Building occupants are a valuable source of information for indoor environmental quality (IEQ) and its effects on health, comfort, satisfaction, self-reported performances, and building performance. There are no standardized methods to survey occupants. A brief literature review has been conducted to collect and describe features of IEQ questionnaires. Ten surveys have been identified and analyzed in terms of type of evaluation, objectives, investigated topics, number of applications, integration with physical measurements, questionnaire structure, types of questions and answers, length of time to complete, languages, and distribution and gathering strategies.
