The current progress in the field of Building Informa on Modeling (BIM) and the new possibili es facilitated by IoT (Internet of Things) pla orms could contribute to the stream of the integra ng improvement of the knowledge-based built heritage management. In this paper, ُthe concept of integra on of BIM and IoT would appear as a process of coordina on of all phases under a proper knowledge-based strategic approach. The op mal provided model would eventually be essen al to integrate common sub-processes grounded on the developed BIM-IoT principles/model. The eventual model has been conceptualized through the correspondence of BIM with WSN (Wireless Sensors Network) as the central management brain of the opera on and maintenance of the buildings referring to the sustainability concept and conducts as a Knowledge Management System (KMS).
