Abstract

Cool roof with high solar reflectance and high emittance has been demonstrated as an effective way to mitigate heat gain from buildings. The newly proposed metamaterial based radiative cooling surface (MRCS), has an average daily cooling power of 110 W.m-2, shows high technical potential for the application in buildings as cool roof. The single-family houses are excellent end users of MRCS roof account for the relatively low cooling load but high ratio of roof area to floor area. To investigate the cooling performance of MRCS roof, three kinds of roof (i.e., MRCS roof, shingle roof, and light-colored roof) are employed in a two-floor single-family house. The cooling benefit of MRCS roof is analyzed with EnergyPlus. The results show that the annual cooling electricity consumption of the house with MRCS roof can be reduced by 15.8% and 8.6% compared to the house with shingle roof and light-colored roof, respectively.
