the City has determined that the proposed project would have a potential impact if it would: a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation. b) Conflict with or obstruct a State or local plan for renewable energy or energy efficiency. 15 California Air Pollution Control Officers Association (CAPCOA). 2021.
