How "ultra-white" paint can lower indoor temperature | Paint that can able to reduce home temperature by 4.5 °C | KNOW SCIENCE
Global warming is a serious issue. Emission of carbon dioxide and other global warming gas from industries, vehicles, and air conditioning systems will cause a rise in earth's temperature. To reduce the effect of global warming, scientist and researchers work hard to find alternative technologies. Recently, Prof. Xiulin Ruan (a Purdue University) and his team, developed a paint, called "ultra-white" paint. Source: Purdue University Normal white paints possess 75- 85% reflectance. Two materials were tested, CaCO 3 and BaSO 4 . Paint containing CaCO3 possesses 95.5% reflectance. The paint could cool up to 1.7 °C below the surrounding temperature. Other paint containing BaSO 4 and acrylic paint can reflect the sunlight at wavelength which enough to pass through the atmosphere. This paint possesses 98.1% reflectance. It lowers the inner temperature by 4.5 degrees °C. CaCO 3 absorbs more sunlight (4.5%) than BaSO 4 (absorbs 1.9% sunlight), ...
