Ⅰ. Introduction
1. Study background and objectives
Recently, due to environmental pollution and climate change, attention to environment is more growing than ever. Especially, buildings form 40% of energy and resource consumption, 30-40% of carbon dioxide emission, 20-25% of waste discharge, 17% of water consumption, and 25% of wood consumption, so buildings are mainly responsible for

2) 연구의 목적
본 연구는 기존의 ZEB 개념을 벗어나 이미 존재 하고 있는 건물에 ZEB의 개념을 도입하여 그 타당성 여부를 알아본다. 기존 ZEB의 평균 에너
