A review is required for energy-saving measures in residential construction. While the administration is aiming to realize a carbon-neutral society by 2050, Taro Kono, Minister of State for Special Missions, decided in December last year to establish a "Comprehensive Inspection Task Force on Regulations on Renewable Energy, etc." Residential construction has become a focus as well as grid power and wind power. Although it is a field that spans multiple ministries, such as the formulation of energy-saving standards and the ZEH subsidy policy, the need for discussions to improve the compliance rate was pointed out, especially with the mandatory compliance of standards. The basic plan for living and living, which is currently being reviewed by the Ministry of Land, Infrastructure, Transport and Tourism, was also affected, and it was decided to state the intention to work on tightening regulations.
