Lawrence Berkeley National Laboratory is seeking participants for a study of air quality in California homes. The study is being conducted by scientists in the Environmental Energy Technologies Division of Berkeley Lab. This project is funded by the California Energy Commission and is focused on homes with natural gas appliances. Individuals who are selected to participate and complete the requirements of the study will receive $75 and free... 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 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
The Healthy Zero Energy Buildings (HZEB) website has made its debut.
The HZEB research program's goal is to develop the information needed for scientifically-sound commercial building ventilation standards that balance energy efficiency objectives with the need to maintain acceptable indoor air quality.
Zero (net) energy buildings have a net energy consumption of zero over a typical year. The California Public Utility Commission and the... Read More
Buildings are responsible for a large fraction of total U.S. energy demand and buildings are replaced slowly. About one third of the U.S. population lives in multifamily buildings. The residents of multifamily buildings often have below-average incomes and they are sometimes exposed to high levels of potentially harmful indoor contaminants. The U.S. is embarking on a program of aggressive energy retrofits in homes, with a substantial focus on... Read More
Another reason for including asthma on the list of potential health risks posed by secondhand tobacco smoke, especially for non-smokers, has been uncovered. Furthermore, the practice of using ozone to remove the smell of tobacco smoke from indoor environments, including hotel rooms and the interiors of vehicles, is probably a bad idea.
Nicotine in third-hand smoke, the residue from tobacco smoke that clings to virtually all surfaces long after a cigarette has been extinguished, reacts with the common indoor air pollutant nitrous acid to produce dangerous carcinogens. This new potential health hazard was revealed in a multi-institutional study led by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab).
Research conducted at the Department of Energy's Lawrence Berkeley National Laboratory suggests that operating buildings more energy efficiently could have benefits for the health of occupants and, surprisingly, also for their comfort.
The researchers, Mark Mendell and Anna Mirer of Berkeley Lab's Environmental Energy Technologies Division, analyzed data collected from 95 air-conditioned office buildings across the U.S. The data had been... Read More
