Physics World: Delignified wood could help cool down buildings

InventWood Featured in Physics World

A new passive radiative “cooling wood” that reflects infrared radiation could reduce the energy costs associated with cooling buildings by between 20 and 60%. The material, which is more than eight times stronger than natural wood, is made by removing the lignin from wood and then compressing the delignified structure.

“We conclude that the Southwest may be the area to benefit the most from this material to reduce energy consumption for cooling,” says Hu. “Indeed, UMD spinoff company Inventwood LLC in Maryland is now commercializing this technology,” he tells Physics World.
