The paper ‘Radiative cooling and thermoregulation in the earth’s glow’ published on ‘Cell Reports Physical Science’ introduces an innovative approach to managing building temperatures by utilising materials that passively radiate heat to the sky and reflect heat from the ground. 

These materials, when applied to building exteriors, can effectively cool interiors in the summer and retain warmth in the winter without the need for conventional air conditioning or heating systems. 

The study shows that this method can lead to significant energy savings and reductions in greenhouse gas emissions. 

It also highlights the scalability and applicability of these materials, many of which are commonly used like plastics, making them suitable for both urban environments and areas with limited resources.
