As global temperatures continue to rise, the demand for cooling across buildings, infrastructure, and transportation is increasing significantly, driving higher energy consumption and carbon emissions. In response, governments and industries are accelerating the adoption of energy-efficient and low-carbon solutions.

To address these challenges, this technology introduces an advanced passive daytime radiative cooling (PDRC) solution in the form of high-performance optical films. Through spectral engineering, the material reflects the majority of incoming solar radiation while simultaneously emitting heat through the 8–13 μm atmospheric window into outer space, enabling net-zero energy cooling with sub-ambient performance. Unlike conventional cooling methods, this solution delivers rapid, energy-free surface cooling, achieving temperature reductions of up to 20–40°C under direct sunlight, with cooling power of approximately 100–150 W/m². Current product offerings include transparent films for window applications and non-transparent reflective films for rooftops and other surfaces. 

With a proven track record in Greater China and Hong Kong, the technology owner is seeking partners in Singapore for co-development and pilot deployment in hot and humid tropical environments. Ideal partners include building developers, construction companies, property owners, façade and roofing specialists, as well as warehouse operators. Companies in energy storage, cold-chain logistics, and energy infrastructure (e.g., solar PV operators) are also welcomed for performance validation and potential scale-up.
