Researchers estimate that those of us in developed countries spend 90 percent of our time indoors, which means that most of the time we are breathing air polluted by emissions from indoor sources. Providing more outdoor air ventilation can improve indoor air quality; however, energy is needed to heat, cool, humidify or dehumidify, and sometimes filter the ventilation air brought indoors from outdoors. Studies have shown that about 10 percent of... 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 U.S. Department of Energy has released six fact sheets to assist American Reinvestment and Recovery Act grantees and end-users in benchmarking energy efficiency upgrade costs and expected annual savings. 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.

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.
