Japan’s Ministry of Land, Infrastructure and Transport and its Ministry of Economy, Trade and Industry are preparing new energy conservation standards for buildings with the goal of reducing energy consumption and greenhouse gas emissions. According to the proposed standards, which would be phased in next year, energy conservation for commercial and industrial buildings would be measured in a way that would encourage the use of advanced energy-saving products and equipment. Under separate standards for residential buildings, houses that have solar panel systems would receive bonus credit in the performance rating scheme.
