This　paper　introduces　a　database　of　34　field-measured　building　occupant　behavior　datasets　collected　from　15　countries　and　39　institutions　across　10　climatic　zones　covering　various　building　types　in　both　commercial　and　residential　sectors.　This　is　a　comprehensive　global　database　about　building　occupant　behavior.　The　database　includes　occupancy　patterns　(i.e.,　presence　and　people　count)　and　occupant　behaviors　(i.e.,　interactions　with　devices,　equipment,　and　technical　systems　in　buildings).　Brick　schema　models　were　developed　to　represent　sensor　and　room　metadata　information.　The　database　is　publicly　available,　and　a　website　was　created　for　the　public　to　access,　query,　and　download　specific　datasets　or　the　whole　database　interactively.　The　database　can　help　to　advance　the　knowledge　and　understanding　of　realistic　occupancy　patterns　and　human-building　interactions　with　building　systems　(e.g.,　light　switching,　set-point　changes　on　thermostats,　fans　on/off,　etc.)　and　envelopes　(e.g.,　window　opening/closing).　With　these　more　realistic　inputs　of　occupants＇　schedules　and　their　interactions　with　buildings　and　systems,　building　designers,　energy　modelers,　and　consultants　can　improve　the　accuracy　of　building　energy　simulation　and　building　load　forecasting.
