Programme Highlights
With the development of the global economy, the energy consumption of air conditioning systems has become a significant topic in global energy policies and climate actions. In subtropical Hong Kong, this issue is particularly pronounced due to its hot and humid climate, leading to a high prevalence of air conditioning systems and substantial energy consumption. Therefore, the development of energy-saving technologies for air conditioning systems, especially green building technologies, holds significant importance in alleviating global climate change and energy crises. Against this backdrop, this presentation focuses on introducing a novel energy-saving technology that combines passive radiative cooling with thermochromic smart windows.
The core of this technology lies in using high-performance passive radiative cooling materials to cover the roofs and exterior walls of buildings. These materials can reflect most of the heat from the sun while emitting mid-infrared radiation to the cold environment of outer space, achieving an effective "electrical-free cooling" effect. Furthermore, coupled with thermochromic smart window technology, the windows can automatically adjust their color and transparency based on external temperature changes, intelligently regulating the heat gain and loss through the windows to maintain a comfortable indoor environment throughout the year.
Additionally, we delve into the cutting-edge applications of these technologies in the field of architecture and energy policy formulation. By leveraging the combined application of these innovative technologies, we not only can significantly reduce building energy consumption but also propel the advancement of green building technologies, offering new ideas and solutions for global efforts in combating climate change, promoting sustainable economic development, and achieving carbon neutrality goals.
