IEQ
Indoor Environmental Quality (IEQ)
The project specified low-VOC and formaldehyde-free products. Stained concrete was selected in lieu of carpet throughout. Also, physical activity is encouraged as there is no elevator in the building.
4.63 IEQ Satisfaction Score for Living Units
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 Living Units
The table below shows the mean satisfaction score for each IEQ category.

Overall Facility Ratings
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).

Living Units97%51%
The building houses up to 72 undergraduate students in four wings and includes suite-style housing, with four-person suites (with single and double occupancy rooms), four floor lounges and kitchenettes, a central lounge, patio, and study space. The indoor environmental quality of these living units was evaluated by the student residents.
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.
