TECHNICAL MANAGEMENT OF THE BUILDING AND BUILDING INFORMATION MODELING: DEFINITIONS
First of all, let’s go back to the concepts of BMS (Building Management System) and BIM (Building Information Modeling), acronyms that are sometimes misinterpreted. A BIM model is a graphic representation of data from the assets of a building (design and built environment data, technical installations, etc.); it makes it possible to establish what is called a building repository. The building management system is one of the information systems that automate the management of a service such as heating or lighting of the building; it contains a database of measurement points, alarms and time series. In other words, BIM makes it possible to visualize geo-referenced building data through a digital model (building scale), while the building management system collects and processes the data which will then make it possible to supervise and configure the management of the convenience services of the building (equipment scale).
BIM-BMS CONVERGENCE WITHIN THE DIGITAL MODEL
A smart building is a building capable of making the most of its data via a single repository. However, BMS, just like CMMS (for aspects related to building maintenance) or any other information system operate in silos, each based on a partial repository.
If the main evolution until now consisted of interconnecting a BIM viewer with a BMS or a CMMS, the real building revolution actually comes from the ability to converge these data from the virtual and physical worlds (via a single repository), to contextualize them within a single database (the digital twin) to allow cross-analysis (for example, compare the rate of use of a space with its average temperature), to distribute data to applications other than the BIM viewer and for orchestrating events between the different systems (for example, a malfunction of a machine located in a room allows both to generate the creation of a ticket in the CMMS and to make this room unavailable in the reservation tool). This is what the BOS SPINALCORE offers, by putting BIM at the heart of the project and using it as a single repository for all the systems, even offering the possibility of viewing it in 3D for better understanding.
