Within the Dutch AEC domain government policies demand increasingly from construction projects, that they have to be implemented by performance based contracts. Because currently the number of such projects of the Dutch government in the Operation and Maintenance (O&M) phase increases, efficient contract management by the Dutch government is becoming more crucial in checking if the actual building performance complies to the agreed output specifications (OS). At the same time more heterogeneous non- geometric data is being produced in the O&M stage than ever before. Examples are: energy usage, indoor climate data, utility information, occupancy patterns, weather data, scheduling software, financial control etc. From literature study and conducted interviews with several companies, it has been found that often there is little interaction between these sensor data silos. However, cross- domain sensor data is seen as essential to understand the performance and optimize the operation of a building (by Facility Management) to ensure it is meeting the requirements of the organization/occupants. In short, building owners require more from their assets while the need to synchronize heterogeneous data sources become thereby more prevalent.
