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... Read more

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).... Read more
