IEQ, Building Type, and User Experiences (10-29-21)

Woo and colleagues assessed indoor environmental quality’s (IEQ’s) effects on workplace user experiences.  They collected data from 7 office buildings and report that “Three types of buildings were included in this study: ‘Heritage listed’ (c.1880–1890s), ‘Conventional’ (c.1960–1980s) and ‘Modern’ (post 2000) office buildings. Although the measured IEQ conditions were relatively good with no significant fluctuation across the selected buildings, the discrepancy between objective IEQ data and subjective occupant evaluations was noted. The Modern building type designed with fully double-glazed façades showed the highest levels of overall comfort and satisfaction and perceived productivity, whereas the Conventional building type constructed during the late 20th-century period, notable for deep floor plates, had the lowest. The heritage listed type buildings had lower window to wall ratios, yet displayed improved occupant satisfaction across all IEQ areas over the conventional type buildings. . . . Subjective evaluations do not seem to be always correlated to the corresponding indoor environmental parameters.”
