사무소 건물에서 냉난방 및 조명에너지 동시 절감을 위한 외피 설계 요소 분석

초록

This study aims to assess the impact of envelope design factors on the total energy consumption of cooling, heating, and lighting sector inoffice buildings and to suggest priorities among energy-saving design alternatives. The approach involved selecting a baseline model andvarious variable levels for the office building, followed by energy analysis simulations using the design of the experiment method. Sensitivityanalysis, based on energy consumption data obtained from these simulations, calculated the contribution rate and influence of each designfactor. Additionally, a design-stage alternative flow chart was presented, and a predictive energy consumption equation was developed throughmultiple regression analysis for additional analysis. The study presents a method enabling designers to compare diverse alternatives based onenvelope design factors in the early design stage and choose the energy-efficient optimal design alternative.
