Abstract: Both phase change material (PCM) and cool paint (CP) are effective passive strategies to improve thermal comfort and decrease energy consumption. In this work, eight typical cities were selected to represent different climates: five in China and three in Europe. According to the cooling/heating energy consumption, the cities were divided into different categories. PCM and CP + PCM were applied to the roof, and the phase transition temperature and thickness of PCM were analyzed. In cities with lower heating energy consumption ratio, PCM was inferior to CP + PCM. In other cities with relatively higher ratio, PCM was superior to CP + PCM. When PCM was coupled with CP, the optimal phase change temperature may change, and the influence of the phase change temperature was further weakened. With increasing PCM thickness, the energy consumption constantly decreased, but the peak load range decreased first and then remained unchanged. There was the minimum PCM thickness and the corresponding optimal phase transition temperature to reach the lowest peak load range, which could be used to select more energy-saving and economical PCM. This work provided valuable information for the design, preparation and optimization of PCM and the combination of PCM and CP according to corresponding energy consumption characteristics.
