As demand for low-energy buildings increases, indoor environment, and ventilation evaluation is becoming critical. However, it is difficult to find studies that evaluated complex factors other than mechanical ventilation, such as void, natural ventilation, IoT, and the number of occupants. Therefore, in this study, a total of seven scenarios were established based on four ventilation factors, and general buildings before remodelings and low-energy building after remodeling were analyzed based on three evaluation indicators (energy usage, discomfort time, and ACH). In conclusion, energy consumption was most affected by ventilation methods, and building performance also had ample influence that low-energy buildings had an average utilization rate of 30% compared to general buildings. Discomfort time was most affected by the ventilation method, which had RreliefF contribution was 42%, and natural ventilation was likely to be exposed to high discomfort time regardless of other ventilation factors. Finally, in the case of ACH, low-energy buildings did not meet the average minimum standard in all scenarios when only indoor temperature and humidity were considered as ventilation standards. Rather, ventilation in general buildings meets the criteria for ACH values, so it is necessary to consider whether ventilation can be performed simultaneously with temperature, humidity, and comfort.
