Seoul intends to realize zero-energy buildings through the “Green New Deal,” which aims to transform buildings that account for 68.2% of greenhouse gas emissions into green buildings with high energy efficiency. For this purpose, a passive method of high airtightness and high insulation of the building is also important, but this may cause health problems such as chronic respiratory diseases and asthma in occupants in terms of indoor air quality. In addition, according to the World Health Organization (WHO) report, the risk of infection to others has soared to 40% as indoor and outdoor air is not circulated in the corona virus (COVID-19). In contrast, even with ventilation of 0.3 ACH (air change rate), the risk of infection fell to the 1/20th level. Therefore, balancing ventilation, which not only affects indoor temperature but also indoor air quality, is the most important aspect of promoting zero-energy buildings. Therefore, the correlation between the window opening behavior of occupants, the most common source of ventilation, and the external environment was analyzed. The amount of natural ventilation with the window opening behavior was analyzed by the carbon dioxide decay method; further, the ACH value of residential buildings was determined considering the physical condition of each residential building.
