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 absorbs visible light, it then emits light in the... 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 play in developing it?
A new report from Berkeley... 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 presence of people in spaces and movement... Read More

Evaluating buildings as a group, rather than individually, can help optimize energy savings in cities. To aid this effort, the Energy Technologies Area’s Tianzhen Hong has introduced CityBES, a data and computing platform that can assess energy efficient retrofits for sets of properties and visualize their performance. He... Read More
Scientists said they were experimenting with using white paint over black asphalt as a way of cutting temperatures in the Phoenix area. Ronnen Levinson of the Energy Technologies Area said it could possibly reduce the heat island effect, a term given to urban areas that are hotter than nearby rural areas.

Berkeley Lab-led study suggests early exposure to thirdhand smoke may lead to greater health risks later in life.
Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) identified thirdhand smoke, the toxic residues that linger on indoor surfaces and in dust long after a cigarette has been extinguished, as a health hazard nearly 10 years ago. Now a new study has found that it also increases lung cancer... Read More
Universities across the United States have set ambitious goals to shrink their carbon footprints, including the University of California, which launched its Carbon Neutrality Initiative in 2013, aiming for carbon neutrality by 2025.
