. . . . "Regarding the built environment, in this paper the definition of a Panoptes building was given, as well as its formalization by using an ontology. Also, two types of populations in the Panoptes environment were defined, static and dynamic. Furthermore, we believe that a classification of smart building should be done due to the generality of the actual definition of smart building. This classification may be created by considering: the functionalities of the smart building, the devices utilize, or a combination of both. The third type of classification was applied by defining a Panoptes building as a smart building using only cameras and focusing in monitoring the activities of people. Moreover, we considered that applications concerning smart buildings should exploit the built environment information, specially the data obtained from the IFC. We also proposed to enhance the IFC information by adding functional facts to the spaces and information about the security systems in the built environment." . . . . "2019-11-12T12:34:11+01:00"^^ . .
