Open-plan office layout is commonly assumed to facilitate communication and interaction between coworkers,
promoting workplace satisfaction and team-work effectiveness. On the other hand, open-plan
layouts are widely acknowledged to be more disruptive due to uncontrollable noise and loss of privacy.
Based on the occupant survey database from Center for the Built Environment (CBE), empirical analyses
indicated that occupants assessed Indoor Environmental Quality (IEQ) issues in different ways depending
on the spatial configuration (classified by the degree of enclosure) of their workspace. Enclosed private
offices clearly outperformed open-plan layouts in most aspects of IEQ, particularly in acoustics, privacy
and the proxemics issues. Benefits of enhanced ‘ease of interaction’ were smaller than the penalties of
increased noise level and decreased privacy resulting from open-plan office configuration.
