| Abstract |
Recently, climate change caused by global warming and change of water consumption pattern following population growth bring world attention to the problem of water shortages. In South Korea which has already been classified as a water shortage country, saving water resources and securing usable water in residential buildings known for using a great quantity of water are directly linked with tackling the nationwide water shortage issue. Therefore, it is essential for residents to change their perception of the problem and voluntarily participate in saving water resources. Accordingly, in this research I examined how the saving factors for water resources are applied to multi-family residential buildings in practice and in which way water resources efficiency is evaluated when obtaining the certification, through theoretical analysis on the domestic and overseas Green Building Certification Criteria(GBCC), based on multi-family residential buildings in a bid to reduce the environmental load caused by indoor water use. As a result of seeking ways to improve the limitation of water resources evaluation in the domestic GBCC, I suggested a calculation program which evaluates the items of water resources in more objective and quantitative way. |
