Indoor Environmental Quality (IEQ)
5.55 IEQ Satisfaction Score for Offices
This score indicates the users’ mean satisfaction with the indoor environmental quality in the building’s primary spaces. It is expressed on a Likert-type scale from 1 (very dissatisfied) to 7 (very satisfied). The score is derived from the results of the Sustainable Post-Occupancy Evaluation Survey (SPOES) by averaging the score from each of the IEQ categories in order to fairly represent overall satisfaction with the physical environment.
IEQ Categories for Offices
The table below shows the mean satisfaction score for each IEQ category.

Overall Facility Ratings by Employees
This graph shows the users’ ratings (as means and standard deviations) of the overall facility, including the site, building, and interior. The values indicate user satisfaction, perception of their performance, and perception of their health in relation to the facility. They are expressed on a Likert-type scale from 1 (facility hinders satisfaction/performance/health) to 7 (facility enhances satisfaction/performance/health).

The Bell Museum includes program, exhibit, and planetarium spaces; lobbies and support facilities; and office and staff support space. Storage, fabrication space, and mechanical and electrical equipment are contained within the story below grade. This case study shows results from a survey of employees regarding the indoor environmental quality of their primary workplaces, which include private offices, enclosed shared offices, cubicles with low partitions, benching (a long worktable with multiple workspaces), and a desk in an open office or public space (reception) without partitions.
Reports
The Sustainable Post-Occupancy Evaluation Survey (SPOES) is a self-administered, Internet-based questionnaire developed to assess human outcomes in indoor settings. The survey was completed by the user group of the primary space and analyzed by the B3 Post-Occupancy Evaluation team. The SPOES reports document user satisfaction with the physical environment as related to various indoor environment quality criteria, such as lighting, thermal, and acoustic conditions.

See the B3 Post-Occupancy Evaluation website for more information.
