A Study on BIM based Energy Efficient Design Improvement for Rural Standard Drawing and Specification in South Korea Focusing on Using Buffer-Zon

Throughout the world, global warming has been considered a severe problem, which has led to efforts being made for technical development to reduce greenhouse gases in the building sector. As more attention has been paid to energy consumption by residential housing in the building sector, policies and studies on domestic dwellings tend to focus on quality improvement and energy-efficient housing development rather than quantitative housing supply. Yet, policies and guidelines considering residential energy efficiency are inclined to focus on performance and lack in integrated consideration in connection with design. Hence, it seems necessary to compare and analyze design and energy efficiency and to study correlations between housing design and energy. Lately, BIM technology has been used in buildings domestically and proved reliable in respect of its features that enable overall comparison and prediction of housing design, performance and efficiency. The present study is to use the BIM technology to analyze energy consumption and the standard drawing schemes for rural areas to find ways to improve efficient design in singles housing sector and to suggest how to take advantage of buffer zones and how to improve housing design in favor of energy efficiency.
