Important areas of development in the field of housing construction are to energy efficiency, improvement of the system of operation and maintenance of buildings, transparency in the operational performance of buildings for owners and investors. To obtain such benefits, it is necessary to develop a strategy for implementation of intelligent technologies and smart engineering systems to improve energy efficiency, automate operational processes and create an ‘intelligent’ profile of a building. The article presents a study of energy efficiency of buildings and justifies smart management of real estate objects, in order to save resources and timely respond to the decline in their operational qualities. In the modern conditions of market economy, when most of the housing stock is privately owned, it is necessary to create a modern economic and organizational mechanism for overhauls, reconstruction and modernization of building with the use of BIM technologies. The result of the overhaul and reconstruction works is the restoration and improvement of the operational characteristics of buildings. An overhaul or a reconstruction is advisable if the technical condition of the building has been compromised and effective operation and maintenance are impossible.
