| Global warming and climate change, primarily driven by CO₂ emissions from building energy consumption, pose significant environmental challenges. This study investigates the energy performance of a single-family residential building in Jinan, China—a city characterized by a temperate monsoon climate—using simulation-based methods. The baseline building model was developed in DesignBuilder, leveraging the EnergyPlus engine to estimate annual electricity, heating, and cooling demands. To enhance passive energy efficiency, Phase Change Material (PCM), specifically InfiniteR29, was incorporated into the external walls and roof. The impact of PCM integration was evaluated in terms of envelope heat flux, overall energy loads, and indoor air temperature regulation. Results indicate that the inclusion of PCM reduces annual heat flux through the building envelope by 19.7%, leading to reductions of 12.7% in heating load and 45.6% in cooling load. Furthermore, PCM application significantly moderates indoor temperature fluctuations during extreme weather conditions, achieving a peak temperature reduction of 2.4°C during summer and exhibiting a thermal lag effect. These findings confirm that properly selected PCMs can substantially improve envelope thermal stability, lower energy consumption, and enhance passive building performance in climates with substantial seasonal and diurnal temperature variations. | ||
