　　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.
