About plan such as long-term excellent housing construction

The Law Concerning the Promotion of Long-Term Excellent Houses (hereinafter referred to as the “Long-Term Excellent Housing Act”) has been revised and
Effective February 20, 2022 and October 1, 2022 will be enforced in two stages.

●Major changes associated with the amendment of the Long-Term Excellent Housing Act on October 1, 2022
　①Establishment of a certification system for existing houses that do not involve building activities
　　We will create a system that allows excellent existing homes to be certified (certified only by the maintenance conservation plan) without extension or renovation.
　②Strengthening energy-saving measures and revising the amount of wall volume
　　The energy-saving standard shall be the level equivalent to ZEH, and the insulation performance class 5 and primary energy consumption class 6 in the housing performance labeling system.
　　With the weight of wooden buildings by installing heat insulating materials and energy-saving equipment, structural safety standards such as the required amount of walls, will be established.
　③Rationalization of standards pertaining to apartment houses
　　It will be streamlined by reviewing standards such as scale standards and long-term use structures.

Please see the Ministry of Land, Infrastructure, Transport and Tourism website (outside site) for details on law revision.
