Standards body approves Berkeley Lab’s method to mimic natural soiling of roofing materials.
Cool roofs can help keep buildings cool, thus lowering the building’s energy use, while also mitigating the urban heat island effect by reflecting sunlight away from buildings and cities. But as cool roofs age and get soiled, how much of their reflectance do they lose?
A collaboration led by scientists at Lawrence Berkeley National Laboratory (Berkeley... Read More

An excerpt from a U.S. Department of Energy blog:
"...dramatic changes are occurring in our nation’s energy mix, many of which demand a more technologically advanced electric grid. Increasing use of renewable energy sources, risks of cyber and physical attacks, and aging infrastructure create uncertainty of the current grid’s long-term ability to provide the services demanded of it. These include distributing and storing clean energy, enabling... Read More
