Overheating has significantly increased building energy consumption worldwide. Passive Daytime Radiative Cooling (PDRC), capable of lowering its surface temperature below the ambient temperature without extra energy consumption, offers a promising solution to this challenge. Yujie Yang's PhD project concentrated on the potential energy savings from applying this technology to buildings. During his studies, Yujie developed a comprehensive model that considers various climate parameters for PDRC simulations and formulated methods to integrate the PDRC model with existing Building Performance Simulation (BPS) tools. However, it's worth noting that PDRC can augment a building's heating energy demand. To address this, Yujie Yang also investigated temperature-adaptive PDRCs to assess their efficacy in offsetting the increased heating energy requirement.

The PhD study was completed at Civil and Architectural Engineering, Faculty of Technical Sciences, Aarhus University.
