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?

Reducing greenhouse gas (GHG) emissions, which result from the burning of fossil fuels, also reduces the incidence of health problems from particulate matter (PM) in these emissions.
A team of scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab), the National Institute of Environmental Health Sciences (NIEHS), RAND Corp., and the University of Washington, has calculated that the economic benefit of reduced health impacts from... Read More
EETD's Hanna Breunig has been named one of 16 Schmidt-MacArthur Fellows in the program's class of 2014.
Breunig is a graduate student researcher in the Sustainable Energy Systems Group's emerging technology analysis group, Environmental Energy Technologies Division, and a PhD candidate in the Department of Civil and Environmental Engineering at the University of California, Berkeley. She is one of 16 Schmidt-MacArthur fellows in the class of... Read More
Assessing Probability and Uncertainty for Smarter Decisions and Policies
In this first of a series of Q&As with researchers in the Environmental Energy Technologies Division, Michael Sohn talks about probability and uncertainty in modeling.
Michael Sohn is an environmental engineer working to understand how chemicals and energy are used in the world at various scales—global, state, and building. His research interests are in mathematical... Read More
For decades, California has used groundbreaking tools to collect and analyze emissions data from a variety of sources to establish a scientific basis for policy making. As its scope has expanded to include greenhouse gas (GHG) reductions, it has sought out similar tools to use to achieve the goals of legislation such as the Global Warming Solutions Act of 2006 (AB 32).
To support this effort, Lawrence Berkeley National Laboratory developed a... Read More
A team of researchers in the Environmental Energy Technologies Division led by Hanna Breunig has published a paper analyzing regional options for managing brine from carbon capture and sequestration projects. The research, described in a ... Read More
Using measuring techniques that combine video with devices measuring particulate matter, black carbon and nitrogen oxides in real time, scientists at the Environmental Energy Technologies Division (EETD) of Berkeley Lab have verified that policies designed to reduce the emissions of particulates from trucks driving onto the Port of Oakland have been effective.
The paper describing their results, by Timothy Dallman and Robert Harley of the UC... Read More
Scientists in Lawrence Berkeley National Laboratory's Environmental Energy Technologies Division (EETD), in cooperation with colleagues throughout the Lab, have formed a team to evaluate the impacts of low-carbon and energy-efficient technologies that are still in the laboratory. Development of these technologies is part of a Lab-wide effort called Carbon Cycle 2.0, focused on sustainable energy solutions such as advanced materials and... Read More
Recently, EETD's Thomas Kirchstetter, and Tim Dallman and Robert Harley of the University of California, Berkeley, presented the results of a study on the emissions of PM (particulate matter) and NOx (nitrogen oxides) from trucks at the Port of Oakland. The occasion was an August 4th hearing in Oakland, California, convened by Alameda County... Read More
"California's Energy Future - The View to 2050" looks a generation ahead at what's required to reach the goal of reducing the state's greenhouse gas emissions 80 percent below the 1990 level by 2050. Several researchers in the Environmental Energy Technologies Division participated in developing this study, the result of a multi-institutional partnership to examine energy futures to reduce California's emissions.
The report finds that the... Read More
Thomas McKone, Leader of the Environmental Chemistry, Exposure, and Risk Group of the Environmental Energy Technologies Division, has been quoted extensively in the news media on the transport and health risks of radiation from Japan.
McKone will be a speaker at the Western Occupational and Environmental Medical Association webinar on April 6 at 12:00 Pacific Time titled "... Read More
Michael Sohn, Staff Scientist and Leader of the Airflow and Pollutant Transport Group, EETD, is serving on a U.S. Environmental Protection Agency Science Advisory Panel, Office of Pesticide Programs. The purpose of the panel is to review a probabilistic approach to source-to-outcome health risk assessments.
Emissions of methane, a potent greenhouse gas, from local sources in California are higher than previously thought, according to direct measurements made by a research team led by Marc Fischer at Lawrence Berkeley National Laboratory's Environmental Energy Technologies Division (EETD). Attempting to pinpoint the source of the added emissions, the collaborative team, including EETD and National Ocean and Atmospheric Administration Earth System... Read More
Dan Rather Reports, a newsmagazine show airing on HDNet, interviewed Marc Fischer of the Environmental Energy Technologies Division for a segment about reducing greenhouse gas emissions through carbon offsets. Fischer's research focuses on measuring regional emissions of greenhouse gases through direct measurement. The show aired November 11.
An NAS report estimates the hidden costs of energy production and use in 2005 were $120 billion with the single largest expense attributed to health damage from air pollution associated with electricity generation and motor vehicle transportation.
