Perceived fit of different office activities - The contribution of office type and indoor environment

Office spaces are often examined using comfort-based measures. Another view is the need-supply fit, which emphasizes the fit of the space for different activities. Here the influence of office types and satisfaction with indoor environmental quality (IEQ) factors on different activities' perceived fit was examined with a large global dataset consisting of 82 315 respondents. The office types included private offices, assigned workstations in shared offices, assigned workstations in open-plan offices, team tables, and flex offices. The IEQ factors were estimations of satisfaction with thermal conditions, noise, air quality, natural light, and office lighting. The perceived fit was the estimation of workplaces' support for different office tasks classified into eight activity types. The largest proportion of respondents were dissatisfied with thermal conditions (30.7%) and noise (27.9%). However, only dissatisfaction with noise was strongly related to the perceived fit and explained alone 17% of perceived fit for concentrated work. All office types supported office activities well. Satisfaction with IEQ factors explained the perceived fit better than the office types. Satisfaction with IEQ factors alone explained 16 24% of the perceived fit depending on the activity type. Private offices were considered the best fit, especially for concentrated and confidential work as well as remote contacts. The study shows that the need-supply fit approach offers a slightly different perspective on office functioning than comfort-based approaches. Satisfaction with IEQ factors is crucial for functioning in an office. Special care should be paid to noise control especially with activities needing concentration, confidentiality, or special material.
