4.4 – Energy Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.4-13 Natural Gas Construction Energy Usage Natural gas is not anticipated to be required during construction of the Project. Fuels used for construction would primarily consist of diesel and gasoline, which are discussed below under the “petroleum” subsection. Any minor amounts of natural gas that may be consumed as a result of Project construction would be substantially less than that required for Project operation and would have a negligible contribution to the Project’s overall energy consumption . Operational Energy Usage Default natural gas usage rates in CalEEMod for the proposed land use and climate zone were used and adjusted based on compliance with 2019 Title 24 standards. According to these estimations, the Project would consume approximately 4,509,793 kBTU per year (Appendix B). This amount of natural gas is equivalent to 45,098 therms. For disclosure, in 2019, PG&E delivered approximately 4.9 billion therms to the region (CEC 2020b, 2020c). The Project would implement PDF-AQ/GHG-1, and buildings would be designed to achieve LEED certification and would include energy-efficient heating and cooling equipment, which would minimize the Project’s natural gas use. In summary, although natural gas usage would increase due to implementation of the Project, the Project would comply with the applicable energy standards and regulations, and usage would be decreased through green building standards. For these reasons, the natural gas consumption of the Project would not be considered inefficient or wasteful, and impacts would be less than significant. Petroleum Construction Energy Usage Heavy-duty construction equipment of various types would be used during each phase of Project construction. The CalEEMod analysis discussed in Section 4.1, Air Quality, and included in Appendix B lists the assumed equipment usage for each phase of construction. Based on that analysis, over all phases of construction, diesel-fueled construction equipment would run for an estimated 14,388 hours, as summarized in Table 4.4-1. Table 4.4-1.
