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
Current standards for U.S. offices require approximately 8 liters per second (L/s) of outdoor air ventilation per person. Providing twice as much ventilation would reduce sick building syndrome symptoms (SBS) and absences, improve work performance, and provide billions of dollars in annual economic benefits in the U.S., according to a recent study from the Lawrence Berkeley National Laboratory (Berkeley Lab).
A second study found that four... Read More
A new policy brief on the value of energy performance and green attributes in buildings, authored by Elizabeth Stuart, is available. Labels, certifications, and rating systems for energy efficiency performance and "green" attributes of buildings have been available in the U.S. for over 10 years, and used extensively in the European Union and Australia for longer. Such certifications and ratings can make energy efficiency more visible, and could... Read More

The fact sheets are directed at municipal, state, and federal government buildings, healthcare facilities, universities, colleges, and K-12 schools. The fact sheets provide information on the typical range of project installation costs,... Read More
Despite a trying year in which wind power capacity additions declined significantly compared to both 2008 and 2009, the U.S. remained one of the fastest-growing wind power markets in the world in 2010—second only to China—according to a report released today by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab).
A paper by William Fisk, Anna Mirer, and Mark Mendell has received a "best paper" award from the editors of the journal Indoor Air.
According to the citation, "Quantitative relationship of sick building syndrome symptoms with ventilation rates," was "one of the top papers published in the journal during the years 2008-2010."
The authors were honored at one of the plenary sessions of the Indoor Air 2011 conference, which takes place this... 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.

As China's economy continues to soar, its energy use and greenhouse gas emissions will keep on soaring as well—or so goes the conventional wisdom. A new analysis by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) now is challenging that notion, one widely held in both the United States and China.
New research by the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory finds strong evidence that homes with solar photovoltaic (PV) systems sell for a premium over homes without solar systems.
