レンジフードの設計仕様を見ればなんちゃって高性能住宅会社を見破れる

Houses that only meet the three major performance criteria—G2 rating, C-value of 1 or less, and seismic resistance rating 3—while neglecting other factors such as durability and cooling, are called "pseudo-high-performance houses." A simple way to identify these is by checking the design specifications of the range hood, which is why we're introducing it here. While simultaneous supply and exhaust range hoods have been considered essential items in highly airtight houses, there has been an increase in cases of condensation occurring in these houses during the summer. We will explain the causes and countermeasures in detail.
