Heat Island Effect Portal
This website provides information on the heat island effect, its impacts, and the strategies that communities can take to reduce urban temperatures. Look under the "Where You Live" section to see specific strategies and initiatives implemented by states and localities. Strategies fall into four primary categories: cool roofs, cool pavement, green roofs, and urban landscaping. Initiatives are specific policy mechanisms, such as building codes, comprehensive plans, demonstration projects, incentives, landscape ordinances, state implementation plans, and zoning codes.
