This study provides basic data for implementing zero energy buildings. The targets were analyzed for buildings with buildings in the building energy efficiency rating of 1 ++ or higher. The target building is classified as a passive and active element. The passive element analyses thermal transmittance values for walls, windows, roofs, and floors. And the active element analyzed heating, cooling, hot water supply and new renewable energy. Based on the analysis results, the status of the building was reviewed through box-plot. also Renewable energy sources in solar and geothermal systems have calculated energy output. Most of the target buildings were rated below the minimum grade. To implement zero energy buildings, Improved insulation performance for minimizing the load of buildings and requires an active system design for optimum operation. Based on this study, we will conduct a study on the optimal design of passive and active elements for implementing zero energy buildings.
