The survey must be distributed to regular building occupants. Examples are employees, volunteers who regularly use the building, residents (including residents of a dormitory), primary and secondary school students, hotel guests, and inpatients. Visitors are encouraged to be surveyed, especially if the daily average is greater than the number of regular building occupants. Examples of visitors are retail customers, outpatients, volunteers, and higher-education students. See page 20 of the LEED v4.1 O+M Beta Guide for additional information on occupancy types.
