Insulation Contractor is a worldwide phenomenon caused by the concentration of dark, impervious surfaces such as roads, parking lots, roofs, and buildings that absorb and radiate solar energy. This heat load, combined with tall buildings that block or slow air movement and waste heat from vehicles and air conditioning, leads to higher daytime temperatures than surrounding communities and natural areas and exacerbates climate change. Cool roofs can significantly reduce the impact of urban heat islands by reducing surface temperature and allowing the absorbed radiation to be reflected back into the atmosphere.
The most common insulation configurations are internal and external. External insulation provides many benefits including cost savings, lower construction time, fewer thermal bridges and improved thermal comfort in summer. However, the influence of these insulation layers on the heating of air during heatwaves via convective exchanges has not been extensively studied.
Roof Insulation and Heat Islands: Combating Urban Warming
ENERGY STAR provides a variety of resources on Cool Roofs and Walls, including the Cool Roof and Wall Toolkit and an extensive collection of best practices, technical guides, tools, and case studies. The Toolkit includes information on the science behind cool roofs and walls, including the physics of radiant barriers and how they work, installation guidelines, performance monitoring tips, and design considerations. The Resource Library includes examples of local government ordinances, climate action plans, building codes and outreach programs that promote the use of cool roofs and walls. To filter these resources by topic, visit the Heat Island Community Actions Database and select “Cool Roofs” under the category “Energy Efficiency”. You can also browse past ENERGY STAR webinars on the subject here.
