Performance Assessment of a Promising Radiative Cooler for Cool Roofs via Simulation

Radiative cooling is an age-old cooling practice that advantages in decreasing cooling energy requirements without power input. To apply this technology to the energy-efficient building industry, radiative coolers' performances should be assessed in advance. Using a simulation approach, the work in this study was to justify whether a promising radiative cooler would lead to the cooling energy reduction on a modelled roof in Beijing. The promising radiative cooler was reported to have the potential to achieve a temperature of 9.9 degrees Celsius below ambient temperature, which is a significant improvement over the results found in previous literature. Simulation outputs show that this material can lead to the cooling energy reduction on a modelled, 1000 square meters roof constructed in Beijing. This also implies that the promising cooler have a large potential of energy savings if they could be applied in Beijing.
