According to the statistical data from the International Energy Agency, carbon emissions from the construction industry account for 40% of global carbon dioxide emissions. Among them, nearly 8.5% of the final electricity consumption is utilized for space cooling, and the increasing demand for building cooling has emerged as the fastest-growing factor in energy consumption. It is projected that by 2050, energy consumption for building cooling will increase by 83%. Thus, exploring passive building cooling technologies, reducing the usage rate of air conditioners, and enhancing the comfortable time of occupants indoors are the requisites of the era.

In recent years, the advent of new energy-saving envelope structure technologies has fundamentally diminished the heating and cooling loads of buildings, offering a novel thinking for reducing energy consumption in air conditioning. Within this context, the smart color-changing window technology represents a highly emblematic technique. Smart windows can adjust the absorption of indoor solar radiant heat in real-time and dynamically based on the light and heat requirements of buildings, thereby achieving intelligent regulation of building thermal loads. Thermochromic perovskite materials have garnered significant attention in the domain of energy-saving smart windows for buildings due to their near-room-temperature color-changing temperature, short color-changing time, high light transmittance, and solar radiation regulation capacity. Nevertheless, this material also presents certain issues: poor weather resistance, prone to the influence of humidity and moisture; poor film-forming property, leading to a relatively high optical haze of the smart window coating, which may potentially affect the clarity of vision. These problems fundamentally restrict the practical application and large-scale promotion of thermochromic perovskite smart windows.

To address the aforementioned challenges, Professor Zhiyin Cao, co-founder of Chuangleng Technology and from the School of Energy and Environment at the City University of Hong Kong, along with his team, in collaboration with the team of Professor Baoling Huang from the Department of Mechanical and Aerospace Engineering at the Hong Kong University of Science and Technology, have successfully developed a novel thermochromic perovskite smart window (MTP smart window). The inspiration for this research stems from the design of medical masks, featuring good breathability, high weather resistance, and low haze.
