Abstract

In Japan the Great East Japan Earthquake had occurred on March 11th in 2011. There were serious damages in seaside cities of the Pacific Ocean in Tohoku district. Many people in these areas had lost their houses and more fifty thousand temporary houses were built in three prefectures of the Tohoku district. Most temporary housing units are terrace houses, and distance between buildings is narrow, and the performances of the indoor environments are not enough to keep adequate indoor qualities. Therefore, we are anxious about the possibility several problems may occur, such as indoor thermal environment and indoor air quality as well as sound environment problems. This research aimed to investigate the indoor air quality, especially VOC concentrations in indoor air and SVOC (semi-volatile organic compound) in settled dust in the temporary residential housings. In the summer seasons in 2011, measurements have been conducted in 62 residences of the temporary housing and measuring results were compared with guideline value in Japan. As a result, TVOC concentrations in the most houses were over tentative guideline value in Japan, 400 μg/m 3.
