Abstract
Owing to the small thermal inertia of prefab houses, indoor thermal environment is poor and occupants are tormented especially under the high solar radiation. Retro-reflective materials can make it a reasonable choice to decrease radiation heat gain due to their high reflectivity for solar radiation. Comparative results show that the indoor air temperature of the prefab house by covering retro-reflectivity materials can reduce by more than 7°C, while the reduced value is close to 10°C for the peak radiant temperature and 7°C for indoor average radiant temperature. It shows retro-reflective materials have a significant effect on thermal performance improvement of prefab houses. Through the comparative study of different walls, it is found that the top, south and east walls are the better choices and that the north wall is the worst one to cover retro-reflectivity materials.
