The Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism held a joint meeting on September 2nd, presented the draft of the government ordinance including conformity standards of the Building Energy Efficiency Act. For the top-runner system that promotes energy conservation, the draft additionally covered the business operators that provides more than 300 custom-built detached houses per year and rental apartments that provide more than 1,000 units. for the system that relaxes the floor area ratio corresponding to the facilities when energy-saving equipment is introduced, new initiatives of cooperation between multiple buildings were also approved.
In the background of the review of the housing top runner program, there is a sense of crisis about reducing the greenhouse gas emissions. Compared between the FY2005 and FY2013 emissions, the industrial / transport sector has been reducing, but the commercial / residential sector, mainly housing and buildings has increased.
Responding to this, in the government’s target of a 26% reduction in 2030 compared to the FY2013 in all the sectors, the target has been deepened to approximately 40% for the commercial / residential sector.
Expand the housing top runner standard for business operators that provide more than 150 single-family homes per year and promote further energy conservation.
Regarding the floor area ratio exception by introduction of energy-saving equipment, introduction of the cogeneration equipment will encourage the efforts to save energy in multiple buildings. The floor area corresponding to the equipment is excluded from the floor area ratio calculation with an upper limit of 10% of the total floor area. Encourage the installation of energy-saving equipment while increasing the greater design flexibility of buildings.
