주거용건물의 적정환기 횟수에 관한 연구 ( Study on the optimum air change rate in Residences )

Presently our concern and effort to save energy used in building are thought as a matter of course. But there are some unexpected side effects impairing our health in air tight and heavy insulation in buildings. It is indoor air contamination caused by increasing of pollutant gas such as CO2 that is the most important side effect. The purpose of this study is to show the optimum range of air change rate for fresh air supply in our residences. The air change rate was calculated by analysing in-situ experimental data and the standard CO2 concentration for health in our country.
