Abstract
There is much research on zero energy buildings. In this paper, technologies and policies to improve the building energy efficiency of zero energy buildings are presented. The zero energy building certification system in Korea is introduced, and the evaluation is carried out based on the energy self-reliance rate that enables zero energy buildings. Zero energy buildings are able to minimize energy consumption due to the application of highly efficient building materials and equipment technology. In this research, to increase the prevalence of zero energy buildings in Korea, the authors propose a zero energy building technology package. Using a passive and active technology package, we confirmed the necessity and detailed requirements of each technology parameter. We analyze and classify Korean building material testing methods and performance standards, and propose passive and active technology packages, modules, material performance testing methods and minimum requirement performance standards. Finally, this study proposed a table presenting the test methods, standard and minimum value of performance. By these results, the authors confirmed the effectiveness and availability of passive and active technical packages.
Highlights
The demand for zero energy buildings is increasing in order to reduce the energy consumption of buildings, Technologies and policies to improve building energy efficiency for zero energy buildings are presented, and there is much research on zero energy buildings
In order to set up a zero energy building, the authors confirmed the conventional concept of zero energy building introduced in Korea and proceeded with research based on the existing research results
We proposed a package of passive and active technologies to facilitate the spread of zero energy buildings that suit Korea’s situation through the application of appropriate building materials and building equipment
Summary
The demand for zero energy buildings is increasing in order to reduce the energy consumption of buildings, Technologies and policies to improve building energy efficiency for zero energy buildings are presented, and there is much research on zero energy buildings. Since zero energy is achieved by producing and supplying renewable energy, it is difficult to disseminate zero energy buildings due to an increase in construction costs compared with general buildings as a result of the materials and facilities added. In Korea, the performance prediction is managed at the institutional level by evaluating the energy efficiency of the building, and the designer predicts the energy requirement amount and the primary energy requirement by utilizing the certification program ECO 2 (v20170122, Korea energy Agency, Korea) in other parts written as ECO2–us a consistent style Since these design programs can derive different results according to the input level of the user, the program generates a difference in the analysis result if there is no same input value by the same user. The results of this research can be utilized to build an actual zero energy building
