Abstract

This study focused on the number of story to obtain zero energy apartment in Seoul through the intensification of energy performance of apartment in each stage and supply of solar energy generation. A 15-story building with four $85m^2$ households in each floor, the most common format of flat-type apartment in Korea was selected as the subject of study. The building energy representing zero energy was defined by five types of building energy (heating, cooling, hot water, ventilation, and lighting) based on the 'Building Energy Efficiency Rating Standard' of Korea and EPBD standards. It was assumed that the building's energy performance is enhanced in each stage, and the required energy was limited to the supply of solar energy that is highly applicable to the apartment among available new renewable energy. The five types of energy consumed by apartment in each stage were calculated based on the heat transmittance in each section of the building among the valued notified in 'Environment-friendly Housing Construction Standard and Performance.' For the energy required for heating and cooling, the primary energy consumption was calculated based on ISO 13790 and DIN V 18599 parameters. The number of apartment story at which the volume of solar energy generation and the volume of five types of energy required by the building are balanced off to zero was studied. The 'Building Energy Efficiency Rating System Operation Regulation' is evaluated by five types of building primary energy use. The number of story to obtain zero energy apartment through the solar generation on the roof and 50% of south spandrel generation is 22-story. According to the research, by the end of 2025 when zero energy is mandatory, 22-story apartment Is obtainable when solar energy generation is installed on the roof and the half size of south spanderal. Even 52-story apartment is obtainable when east and west wall are considered as well.
