SEMINAR: Ventilation and Occupants’ Activities Impact on Indoor Air Quality in New California Homes

Seminar Abstract 

The Healthy Efficient New Gas Homes project is studying ventilation and IAQ in California homes constructed since the 2008 building code required dwelling unit mechanical ventilation. The collected data include ventilation equipment characteristics, performance and usage; occupant activities that impact IAQ; perceptions of IAQ and comfort; and measurements of CO2 and air pollutant (fine particulate matter, nitrogen dioxide, formaldehyde) over 1 week. The study target is 65 homes. The first 16 homes all had supply or exhaust system and 2 of the 16 systems did not meet the standard requirements. In addition, local ventilation in the kitchen and in each bathroom, all of homes met the minimum standard requirement. Indoor pollutant concentrations were generally low.

Yang-Seon Kim is a postdoctoral fellow at LBNL. Her research area is building energy and environments, more specifically the indoor air pollutant reducing technologies associated with building energy savings. Her research started with particular contaminants (aerosol) in indoor air, and expanded to retail store environments and commercial building energy consumption. The main topic of her doctoral dissertation study was related to occupants' impact on the building energy consumption and improvement of building energy simulation results by using occupants' information. She also worked on occupants' perception in the retail store indoor environment. Currently, her work at LBNL is about residential building indoor environment study.

She holds a Ph.D. degree in Mechanical Engineering from the Pennsylvania State University and M.S. and B.S. degrees from Yonsei University in South Korea.
