Urban areas, where these structures are highly concentrated and greenery is limited, become “islands” of higher temperatures relative to outlying areas. 0000009124 00000 n 0000035739 00000 n Cities 2017, 62, 131–145. 0000019888 00000 n 0000072602 00000 n Urban Land > Sustainability > Four Approaches to Reducing the Urban Heat Island Effect.

0000029332 00000 n Cooling Singapore identified potential strategies and measures for reducing the Urban Heat Island (UHI) and improving the Outdoor Thermal Comfort (OTC) in Singapore. These pockets of heat are referred to as “heat islands.” Heat islands can form under a variety of conditions, including during the day or night, in small or large cities, in suburban areas, in northern or southern climates, and in any season.A review of research studies and data found that in the United States, the heat island effect results in daytime temperatures in urban areas about 1–7°F higher than temperatures in outlying areas and nighttime temperatures about 2–5°F higher. 0000016250 00000 n 0000017459 00000 n Kong. Next, four cooling strategies were explored. An official website of the United States government.Many communities are taking action to reduce urban heat islands using five main strategies:  1) increasing tree and vegetative cover, 2) installing green roofs, 3) installing cool—mainly reflective—roofs, 4) using cool pavements (either reflective or permeable), and 5) utilizing smart growth practices. 0000033089 00000 n 0000010568 00000 n 0000001276 00000 n Time scale: Periodically (last updated August 2016) Background: 0000072920 00000 n The links below lead to detailed information on each of these strategies and examples of the activities that governments and communities are implementing. 0000036305 00000 n 0000035930 00000 n The urban heat island has a major effect on the cooling energy use in the summer.

It is being launched with the publication of a primer and implementation guide, which are designed to be helpful to cool surface novices and experienced cool program managers alike.The U.S. DOE's Guide to understanding and selecting the cool roof that is right for your home or building. Increase shade around your home Planting trees and other vegetation lowers surface and air temperatures by providing shade and cooling through evapotranspiration.
