A color developed by Egyptians thousands of years ago has a modern-day application as well – the pigment can boost energy efficiency by cooling rooftops and walls, and could also enable solar generation of electricity via windows.Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue... Read more

Today, electric vehicles (EVs) make up just a small part of the U.S. road fleet, but they are gaining ground in some regions. While EVs hold promise for lowering costs and air pollutant emissions from auto travel, among other benefits, their growth raises questions about the changes needed to support this transition. How much charging infrastructure will be needed, and what role should utilities... Read more

A deep understanding of energy use behavior by occupants in buildings is crucial to the design and operation of buildings to achieve low- or zero-net energy goals. Currently, occupant behavior is under-recognized, compared with the conventional technological solutions, and over-simplified in the design, construction, operation, and retrofit of buildings. Occupant behavior in buildings includes:The... Read more
