There have been various environmental regulations established according to United Nations Framework Convention on Climate Change (UNFCC), and the industry of construction is no exception to those regulations. Although the industry of construction in Korea has been blamed as the biggest cause of global warming and environment pollution for emitting carbon dioxide (CO₂), it is now seeing the severity of the problem and is about to change. Those new environmental regulations are, however, not mandatory, but just recommendations, and criteria for CO₂ reduction are still insufficient, compared to their importance. The purpose of this study is to understand the relationship between the reduction of CO₂ emission and the score of Energy Performance Index (EPI), which is regulations on energy performance, so that it can be possible to check how much CO₂ is reduced as the score of EPI increases, and then to derive a regression equation. The objectivity of this study is to analyze the relationship between the amount of CO₂ reduction and EPI, which is stipulated in Standards for energy conservation being enforced in Korea, and then to draw a regression equation. For that objectivity, the amounts of CO₂ emission and reduction were checked as the scores of EPI items increase, with Visual DOE which is a building energy interpretation program, and those items affecting CO₂ reduction were gathered separately and regression equations for them were derived.
