...AND CHEAPER...:
New paint gives extra insulation, saving on energy, costs, and carbon emissions (Mark Golden, Stanford University, 8/14/23, Phys.org)
Stanford University scientists have invented a new kind of paint that can keep homes and other buildings cooler in the summer and warmer in the winter, significantly reducing energy use, costs, and greenhouse gas emissions.Space heating and cooling accounts for about 13% of global energy use and about 11% of greenhouse gas emissions. The new paints reduced the energy used for heating by about 36% in experiments using artificial, cold environments, according to a study published today in the Proceedings of the National Academy of Sciences. They reduced the energy needed for cooling by almost 21% in artificial warm conditions. In simulations of a typical mid-rise apartment building in different climate zones across the United States with the new paint on exterior walls and roofs, total heating, ventilation, and air conditioning energy use declined 7.4% over the course of a year.
