NOVEL COOL ROOF SOLUTION

摘要

Metal-based materials are widely used in urban areas, especially for infrastructure such as roofing system. Exposed to atmospheric conditions, which include environmental pollutants and relative humidity, these materials gradually corrode. During rains, a portion of the corrosion products is retained on the surface, while the other is released into runoff and washed away. Another important point is that that statistics reveal that home owners in the United States spend an average of $2000 annually for their utility costs, of which nearly 20% is due to air conditioning and office buildings tend to spend about 23% of their total energy cost for cooling purposes. To reduce this, one of the long-term solutions suggested by the Commercial Energy Advisor, USA is to provide reflective coatings for roofs and exteriors that will help in temperature control.
