Abstract: Techniques for controlling access to zones of a building. The techniques include determining with a computing device configured to regulate access to a zone of the building, at a time and responsive to a request to access the zone of the building received via an access control interface, whether a user is allowed to access the zone of the building; and in response to the computing device determining that the user is not allowed to access the zone at the time, receiving, via the access control interface, a request to permit access to the zone at the time; determining, with the computing device and at the time, whether to permit access to the zone based on one or more criteria; and outputting a result of determining whether to permit access to the zone.
