"Low carbon and energy-saving reflective thermal insulation ceramic foam composite board"
In recent years, extreme weather has occurred frequently worldwide. According to the World Meteorological Organization, temperatures in Asia continued to rise in 2022, making it the second hottest year on record. China has experienced widespread power shortage and restriction, and urban residents heavily rely on air conditioning to survive in the scorching heat. The consumption of cooling electricity has further exacerbated power shortages and carbon emissions. How to strike a balance between increasingly hot weather and carbon emissions is a severe challenges. An important pathway is to retrofit buildings to reduce energy used. In this project, a layer of highly reflective paint is applied to the surface of foamed ceramics with low thermal conductivity as the base material to improve the reflection of sunlight. Therefore, the double cooling of buildings are achieved by the thermal barrier effect of foamed ceramic matrix and radiational cooling effect of the coating. And the power consumption such as air conditioning is reduced. Due to its high diffuse reflectivity of sunlight, reflective thermal insulation foamed ceramic composite panels can be used as environmental background and photovoltaic power generation modules to provide added light energy supplement, as in the building integrated photovoltaics (BIPV). Compared with the common environment such as concrete and bricks, the power generation increase of photovoltaic panels about 3%~10% is achieved by using foamed ceramic composite panel. Consideration of the more green power generation in BIPV and less energy consumption , low-carbon, or even zero-carbon or carbon-negative is optimistically realized in the all life cycle of the building.

Our team has done two years of technology research and development and field visits from 2022 to 2024. The team leader has 8 years of experience in new material research and development, etc. Our products will develop the first production line in 2025
It is mainly concentrated in Guangdong Province and northwest China
We have applied the foam ceramic composite panels and examined the actual effect both in laboratory and outdoor. In summer, the outdoor practice has proven that, the temperature inside houses built with foam ceramic composite panels is 6-8 ℃ lower than outdoors, which can greatly save air conditioning power consumption. Meanwhile, when the composite panels are used as an environmental background, more than 4% green electricity are generated by photovoltaic modules compared with the concrete walls. Based on our computational model, the air conditioning usage can be reduced about 90 days per year, on the benefit of double cooling of the ceramic composite panels. And energy savings of 33 kWh/m2, CO₂ emissions reduce of 6.7kg/m2, as well as photovoltaic power generation increase of 2 kWh/m2 can be obtained. Our project shows significant energy-saving and carbon emission reduction effects, as well as attractive economic benefits.
