N2 - Cool materials hold significant importance for building energy conservation, as their high reflectivity and emissivity characteristics can notably reduce summer energy consumption. This study conducted a scaled outdoor experiment to investigate the impact of using cool materials on the roof and building façades of different floors on the building surface and indoor temperature. The results indicate that, due to the shading effect between buildings, higher floors show better energy-saving performance when using cool materials on building façades. Specifically, using cool materials on the top floor resulted in an average reduction of 3.4 °C in the daytime for the south façade. For indoor temperature, the building façades of the top floor using cool materials showed an average reduction of 1.9 °C, while the building façades of the first floor only decreased indoor temperature by 0.5 °C. In general, the effectiveness of cool materials is better for the building surface receives more solar radiation.
