Cool Pavements Brochure
Gilbert General Plan - The "Environmental Planning Element" in the Gilbert, Arizona general plan lists mitigating heat islands as a core goal. Specific policies under the goal include: 1) developing criteria to evaluate development projects that contribute to the heat island effect and identify mitigation techniques; 2) seeking partnerships with other municipalities, educational institutions, utility companies, government entities, and other to promote heat island awareness among landowners, developers, engineers, and architects; 3) encouraging design concepts utilizing planned and engineered green space and urban forestry to maximize shading of paved areas and buildings; 4) promoting education and awareness of the public, designers and applicants for the development and use of materials and construction techniques to help mitigate the urban heat island effect; and 5) providing for a reduction of the stormwater retention requirements where a grading and drainage report demonstrates a reduced stormwater storage capacity results from the use of pervious pavements on a site. One step in implementing the plan involved the development of a brochure on the use of cool pavements to reduce the urban heat island effect.Active

Arizona - TucsonDemonstration ProjectCool Retrofit - Thomas O. Price Service CenterCity of Tucson's Administration Building - A demonstration project for the City of Tucson documented how a cool roof reduced temperatures inside and on the roof of the building and saved more than 400 million Btu annually in energy. A white elastomeric coating was installed over a 28,000-square foot (2,600 m2), unshaded metal roof on one of the city's administration buildings. Following the installation, energy savings were calculated at 50 to 65% of the building's cooling energy – an avoided energy cost of nearly $4,000 annually. In addition to measuring the effects of adding a cool roof, the project will also investigate cooler paving materials and more trees and vegetation in the parking lots surrounding the building.Completed
California - BerkeleyClimate Action PlanCity of Berkeley Climate Action Plan (PDF)Cool Roofs - As part of the city's Climate Action Plan, Berkeley will consider requiring the installation of a cool roof anytime a commercial building is built or re-roofed. Cool roofs can achieve a solar reflectance of 70-80%, compared to 10-20% for a typical roof.Active
California - Chula VistaBuilding Standard / Energy Code; Green Building Program and Standards; Tree and Landscape Ordinance; Demonstration ProjectClimate 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.

California - StatewideBuilding CodeTitle 24, Part 6


2008 Updates
California Code of Regulations: California's Energy Efficiency Standards for Residential and Nonresidential Buildings - In response to electrical power shortages, the state of California added cool roofs as an energy efficiency option to its building energy code (Title 24) in 2001. The code defines a cool roof as having a minimum solar reflectance of 70% and minimum thermal emittance of 75%, unless it is concrete or clay tile, in which case it can have a minimum solar reflectance of 40%. This 40% rating incorporates new cool-colored residential products into the standard. In 2005, these cool roof provisions became mandatory requirements for all new non-residential construction and re-roofing projects that involve more than 2,000 square feet (180 m2) or 50% replacement. The code allows owners to meet these requirements in a variety of ways. The simplest approach is to apply a cool roof that meets the minimum requirements. Another alternative is to use products that do not fully meet the cool roof criteria and then offset those reduced performance levels by implementing other measures, such as insulation and window improvements, that exceed minimum requirements. The third, and most flexible option, is to use whatever methods are deemed practicable as long as the code's specific performance goal is reached; in this scenario, the building owner creates a model of all the characteristics that affect the energy consumption of the building to determine the mix of measures that will meet the code criteria. The California Energy Commission provides computer software for this compliance option. California began the process of updating Title 24 in late 2005, with final revised standards due in 2008. As part of this update, California is investigating extending cool roof requirements to the steep-sloped market.Active

Florida - Cocoa BeachDemonstration ProjectProfile of Success (PDF)Our Savior's Elementary School - Our Savior's Elementary School in Cocoa Beach participated in a study conducted by the Florida Solar Energy Center. The school applied a simple white acrylic coating to its 12,000-square foot roof. As a result, the reflectivity of the roof increased from 23% to 68%. Despite being an energy-efficient building, adding the roof coating reduced annual energy consumption by approximately 13,000 kWh and average electricity power demand to decline by 10%. Additionally, peak electric power demand fell by 35%. The roof coating saved the school approximately $850 per year and increased student and employee comfort.Completed

Massachusetts - BostonBuilding Standard / Energy Code; Green Building Program and StandardsBoston 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
New York - New York CityBuilding Standard / Energy CodeNYC CoolRoofsNYC CoolRoofs - In 2008 New York City put into place a building code that requires most new buildings to have 75% of the roof area covered with a reflective, white coating, or to be ENERGY STARŪ rated as highly reflective. Starting from January 2012, existing buildings that replace or renovate 50 percent or more are also required to add reflective materials to their rooftop. In addition, NYC °Cool Roofs address roofs on buildings that were built before the mandated codes took effect. To date 3,000 volunteers have coated 2.6 million sq ft of rooftops throughout the city. This program helps save money, preserve roof structure and cooling equipment, reduce energy use, reduce carbon emissions, and combat the urban heat island effect. Active
