Mrs. Rondash stated that only "must haves" are considered for total points; however, there are also 66 electives from which to choose in the residential categories, and 99 electives in the commercial category. She then described a scenario to meet current standards for the single - family residential and repeated the scenario for multi - family residences. Mrs. Rondash stated that staff's recommended action is consistent with Pleasanton's existing requirements, with a few minor changes to meet the State's new mandatory minimum requirements. She added that staff believes the developer cost to implement the CALGreen Tier 1 is equivalent to the cost to implement the City's existing green building ordinance, and that taking the action is likely to help developers save time and money while working on construction drawings. Ms Rondash then presented a cost analysis based on standard construction versus the Tier 1 measures in effect. She stated that Tier 1 would be equivalent to the City's current standards and would have a no cost impact. She added that the cost analysis does not include savings from reduced energy, water, medical bills, or existing incentive programs such as tax credits or rebates which would also reduce the payback projection from the approxirnately 10 -15 years. Mrs. Rondash also described the cost effectiveness study and payback projection prepared for the City's climate zone, which states incremental improvements in overall annual energy performance of buildings exceeded Title 24 by 15 percent. She added that the study further notes that the building's overall design, occupancy type, and specific design choices may allow for a larger range of incremental first cost and payback projections. She noted that the study did not consider the tax credit or rebates. Mrs. Rondash presented what other jurisdictions have in place, as follows: • City of Livermore o Has a green building ordinance; will amend their green ordinance to default to the CALGreen. They are looking to enact something that is not less than their current ordinance. They are still analyzing the new code, but think that their recommendation will ultimately be similar to Pleasanton's. • City of San Jose o Going with CALGreen basic for now. After next year they will be looking at offering an option for developers to go with a tier as an alternative to using the third party system. • City of Dublin o Has a green building ordinance; is recommending CALGreen basic with a local amendment to require PV prep on all new construction. They will keep their existing ordinance for all other projects. • City of Walnut Creek o No existing green building ordinance; will be adopting CALGreen basic.
