Building Insulation Law

The government recently passed a new law to make all buildings more energy efficient by 2020. The thermal insulation regulation standard of Japan has been criticized as inferior to that of other developed countries. For example, it is often pointed out that the regulation standard for insulating windows is inadequate. The new law is intended to bring Japanese thermal insulation building standards in line with global standards. It will be implemented by a variety of regulatory agencies, including the Ministry of Land, Infrastructure and Transport, Ministry of Economy, Trade and industry, and the Ministry of Environment.
