A ZNE, or net zero... Read More
Whether it’s e-cigarettes or emerging heated tobacco products, the market for electronic nicotine delivery systems is booming. Most scientists agree that vaping is less harmful than smoking tobacco, but how much is known about the “clouds” they create? ETA’s Hugo Destaillats discusses the chemical composition of these complex aerosols in a... Read More
Most Americans don’t realize cooking can be a major source of indoor air pollutants, unless they’ve recently burned something on the stove. But studies have shown that cooking-related contaminants can cause health problems such as respiratory illness and asthma attacks.
To learn more, I spoke with Brett Singer, PhD, a scientist at Berkeley Lab who investigates indoor air quality. Recently, he measured the levels of pollutants emitted from gas... Read More
Ashok Gadgil redesigned a simple technology, the wood-burning stove, to help Sudanese refugee women cook more efficiently, thus sparing them from the dangers of gathering firewood far from camp.
In the developing world, sometimes the simplest technology can have the largest payoff.
That's the lesson learned by Ashok Gadgil, a UC Berkeley professor of civil and environmental engineering and Berkeley Lab researcher who was asked in 2005 to help... Read More

The sticky residue left behind by tobacco smoke can do worse damage than stinking up furniture and discoloring walls. Exposure to thirdhand smoke leads to biological effects on weight and cell development that could be damaging to one's health, according to new research led by scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).
The researchers found that newborn mice housed with smoke-treated cloths for... Read More
Emissions of methane—a potent climate-warming gas⎯may be roughly twice as high as officially estimated for the San Francisco Bay Area. Most of the emissions come from biological sources, such as landfills, but natural gas leakage is also an important source, according to a new study from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
The report by EAEI researchers Seongeun Jeong and Marc Fischer is the first to... Read More
Many residential and commercial buildings leak air like sieves, wasting up to 40% of their heating and cooling energy. The primary reason for this energy loss is gaps and holes that exist in buildings’ air ducts. Getting an airtight seal on every connection can be difficult; even with skillful installation and generous applications of mastic (the putty... Read More

Berkeley Lab scientists have been awarded $1.3 million to study health impacts of thirdhand smoke.
Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have been awarded $1.3 million for two sets of studies to better understand the health impacts of thirdhand smoke, the noxious residue that clings to virtually all indoor surfaces long after the secondhand smoke from a cigarette has cleared out.
The two three-year grants are from the... Read More
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
