GREEN BUILDING PROGRAMCost Benefit AnalysisIn examining the costs and benefits of Green Building, we notethat there are two types of cost associated with building andmaintaining a development. Upfront Lifetime
GREEN BUILDING PROGRAMCost Benefit AnalysisWhen examining the long-term costs and benefits of GreenBuilding, it is also important to look at these various aspects: Maintenance costs Utilities costs Environmental impacts Total economic impact
GREEN BUILDING PROGRAMWhy include a Green Building program in ourCounty Code at this time? Conserve energy and water Reduce carbon emissions and footprint Comply with AB 32 (2006) Incorporate Green Building program into the General Plan andZoning Ordinance Updates
GREEN BUILDING PROGRAMThe built environment has a profound impact on ournatural environment, economy, health, and productivity.In the United States alone, buildings account for:65% of electricity consumption,36% of energy use,30% of greenhouse gas emissions,30% of raw materials use,30% of waste output (136 million tons annually),and12% of potable water consumption.Source: www.usgbc.org/DisplayPage.aspx?CMSPageID 1718

GREEN BUILDING PROGRAMGREEN BUILDINGS STANDARDSPurpose:The goal of this ordinance is to minimizenegative environmental and human healthimpacts as caused by construction,maintenance and operation of buildings.By incorporating green measures intodevelopment practices, we can increasepublic health, save energy and water andmaintain longer lasting and safer buildings.

GREEN BUILDING PROGRAMLOW IMPACT DEVELOPMENTSTANDARDSPurpose:Low Impact Development (LID) is an approach to site designand development that manages stormwater and other urbanrunoff.LID goals: Treat stormwater and other urban runoff Promote groundwater recharge through on-site infiltration Maintain and enhance natural resources systems whilereducing infrastructure costs.
GREEN BUILDING PROGRAMLOW IMPACT DEVELOPMENTSTANDARDSRecommendations:1. Work with public agencies to identify the most effective LIDdevelopment standards for private development and publicroads.2. Amend the county code to broaden requirements forlandscaping parking lots to include a greater number oftrees and explore the feasibility of landscaping buildingrooftops.

GREEN BUILDING PROGRAMDROUGHT-TOLERANT ANDNATIVE LANDSCAPING STANDARDSPurpose:The Drought-tolerant and Native Landscaping ordinanceestablishes guidelines for plant material, plantingtechniques and maintenance of landscaped areas forthe purpose of conserving water.
GREEN BUILDING PROGRAMDROUGHT-TOLERANT ANDNATIVE LANDSCAPING STANDARDSRecommendations: Require that a minimum percentage of plants be climaticallyappropriate for the area. Limit the percentage of turf permitted in a landscaped area. Require plant positioning that allows for efficient watering. Position trees so that they shade sidewalk, patios and driveways. Require the installation of both indoor and outdoor water meters tomonitor use in large developments.
GREEN BUILDING PROGRAMDROUGHT-TOLERANT ANDNATIVE LANDSCAPING STANDARDSType of Standards:A. County-approved plant list by geographic zones Percentage required of total landscaped area Native species vs. climatically appropriatespeciesB.
