This paper was presented at the 26th International Symposium on Industrial Electronics, held on June 19-21, 2017, in Edinburgh, UK.
The communication between different partners to handle the different tasks during the life cycle of buildings is far from being perfect. Fragmented engineering, lack of data consistency, insufficient system documentation or sensitivity for data sharing are only a few of many problems in this field that have not been efficiently handled through researches as well as in practice. This paper focuses on a deeper analysis of these problems mainly in the planning and engineering phases (they are the basis for all other phases) from both technical and economical point of view. An approach to handle these problems will be presented and thoroughly discussed.
