Indoor Environmental Quality (IEQ)
4.13 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.

While the majority of the stadium is dedicated to the athletic field and seating, it is also home to building facilities and operational staff. The indoor environmental quality of their primary work areas was evaluated through a survey to employees, the results of which are shown here. Visitors' perceptions of the stadium have not been evaluated through this process.
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.
