  • Heat Island Reduction Roof, Information on how to use cool, reflective roofs to reduce the heat island effect ARTICLE BY GEORGIANN POTTSPHOTOGRAPHY BY KELLY MOORE CLARK When Bishop Delores J. Oct 23, 2025 · This paper reviews existing literature on rooftop mitigation of UHI, summarizes specific existing rooftop mitigation measures, and examines the comparative effectiveness of various rooftop mitigation strategies in reducing urban heat islands. \u003C/p\u003E\u003Cp\u003EWhat can cities do to reduce their temperatures? The construction of green roofs for the heat island areas within the fifth ring road of Beijing can reduce the area of high-temperature and sub-high-temperature zones by 52. Learn about the types of roofing materials to consider for your next roofing project. communities. A cool roof strategy is a one that seeks to use heat absorbing and/or dissipating roofing materials and technologies. India is urbanising at a rapid pace. Rising temperatures continue to threaten the health of all New Yorkers, but particularly older adults, those without access to air conditioning, and those with a variety of health conditions. The tabs below outline each rating system's requirements and options for seeking the heat island reduction credit. These heat islands form because urban surfaces such as roadways and rooftops absorb and emit heat to a greater extent than most natural surfaces. As cities bake up to 10°F hotter than surrounding areas, dark commercial roofs are acting like massive heat sponges, cranking up cooling costs and cooking our air quality. Health Impact Improvements for Urban Residents Through Urban Heat Island Mitigation: A Case Study on Increasing Roof Surface Reflectivity Article Full-text available Feb 2026 If you make home improvements for energy efficiency, you may qualify for an annual tax credit up to $3,200. As with trees and vegetation elsewhere, vegetation on a green roof shades surfaces and removes heat from the air through evapotranspiration. This roof works as a super insulator by reducing cooling expenses inside the building. Even so, she believed with all of her heart that He had a plan, and she waited and trusted. These two mechanisms reduce temperatures of the roof surface and the surrounding air. Nonroof The LEED intent is to minimize impact on microclimate and human and Green roofs are an emerging technol ogy that can help communities miti gate urban heat islands. These cool roofing techniques can lower air conditioning needs, reduce energy bills, and lessen the urban heat island effect, making them an environmentally friendly choice for both new and existing buildings. Applicable Credits: OPTION 1. Green roofs provide shade and remove heat from the air through evapotranspiration, reducing temperatures of the roof surface and the surrounding air. The surface of a Reflective surfaces and light finishes reduce heat absorption and help mitigate the urban heat island effect. 55% and 29. Reflective roof surfaces, known as cool roofs, cause a cooling effect by reflecting heat rather than absorbing it. Discover more about the urban island heat effect and how this type of roofing system can reduce the heat produced in urban environments. This reduces heating and cooling energy use, thus helping to reduce greenhouse gas (GHG) emissions. On a warm day, conventional roofing materials may reach as much as 66°F warmer than the surrounding air temperatures. The building can hold in more heat in winter and keep out the heat in summer. S. When paired with advanced coatings and modern sealants, these roofing materials improve insulation and enhance efficiency. ” The intent is to minimize effects on microclimates and human and wildlife habitats by reducing heat islands. Although cooling heat islands is an important aspect of urban climate change mitigation, an even bigger impact could come from large-scale energy conservation. Read the latest press releases, executive orders, statements, and transcripts from the NYC Mayor's Office. Cool roofs reduce urban heat island effect. iTree Exit —A U. An eco-friendly investment, cool roofs help with heat island mitigation. EPA's Heat Island Effect Site provides information on heat islands, their impacts, mitigation strategies, related research, a directory of heat island reduction initiatives in U. Infrared thermography was used to monitor surface temperatures at various points on each roof. Installing a new roof on a commercial building is a major investment that affects operating costs, energy efficiency, and long-term asset value. Use Cool Roofs and Reflective Materials 5. May 30, 2025 · A cool roof absorbs and transfers less heat from the sun to the building compared with a more conventional roof. Typically heat island mitiga tion is part of an energy, air quality, water, or sustainability By reflecting solar heat and reducing the heat island effect, cool roofs play a pivotal role in conserving energy, reducing environmental pollutants, and enhancing the health and comfort of communities.
