Abstract

In this study, technical factors necessary for achieving certification and improving quality were summarized for small-sized office that obtained the first rating of Zero Energy Building(ZEB) certification. In addition, quantitative analysis such as ECO-2 energy simulation, economic analysis of Net Present Value(NPV), and Life Cycle Assessment(LCA) was performed. The NPV is KRW -2.2 billion, which is not economical. However, when environmental costs were applied through the LCA, the NPV was KRW -1.8 billion, which could offset about 20% compared to the previous one. In addition, through previous studies and literature review, the current status of institutional and financial benefits related to ZEB in Korea, and the relationship between ZEB and domestic G-SEED certification were analyzed, and additional improvement directions were proposed.
