Promoting alternative transportation as a convenient and viable option through site selection, design, and incentives benefits both the building occupants and the developer. Recognizing the importance of alternative transportation in reducing negative environmental impacts, the LEED rating systems include multiple credits thal give project teams flexibility when considering site-specific needs and opportunities. Strategies to address transportation include t he followi ng, • locate near mass transit Select a project site in an area served by an existing transportation network. • limit parking. The lack of parking spaces on the project site will spark interest in alternati .... e transportation options. • Encourage carpooling. Designate preferred spaces for carpool .... ehicles in the par ki ng area. • Promote alternative-fuel vehicles. Provide a con .... enient refueling station on the site. • Offer incentives. Develop an alternati .... e commuting incent ive program for building occupants. • Support alternative transportation. Promote alternatives to single-occupancy car commuting at the building andlor city level. Primary Resources: Transportation, Energy, and Gree nhouse Gas Emiss ions Greenhouse gas emissions from transportation are the result of three fundamental factors : vehicle technology, transportation fuels, and land use. Although efforts are underway to improve vehicle fuel efficiency and reduce the carbon intensity of motor fuels, recent research suggests that these efforts may be insufficient to meet greenhouse gas reduction goals without significant changes in land use. Land use is what ultimately drives growth in transportation demand, and urban sprawl is increasing transportation dema nd faster than vehicles and fuels can improve. The result may be a net increase in greenhouse gas emissions despite substantial investments in technology and alternative energy. Green building professionals can help prevent this outcome by helping reduce transportation demand and slow or reverse the long-term growth in vehicle miles traveled . • Commuting guide for employers, www.self-oropeJled-city.com. • Growing Cooler: The Evidence on Urban Development and Climate Change, by Reid Ewing, Ke ith Bartholomew, Steve Winkelman, Jerry Walters, and Don Chen (Urban Land Institute, 2008) • Smart commuting, www.smartcomute,org.

THINK ABOUT IT Electric cars and net-zero buildings. Buildings create the demand for transportation. In t he future, they may also supply the energy to fuel our transportation system . What are the implications of the growing convergence between vehicles and buildings How will electrification of vehicles transform transportation and bui ldings How might it alter ene rgy efficiency or on site renewable energy goals for buildings SITE SELECTION The selection of a project site can provide opportunities to protect habitat and restore degraded areas . Development or rcdevelopmenton former industrial properties (so-called brownfields) may require the cleanup of contaminated sailor groundwater. Brownfield redevelopment can be regenerative: it improves the quality of the environment. This strategy also reduces pressure for the development ofgreenfie\d (undeveloped) Sites, which in turn reduces fragmentation of natural habitats. Some projects rake the extra step of explicitly protecting additional habitat outside the project boundaries as part of the development process. Strategies to address site selection include the following: • Increase density. Create a smaller footprint and maximize the floor·area ratio or square footage per acre. • Choose redevelopment. Build on a previously developed or brownfield site. • Protect habitat. Give preference to locations that do not include sensitive site elements and land types. lEED in Practice Smart locations and LEED for Neighborhood Development LEED for Neighborhood Development encourages development within and near existing communities or public transportation infrastructure. The goal is to reduce vehicle trips and miles traveled and support walking as a transportation choice. This promotes public health and a vibrant communitylife. One measure of "smart location" is access to transit service. LEED recognizes projects that locate at least 50% of dwelling unit entrances within a l/4 -mile walk of bus or streetcar stops or a 1/2 -mile walk from bus rapid transit, light or heavy passenger rail stations, ferry terminals, or tram terminals. 30 Green Bu ilding and LEED Co re Concepts Guide
