本件は,内装材に天然木質系材料を中心に使用した場合の,揮発性有機化合物の低減効果を目的とした.具体的には,床と腰壁に下地を含めて天然木材を使用し,壁と天井に極力材料からの放散が少ない材料を選定した.また,施工段階別に濃度を確認することで,対策効果の確認も行った. 本研究は,一般的に使用される内装材料を用いて施工した場合の揮発性有機化合物の低減を目的とした.具体的には,床・壁・天井各部位の内装材料について,材料からの放散量を測定する.その結果から,材料の仕様を予め評価し放散量が少ないものを選定した.
また,施工段階別に室内濃度を確認し,対策の効果を確認した.

Indoor air quality in school facilities

This paper studies the reduction of VOC in a building where natural wood was used as the interior material for flooring, walls and ceiling.
Other than natural wood other material with low amounts of VOC emission were selected as far as possible. The effect of these measures was confirmed by measuring the VOC concentration during the construction stage, and 1 month after completion of construction, when the building with furniture was in actual use. The reduction of VOC when using general interior finishing materials was studied. The emissions from the materials used for flooring, walls and ceiling were determined, and from the results, the specification for the material was laid down. The indoor air quality was confirmed at each stage of work.
