City of Santa Ana Addendum to the <br />MainPlace Mall Transformation Project Fashion Square Commercial Center Final EIR <br />DG - 74 Materials and technologies that minimize environmental impacts, reduce <br />energy and resource consumption, and promote long-lasting development are <br />encouraged. <br />DG - 75 Window technologies such as tinting or insulated daylighting panels, <br />should be utilized to decrease the energy costs associated with cooling buildings <br />during most of the year. <br />As described previously, the 1983 EIR included Mitigation Measure 5.9-2 to require that <br />buildings be oriented such that solar radiation reduces heating loads and does not <br />increase air conditioning loads. However, current law under Title 24 is now more <br />stringent, and supersedes this mitigation measure. Further, the Specific Plan Design <br />Guidelines fulfill the requirements of the measure. <br />The current Title 24 standards substantially exceed the air quality and energy <br />conversation levels that would occur with the measure in 1983. Therefore, impacts <br />related to energy conservation would be less than significant. Thus, no new or <br />substantially greater impacts would occur with implementation of the proposed Project <br />when compared to those identified in the 1983 EIR or 1996 Addendum. <br />Conclusion for Energy Conservation <br />Based on the foregoing, none of the conditions identified in CEQA Guidelines section <br />15162 that would trigger the need to prepare a subsequent or supplemental EIR or <br />other environmental document to evaluate Project impacts or mitigation measures exist <br />regarding energy conservation. There have not been 1) changes to the Project that <br />require major revisions of the previous adopted EIR due to the involvement of new <br />significant environmental effects or a substantial increase in the severity of previously <br />identified effects; 2) substantial changes with respect to the circumstances under which <br />the Project is undertaken that require major revisions of the previous adopted EIR due <br />to the involvement of new significant environmental effects or a substantial increase in <br />the severity of previously identified effects; or 3) the availability of new information of <br />substantial importance relating to significant effects or mitigation measures or <br />alternatives that were not known and could not have been known when the 1983 EIR <br />was adopted as completed. <br />Mitigation Measures <br />The mitigation measure from the 1983 EIR is listed below. Explanation is provided as to <br />the status and applicability of the measure. <br />MM 5.14-1 The orientation of building glazing areas, overhangs, and site landscaping <br />should be selected in order for solar radiation to reach indoor areas during <br />the winter months to reduce heating loads. The same principal should be <br />incorporated for the summer months, so that building glazing, overhangs <br />and landscaping will reduce the amount of solar radiation reaching the <br />156 <br />
