Buildings, particularly their envelopes and environmental control systems, are critical at the intersection of sustainability, climate, and human well-being. These systems interact with external weather conditions to regulate the indoor environment, influencing energy consumption, greenhouse gas emissions, and occupant health.

A core focus of our research is understanding and leveraging the connection and the conversion between photometric and radiometric properties in building physics. This fundamental linkage underpins key phenomena such as the photothermal effect, fluorescence, visual-thermal interactions, and solar-thermal impacts. These insights inform applications like: thermal and optical behavior of building envelopes, influence of facades on outdoor thermal environments, indoor environmental health under extreme weather conditions, personalized indoor comfort, etc. Our research combines experimental, numerical, and subjective methods. Additionally, we develop innovative models, design strategies, and computational tools to advance this field and support our investigations.
