공동주택에 적용 가능한 친환경 건축기술의 경제효율성 지표(EEI) 제안

Abstract

This study aims to propose the Economic Efficiency Index (EEI) for green building technologies of apartment buildings. For this purpose, the categorization of green technologies was classified into resource reduction technology, energy saving technology, and energy production technology. After investigation of green technologies which were applied to apartment buildings, BFS concrete technology was proposed in resource reduction technology and LED lamp, low-e window, dimming control technology were contained within energy saving technology and solar system, a geothermal system, the solar thermal system were proposed in energy production technology. The EEI is a concept implicating rate of environmental performance and economic performance. Also, the concept of EEI is establishing a judgment in the aspect of environmental and economical performance of technology was proposed in order to inform the quantitative performance of each technology. Through comparing EEI of technology, it was able to figure out which technology is more efficient. The technology which has EEI over 1 and under -1, could be measured to be high efficient technology in the aspect of environmental performance. As a result, for the major green building technologies, the integrated environmental load reduction performance assessment which is the comparison to EEI was conducted, and through the EEI, the database was constructed.
