About this pageAI generated

This page summarizes the 2024 amendments to Japan's Building Energy Conservation Law, aimed at achieving carbon neutrality by 2050. Key changes include: imposing energy performance improvement efforts on building owners and explanation duties on architects; expanding energy efficiency compliance requirements to all new residential and non-residential buildings; requiring compliance for renovation work on modified portions; enhancing the Top Runner Program for housing; introducing an energy performance display system; and simplifying compliance judgment procedures. These measures promote energy consumption reduction in the building sector and increased wood utilization.
