Energy conservation for rental and custom houses 一 Present the proposal of conformity criteria and achievement time target.
On July 2nd, a joint meeting was held on July 2nd by the Ministry of Economy, Trade and Industry (METI) and Ministry of Land, Infrastructure, Transport and Tourism(MLIT) to examine specific energy conservation standards of the revised Building Energy Efficiency Act.
In response to the addition of custom-built detached houses and rental apartments to the system, the meeting proposed conformity criteria and achievement time target. Set the conformity ratio at 20-50% based on business types for the business operators that supply 300 custom-built detached houses per year and more than 1,000 units rental apartments and target year is assumed to be FY2024.
The government has promoted the establishment of a top runner system for the dissemination of energy-saving houses. For major housing companies that supply more than 150 single-family homes per year, recommendations had been made if their compliance is insufficient. The target of this system expands by this revision. According to the MLIT, approx. 70 custom-built detached houses and more than a dozen rental apartments are expected to be newly added.
In the background of the revised Building Energy Efficiency Act, there is an achievement of the Paris Agreement Target for the global warming countermeasures. The government has set a 26% reduction from FY2013 as a greenhouse gas emission reduction target for FY2030. While energy consumption decreased in the industrial and transportation sectors, it increased significantly in the commercial and residential sectors. Since the total share of commercial and residential sectors accounts for about 30%, further energy conservation measures for the buildings have been promoted. In addition, evaluation method for the heat and power supplied from other buildings were mentioned at this joint meeting. Discussion will be furthered and be coordinated by the end of October
