AN EASY EXAMINATION METHOD ON AIRTIGHTNESS OF DETACHED HOUSES FOR VICTIMS OF GREAT EAST JAPAN EARTHQUAKE

Single point method using a range fan and carbon dioxide of a combustion gas

Abstract

 The aim of this study is to use the building environmental performance as a base of healthy life of victims after great east japan earthquake in 2011. The equivalent leakage areas of the houses for victims were investigated and an easy measurement method was developed to the airtight levels to be high in the houses. The results showed the followings.
 1. The equivalent leakage area varied in the houses and are not enough for the latest building code for energy saving in some cases under the high housing demand for the victims.
 2. An easy examination method using a fan in kitchen is useful to check the airtight levels in houses which equivalent leakage area is less than about 2.0 cm²/m².
