An event automation system controls building management systems (e.g. building automation, access control, and/or security systems of a building) for scheduled events. An occupancy module generates occupancy information for event spaces where events are scheduled via occupancy sensors installed at the event spaces. A building automation module instructs distributed devices of the building management systems to control the environmental settings of the event spaces based on the occupancy information and stored space, attendee, and schedule information. The event automation system also facilitates scheduling the events at event spaces of the building based on configuration information from an event organizer (e.g. invited attendees, start and end times, and activities to be performed at the event), required automation features for the event, location information and exercise preferences for the invited attendees, and/or aggregated usage information for the event spaces.
