친환경 건축물의 가치 및 향후 과제 : 원가법을 중심으로

As environmental pollution and climate change intensify, many buildings are increasingly adopting equipment and materials that affect their energy efficiency. However, there are insufficient tools, guidance materials, and studies for determining the value of green buildings. When comparing the cost of green buildings and eco-friendly certification systems, we must consider whether the certification system is viewed from a regulatory or a benefit perspective. This study is a foundational study for the appraisal of eco-friendly buildings. It focused on building energy efficiency certification among eco-friendly certification systems and the construction cost factors that affect the cost method from a regulatory standpoint. Accordingly, we conducted a theoretical review focusing on research data pertaining to the domestic and international construction costs of eco-friendly buildings, as well as appraisal standards and guidelines. Additionally, examples of construction costs were applied and compared to reflect the value of eco-friendly buildings from the perspective of cost method. It is necessary to differentiate between use value and capital premium when calculating reconstruction costs and facility prices. In addition, an expert council must discuss cases in which the certification validity period has expired.
