Climate Change: Whitest Ever Paint Created By Scientists Could Replace Need For Air Conditioning

New paint makes it into the Guinness world records as the brightest shade of white ever.

Scientists at Purdue University say the paint is so white, it could eliminate the need for air conditioning units by reflecting heat away from buildings.

In a statement released via the University website, Professor of mechanical engineering at Purdue Univeristy, Xiulin Ruan said: “When we started this project about seven years ago, we had saving energy and fighting climate change in mind.”

Currently available market paints become warmer rather than cooler over time, something Purdue’s paint has been able to achieve. Purdue’s whitest ever shade reflects 98.1% of solar radiation and could be used for other utilities including roofing, server rooms and, what the research team believes will become a replacement for air conditioning systems.

In a recently released study, Purdue researchers say that covering a 1,000 square foot roof with the new shade may result in a 10 kilowat cooling power which Professor Ruan says is “…more powerful than the air conditioners used by most houses.”

The research was conducted in collaboration with Cooling Technologies Research Center at Purdue University and the Air Force Office of Scientific Research through the Defense University Research Instrumentation Program.
