Scientists have developed a paint that reflects more than 98 per cent of sunlight, which they say makes it more effective than some air conditioning units. Its energy-saving credentials could help to tackle the climate crisis

US engineers have created a paint so white that coating buildings with it, they say, could one day slash the need for air conditioning. Reducing energy usage in buildings is vital to tackle the climate crisis.

Purdue University, in Indiana, built on efforts to develop a ‘radiative cooling paint’ that go back 50 years. 

After six years of research and after studying more than 100 materials, they have developed a paint so effective at reflecting sunlight, that it chills surfaces to below surrounding ambient temperatures.
