High albedo, or cool, roofs are moving from a niche sustainability feature to a mainstream building requirement. This growth is driven by stricter energy codes, corporate sustainability goals, and a global push for urban heat island mitigation.
Albedo Roofs is specifically designed to reduce internal building temperature by reflecting the suns UV rays.As one would expect, albedo roofs are formulated with special, high eminence materials that keep project a high level of thermal energy back into the atmosphere.
high-albedo roof effectiveness in single-family residential buildings. Based on our simulation results, we.roof albedo change under version 3 of the Typical Meteorological Year (TMY3) weather data. This gave. us the direct benefits of high-albedo roofs to different buildings.
Variety of Albedo Roofing Materials. Several materials can achieve high albedo properties, including: Reflective Roof Coatings: Applied as a liquid, these enhance the repelling properties of existing tops.
The result of using a vault roof with high albedo coating shows a fall of 53% in discomfort hours and saves 826 kW h during the summer sea-son compared to the base case of the conventional non insulated at roof in a typical Cairo residential buildings.
1. INTRODUCTION High-albedo roof coatings can be used to reduce building cooling loads. By lowering the absorption of solar energy, high-albedo coatings reduce building surface temperatures, and heat-transfer to the building interior.
