Abstract

In office buildings, predicting the average thermal comfort of the staff is necessary for the architect to develop the building program during the schematic design phase. To improve indoor comfort, architects focus mainly on the structure and type of the building during the schematic design phase and try to save as much energy as possible on the surrounding environment. In this study, a traditional single atrium layout was compared to a multiple atrium configuration to assess their respective effects on the indoor thermal environment. Simulation software was used to calculate the Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfaction (PPD) indices using subjective assessments and physical measurements. The index is a comprehensive evaluation index that considers many factors related to human thermal comfort, starting from the basic equations of human heat balance and the psychophysiological rating of subjective thermal sensations. The results show that for most of the indicators, the building is more suitable for a multi-atrium layout. Improvements in the thermal environment were not significant in winter, but in summer, indoor thermal comfort was better in multi-atrium office buildings than in single-atrium office buildings in most climatic zones. Further exploration of the multi-atrium configuration reveals that the increase in atriums introduces more natural ventilation and natural light, significantly improving the indoor thermal environment and reducing energy consumption.
