Proposed to be consistent with Ministry of Land, Infrastructure, Transport and Tourism = HEAT20, low carbon certification standard requires introduction of renewable energy

The Building Environment Subcommittee of the Building Subcommittee of the Social Infrastructure Development Council of the Ministry of Land, Infrastructure, Transport and Tourism holds a subcommittee and a working group on energy-saving performance standards, and sets the ZEH level in the certification standards for low-carbon buildings and the housing performance labeling system. We discussed the higher grades.

The Ministry of Land, Infrastructure, Transport and Tourism has proposed that the setting of grades exceeding the ZEH level in the housing performance display should be the same as G2 and G3 of HEAT20 in the case of detached houses. However, only 5 regions that will reduce significantly more than the target reduction rate will be at the same level as 6 regions.

In addition, the certification standard for low-carbon buildings is to match the ZEH standard (excluding the renewable energy part) for the energy-saving performance of houses, and the certification standard requires the introduction of renewable energy such as solar power generation.

In the upper grades of the housing performance display, grades 6 and 7 will be newly established according to G2 and G3 of HEAT20, and the reduction rate of primary energy consumption for heating and cooling will be used as a guide, and grade 6 will reduce by about 30%. , It was proposed that about 40% should be used as a guide for grade 7.

However, if the G2 and G3 levels are used in 5 regions, the reduction rate will be 39% in the grade 6 plan and 49% in the grade 7 plan. rice field.
