Energy consumption behaviors and the potential of natural ventilation emission reduction in residential building

China is the largest Carbon Emissions country in the world. The data analysis and simulation of the sampled residential buildings reveals that there exists a large gap between the monitoring data and energy simulation. Based on the thermal comfort theory, we further explored the relationship between the energy consumption behaviors of residents and building ventilation emission reduction. This study constructed a questionnaire to analyze the use habits of existing residential buildings and equipment. The results show the range of suitable outside temps. In this paper, the findings of the survey were combined with the probability of summer outside temp range profiles to derive the thermal comfort satisfaction of the sample population. In the summer high temperature environment, natural ventilation can help to reduce indoor temperature and reduce the concentration of pollutants in the indoor air, thereby improving indoor air quality and reducing energy consumption. The findings can evaluate the emission reduction potential of natural ventilation. The study provided directions for the implementation of low carbon natural ventilation in residential buildings: natural ventilation can be used to reduce residential energy consumption and carbon emissions, reducing the need for mechanical ventilation. This enables environmentally friendly and sustainable buildings and uses renewable energy sources such as solar and geothermal energy as an energy supply. In addition, the study examined the emission reduction potential of natural ventilation measures in the summer temperature range of 26 degrees C to 28 degrees C, which could reduce carbon dioxide emissions by 1.61 kg per square meter.
