Where did the 7-point scale requirement come from? We have had our documentation questioned in reviews because we did not use this scale.

I think this subject has been discussed before but I can’t find the answer. How many percent of building occupants must answer the survey for it to be a valid result? Is there a limit, or should I myself determine if I need more people to answer the survey? Or is it enough to let everybody get a chance to answer, but then only receive a certain amount of answers? Thank you!

As far as I understand, for LEED NC there is no requirement for a specific number of people to respond to the survey. This may be different if you are pursuing LEED EBOM.

Thank you Emily! I'll just go with letting everybody have a chance to answer the survey, getting as many answers as I possibly can. But there seems to be no exact target number of answers required.

There is no minimum percentage requirement for the number of respondents to the survey. It is human nature that people who are displeased are most likely to speak out. The fewer the responses greater the likelihood more than 20% are dissatisfied and corrective action is required!
