Indoor Environmental Quality, Human Health, and Productivity

Faculty in the Penn State Department of Architectural Engineering conduct fundamental and applied research on the interactions between humans and the indoor environment to improve the health and productivity of building occupants. Research topics include the impact of improved indoor environment quality considering acoustical properties, including background noise and reverberation; lighting design aspects, such as spectral optimization; indoor air quality, such as characterization and control of particulates in the indoor air; and use of germicidal ultraviolet light to disinfect air and surfaces.

Research labs focused on this research area:
