New cement cools buildings by 5°C: a revolution in construction

Scientists from China and the USA have jointly developed a new building material that can help cool buildings during heat waves. This 'photon-structured cement' can lower the temperature inside rooms by 5 degrees Celsius, which brings significant energy savings in air conditioning. According to the researchers, the new material has a special structure that reflects visible light and allows infrared radiation to pass through.

The article published in Science Advances reveals that this material solves the drawback of conventional concrete, which only reflects part of the sunlight and heat. Scientists claim that the new cement could be particularly useful for construction in tropical and hot regions, where traditional building materials get too hot. Experiments showed that buildings made with the new cement remained significantly cooler inside compared to structures built with conventional material.
