US EditionSustainable cooling film could slash building energy use by 20% amid rising global temperatures
CHINA, JUN 24 – The biodegradable bioplastic metafilm reflects 99% of sunlight and reduces cooling energy use by up to 20% annually in hot cities, offering a sustainable alternative to conventional air conditioning.
- Scientists from Zhengzhou University in China, together with collaborators from an Australian institution, have created a biodegradable cooling metafilm that lowers surface temperatures without the need for electrical power.
- The development responds to rising energy demand for cooling and environmental concerns about carbon emissions caused by conventional air-conditioning.
- The metafilm reflects nearly 99% of sunlight, cools surfaces by up to 9.2°C during peak hours, and remains durable after prolonged UV and acid exposure.
- Simulations indicate that applying the metafilm may lower annual energy use in buildings by as much as 20.3% in hot climates like Lhasa, providing an eco-friendly alternative to conventional cooling methods.
- The researchers intend to expand production and investigate the use of the metafilm across various sectors, including construction, transportation, farming, electronic devices, and healthcare, to promote sustainable development.

HVAC company unveils futuristic 'ice battery' that could transform how we cool buildings — here's how it works
Ice is the simple source behind a new HVAC system that's helping thousands of buildings stay cool while reducing energy bills. Trane's thermal battery storage system leverages off-peak electricity rates to create ice, which is then used to help cool buildings throughout the day. This "ice battery" design is said to provide 40% energy savings over traditional air conditioning while lightening the load on the electricity grid, according to Inter…
City of Chelsea and Chelsea Housing Authority Install “Cool Roof” – Chelsea Record
Special to the Record Courtesy PhotoThe climate resilience project will protect the Chelsea Housing Authority’s most vulnerable residents – seniors and those with disabilities – by keeping them cooler in their apartments during extreme heat events. The Chelsea Housing Authority (CHA), in partnership with the City of Chelsea, has installed a white solar-reflective “cool roof” on one of its largest public housing buildings – the Margolis Complex,…

Bioplastic breakthrough: Sustainable cooling film could slash building energy use by 20% amid rising global temperatures - Scientific Inquirer
An international team of scientists has developed a biodegradable material that could slash global energy consumption without using any electricity, according to a new study published today. The bioplastic metafilm – that can be applied to buildings, equipment and other surfaces – passively cools temperatures by as much as 9.2°C during peak sunlight and reflects almost 99% of the sun’s rays. Developed by researchers from Zhengzhou University in …
