Healthy Efficient Homes  LBNL is conducting a broad collection
of research activities to inform the setting of ventilation
standards that protect health and advance energy efficiency
goals. To this end, we set out to answer the following
questions.    • Which pollutants represent chronic and acute
health hazards from inhalation in residences?   • Can the health
risks and harm from these pollutants be quantified to facilitate
prioritization of these hazards?   • How can ventilation
contribute to mitigating exposures and ultimately the harm
caused by air pollutants in homes?   • How can we control indoor
air pollutant sources to cost effectively complement or reduce
the need for ventilation?   • How can air cleaning and
filtration be used to reduce in-home exposures to both outdoor
air pollutants and those generated in the home?   • How can the
required amounts of ventilation and filtration be provided cost
effectively while minimizing energy use?  The following is a
partial list of completed and ongoing Health
