City of Santa Ana Addendum to the MainPlace Mall Transformation Proiect Fashion Square Commercial Center Final EIR 5.14 ENERGY CONSERVATION Summary of Impacts Identified in the 1983 EIR The 1983 EIR described that the expansion of the onsite development would increase energy consumption, but that proposed structures would have to be designed to meet the State's energy conservation standards and would be enforced through the building permit process. The 1983 EIR also included Mitigation Measure 5.14-1 to orient buildings and landscaping, such that solar radiation reduces heating loads and does not increase air conditioning loads. The EIR determined that impacts would be less than significant with implementation of the mitigation measure. Summary of Impacts Identified in the 1996 Addendum The 1996 Addendum described that the proposed development would be designed for optimum energy efficiency, in accordance with the State's Energy Conservation Standards, and that the addition would result in a limited and less than significant increase in energy consumption. Impacts Associated with the Proposed Project No New Impact. Consistent with the Originally Approved Plan, the proposed Project would generate demand for electricity, natural gas, as well as gasoline for motor vehicle trips. Operational use of energy includes the heating, cooling, and lighting of building areas, water heating, operation of electrical systems and appliances within residences, parking lot and outdoor lighting, and the transport of electricity, natural gas, and water to the areas where they would be consumed. This use of energy is typical for urban development, and no operational activities or land uses would occur that would result in extraordinary energy consumption. The proposed Project would be required to meet the current Title 24 energy efficiency standards, which are updated on 3-year cycles. The City's permitting process includes review of energy conservation measures to ensure that all requirements are met. Typical Title 24 measures include insulation; use of energy -efficient heating, ventilation and air conditioning equipment (HVAC); solar -reflective roofing materials; energy - efficient indoor and outdoor lighting systems; reclamation of heat rejection from refrigeration equipment to generate hot water; and incorporation of skylights, etc. Additionally, the proposed Project includes features to reduce energy consumptions, such as 25 electric vehicle charging stations and the following Specific Plan Design Guidelines: DG - 10 Buildings should be oriented to take advantage of sun angles and exposure in order to minimize the need to mechanically heat or cool the building at different times throughout the year. 155
