Wang Shichuan the first time the United States in 1975 enacted the ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineering Association) 90 ~ 75 new energy efficiency standards for building closed cell polyethylene foam design. On this basis, closed cell polyethylene foam in December 1977 officially promulgated closed cell polyethylene foam the "structure of the new building energy regulations," and in 45 states closed cell polyethylene foam received very significant energy closed cell polyethylene foam savings. The National Energy Board, the Bureau of Standards and the National Assembly building codes and standards, and continuously in the construction of new energy-saving design and other aspects of the content, every five years and will be a revision on the ASHRAE Standard. Foam glass developed emphasis on energy efficiency in buildings and take some effective measures, and achieved great success, building energy consumption in these countries dropped significantly. Such as Denmark in 1985 than in 1972 heating area increased by 30%, but the heating energy consumption has decreased by 3.18 million tons of standard coal, heating energy consumption closed cell polyethylene foam of the country's total energy consumption closed cell polyethylene foam rose from 39% down to 28%; U.S. since the formulation and perform energy efficiency standards to save a lot of money has been spent, estimated that in 2011, on this basis, but also save $ 43 billion. Thus, building energy regulations closed cell polyethylene foam abroad for over 30 years has achieved remarkable social and economic benefits. Building energy closed cell polyethylene foam efficiency is not only relying on building energy closed cell polyethylene foam regulations closed cell polyethylene foam promulgated executed, it also involves the implementation of a large industrial groups, including thermal insulation materials and products that affect building energy efficiency is an important factor. closed cell polyethylene foam
