Arizona - TucsonCool Roofs; Trees and Vegetation; Cool PavementsCool 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 - 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 - MercedCool PavementsSJVAPCD's Healthy Air Living (PDF)Light Pavement - UC Merced has implemented a new parking lot that uses light pavement. Gravel aggregate is used for car parking spaces, which reduces heat absorption because it is a more reflective surface. Additionally, it is more permeable than asphalt, which reduces stormwater runoff.Completed
California - SacramentoCool PavementsPervious Concrete PavementsPermeable Parking Lot Demonstration - The Sacramento Cool Communities Program was a partner in a project to install a pervious concrete parking lot at Bannister Park in Fair Oaks in 2001 to enhance stormwater management and to reduce the urban heat-island effect. This parking lot is one of the first in the state to use this type of paving. Pervious concrete helps water infiltrate the soil by capturing rainwater in a network of voids and allowing it to percolate into the underlying soil. Pervious concrete can help reduce or eliminate the need for traditional stormwater management systems such as retention ponds and sewer tie-ins.Completed
California - StatewideGreen Roofs; Trees and VegetationCalifornia Urban and Community ForestryCalifornia Urban Forestry Program - This program is the lead for the development of sustainable urban and community forests in California. It provides information, education, and assistance to local governments, non-profits, private companies, and the general public that help to advance urban forestry initiatives. Through the program, the state plants an average of 10,000 to 20,000 trees a year. Local governments and non-profits can apply for grants from the program; eligible projects include non-traditional urban forestry initiatives such as green roofs. In Fiscal Year 2009/2010, the program funded a green roof project in San Diego.Active
District of Columbia - WashingtonGreen RoofsCourt 5 Green RoofUSDA South Building Court 5 Green Roof - This 3,500 square foot green roof followed the installation of a 500 gallon cistern that catches runoff from an adjacent roof and provides irrigation for the new green roof. The green roof reduces the urban heat island effect, is more aesthetically pleasing than conventional roofs, and manages stormwater runoff that is entering local waterways and the Chesapeake Bay.Completed
Florida - Cocoa BeachCool RoofsProfile 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

Georgia - AtlantaGreen RoofsFrances Bunzl Administration Center Green RoofFrances Bunzl Administration Center Green Roof - The green roof on top of the High Museum of Art’s Frances Bunzl Administration Center was completed in April, 2008. It will help to mitigate the urban heat island effect, reduce energy consumption, and improve air quality in downtown Atlanta. The roof was financed partially through a Nonpoint Source Implementation Grant from U.S. EPA, which is awarded to projects that address non-point source pollution through strategies such as stormwater management. This modular green roof will be able to retain about 70% of total rainfall, or 62,000 gallons of stormwater per year. The project also allowed the Savannah College of Art and Design to take part in the plant selection and to film a documentary on the module installation.Completed
Illinois - ChicagoCool PavementsPermeable AlleysCool Paving Demonstration Alley - In the fall of 2001, the Chicago Department of Environment reconstructed an asphalt alley using a permeable system. Using a porous gravel structure the city was able to eliminate formerly chronic flooding without using the sewer system, while reducing the heat island effect by eliminating dark, heat absorbing surfaces. This paving can absorb 3 inches of rainfall per hour, allowing rainwater to soak into the ground and reducing polluted runoff and flooding.Completed

Illinois - ChicagoGreen Roofs; Trees and Vegetation; Cool PavementsGreen Alleys

Green Alleys Handbook (PDF)
Chicago Green Alleys - Chicago, after the success of a demonstration project using permeable pavement, began a Green Alley initiative to use permeable pavement any time it needs to re-pave an alley. Through 2009, more than 100 Green Alleys have been installed and ultimately, almost 2,000 miles of alleyways will be made permeable. The Green Alley Handbook notes that "if all the alleys had a light, reflective surface (high albedo) that reflected heat energy, [they would stay] cool on hot days and thereby reducing the "urban heat island effect." The handbook also mentions the heat island reduction benefits of shade trees and green roofs.Active
Illinois - ChicagoGreen RoofsCity Hall Rooftop GardenChicago's City Hall - The City of Chicago installed a green roof on its city hall that includes 20,000 plants, shrubs, grasses, vines, and trees. This 20,300 square foot roof is about 100 degrees cooler than nearby roofs. The city has saved about $5,000 in energy costs annually, and savings may increase as energy prices fluctuate. In addition to assessing energy impacts, the green roof has been designed to test different types of rooftop garden systems, success rates of native and non-native vegetation, and reductions in stormwater runoff. This city hall green roof has helped to raise the visibility and increase public understanding of green roofs. Chicago's Department of Environment staff has frequently given presentations about the roof, which has won numerous awards.Completed

Michigan - DetroitCool Pavements Detroit Metro Airport Terminal Expansion Slag Cement Detroit Airport Expansion - The Detroit Metro Airport used 720,000 square feet (67,000 m2) of slag cement in an airport terminal expansion project. In this region, the local aggregate is susceptible to alkali-silica reaction, whereas slag resists that form of corrosion better than plain cement and is easier to place in hot weather. This approach increased the life expectancy of the paved surfaces, as well as allowed for the use of a high-albedo product.Completed
