Reviewing 20 Years of CBE Data (07-29-20)

A Graham-lead team at the Center for the Built Environment, University of California, Berkeley, reviewed 20 years of data collected by the Center; their findings are available without charge at the web address noted below. The CBE researchers report that “One of the most widely used online POE [post-occupancy evaluation] tools is the Center for the Built Environment’s Occupant Survey. We analyzed data collected from this tool over the last two decades (>90,000 respondents from ~900 buildings) to summarize the database and evaluate the survey structure. 68% of the respondents are satisfied with their workspace. People are most satisfied with spaces’ ease of interaction (75% satisfied), amount of light (74%) and the cleanliness (71%), and most dissatisfied with sound privacy (54% dissatisfied), temperature (39%) and noise level (34%). . . . Roughly two fifths of building occupants felt the acoustic quality and thermal comfort were responsible for interfering with their ability to complete their work, and one quarter of respondents indicated the office layout was creating interference.”
