California - Chula VistaCool Roofs; Trees and Vegetation; Cool PavementsClimate Change Working Group – Climate Action PlanningBuilding Code; Demonstration Project; Green Building Program and Standards; Tree and Landscape Ordinance - The City of Chula Vista has identified 11 climate adaptation strategies, three of which directly address urban heat islands: they include the installation of cooler paving products, cooler roofing materials, and the incorporation of more shade trees. The city is sponsoring a demonstration project that will evaluate multiple reflective pavement technologies and develop implementation options based on these results. It is also working to amend its green building standards code to require cool roofs on all new residential developments, as well as developing a policy to require all municipal improvement projects and private parking lot development projects to incorporate a certain percentage of shade trees based on the development size.Active
California - MartinezCool Roofs; Trees and VegetationThe City of Martinez Climate Action PlanMartinez Climate Action Plan - Martinez Climate Action Plan – The City of Martinez is addressing the issue of urban heat islands in its climate action plan. The city aims to reduce the heat island effect through targeted upgrades of existing buildings and paved areas; adoption of new building standards, including the new cool roof standard contained in California’s Title 24 Energy Standards; tree planting; and new requirements for shading in new parking lots and other large paved areas.Active
California - San JoseTrees and VegetationGreen Building PolicySan Jose Green Building Policy - The City of San Jose, California, includes landscape design for heat island mitigation as one of the goals of its Green Building Policy, adopted in 2001. The policy applies to planning, design, construction, management, renovation, operations, and demolition of facilities that are larger than 10,000 square feet and constructed, owned, managed, or financed by the city.Active
California - StatewideCool PavementsAB 296 Bill AnalysisAB 296 (Skinner) - AB 296 requires that the California Department of Transportation (Caltrans) develop and publish a Cool Pavements Handbook that would outline a standard specification for cool pavements. Caltrans would also be required to conduct one or more cool pavement pilot projects and to report the cost information and results of the pilot projects to the California Legislature, and to incorporate references to the handbook in its Construction Manual. Caltrans would be encouraged to work with other state agencies in California, and authorized to enter into an agreement with federal agencies such as EPA, or the Department of Energy, for development of the handbook. The Building Standards Commission would be required, for the next triennial code adopted after January 1, 2015, to consider incorporating the specifications from the Cool Pavements Handbook into the California Green Building Standards Code.Active
California - StatewideCool Roofs; Green Roofs; Trees and Vegetation; Cool PavementsCALGreen (PDF)California Green Building Standards Code - The 2010 California Green Building Standards Code, referred to as CALGreen, went into effect on January 1, 2011. The Code covers residential and commercial buildings, and provides 52 nonresidential mandatory measures and an additional 130 provisions for optional use. There are several voluntary measures that relate to heat island mitigation, including shading, cool pavement, and cool roof technologies.Active
California - WindsorCool RoofsGreen Building OrdinanceGreen Building Ordinance - The Green Building Ordinance in Windsor, CA applies to all new residential and commercial construction projects as well as remodels that consist of at least 75% reconstruction of total building/residency. The ordinance states that buildings must follow “green building standards,” which include the use of certified sustainable wood products and energy-efficient construction designs, as well as the incorporation of shade trees and cool reflective or green roofs.Active
Maryland - AnnapolisTrees and VegetationSee Chapter 17.14Annapolis Energy Efficiency Resolution - In October 2006, Annapolis, Maryland adopted a comprehensive energy efficiency resolution that included general goals and specific long-term targets for adopting a range of energy efficiency measures. One recommendation was to increase tree shading so that the city could sequester carbon dioxide, reduce the urban heat island effect, and lower ozone levels. In 2007, the city adopted a new tree protection ordinance as one step to protecting existing shade trees. This resolution also proposed green building goals, including adopting green building standards for public buildings, investigating incentives for green building construction, and developing an outreach and education program for the building community and government staff. The resolution also proposes increasing the urban forest canopy to 50% of the city’s land area by 2036.Active
Massachusetts - BostonCool Roofs; Green Roofs; Trees and Vegetation; Cool PavementsBoston Implements Green Building Zoning CodeGreen Building Zoning Code - Boston is decreasing carbon emissions associated with energy use in privately owned and operated buildings by implementing a Green Building Zoning Code. The zoning code requires all major construction projects greater than 50,000 square feet to adhere to the U.S. Green Building Council’s LEED certification standards. Two of the points for this certification can be obtained by using urban heat island reduction strategies, one point coming from cool or green roofs and the other from non-roof strategies.Active

The Pedernales Lofts Case Study
The Pedernales Lofts - The Pedernales Lofts is the first multi-family development in Austin to receive five stars on the Green Building Multi-Family Rating. The rating system allows for one point if a heat island reduction strategy is used. The Pedernales Lofts used reflective roofing and pervious pavements, and was built on a former industrial brownfield. It also received S.M.A.R.T. Housing fee waivers – S.M.A.R.T. Housing rules ensure homes are Safe, Mixed-income, Accessible, Reasonably priced, and Transit-oriented. Only one star on the Green Building Multi-Family Rating system is needed to receive the S.M.A.R.T. housing fee waiver.Completed

Austin Climate Protection Plan
Austin Heat Island Mitigation - In May 2001, the Austin City Council adopted a heat island mitigation resolution that committed the city manager to review recommendations for a variety of activities to diminish the city's heat island. In September of that year, the City Council awarded $1 million towards implementing the recommendations, which ranged from developing a cool roof strategy to increasing enforcement of the city's tree-saving ordinance. Austin's Climate Protection Plan incorporates heat island reduction through its green building and energy efficiency elements.Active

Urban Heat Island Project
Dallas Sustainable Skylines Initiative - The Sustainable Skylines initiative is a three-year partnership between the City of Dallas, the U.S. Environmental Protection Agency, and the North Central Texas Council of Governments (NCTOG) to promote sustainability within the City via voluntary programs which emphasize air quality improvements. The initiative has identified the following categories of potential projects to initially perform together: green buildings project, creating a greenhouse gas strategy, green taxis project, off-road equipment replacements and retrofits, renewable energy/energy efficiency outreach program, and an urban heat island project. The goal of the urban heat island project is to develop and implement an urban heat island program for the City of Dallas that will both decrease heated surfaces and increase permeability of surfaces in the Central City and other areas of Dallas.Active
Texas - DallasCool RoofsSee Item #3 (PDF)Dallas Green Building Program Ordinance - The City of Dallas passed this ordinance to establish a green building program. The program will consist of two phases; the first phase focusing on energy efficiency, water conservation and reduction of the heat island effect through cool roofs, and phase two will expand phase one to implement a comprehensive green building standard for all new construction. For new proposed commercial projects affecting less than 50,000 square feet of floor area, the requirements include energy efficiency, water conservation, cool roof requirements for low-slope roofs, and an outdoor lighting restriction.Active
