Indoor Environmental Quality Related to Occupant Satisfaction and Performance in LEED-certified Buildings

The purpose of this study was to identify whether the indoor environmental quality design criteria: office layout, office furnishing, thermal comfort, indoor air quality, lighting, acoustics, and cleanliness and maintenance in relation to the overall workspace for LEED ® -acreditation, could significantly affect occupants’ perception of their overall workspace satisfaction and their work performances. Occupants’ self-assessed satisfaction and performances were measured and these were correlated with occupants’ satisfaction and performances in their overall workspaces in 15 LEED-certified buildings in the US. The findings showed office furnishing quality has a significant impact on occupants’ satisfaction and performances; and indoor air quality affected only the occupants’ performances
