We propose to enhance the IFC information by adding functional facts to the spaces, i.e., information about the space usage (if it is a corridor, a reception, a coworking space, etc). Additionally, we propose to add information about the different types of alarm and security systems present in the built environment, specifically the security systems of the doors (e.g., key-lock system, card reader system and biometric system). This can allow the deduction of knowledge regarding the security restrictions of a space." . . . . "2019-11-07T12:47:11+01:00"^^ . .
