As part of the CPER FORBOIS 2, an action was initiated by the CRAN in collaboration with the LERMAB to acquire and install in a set of buildings in operation (Campus bois in Épinal) a system for managing the energy and air quality of a complex building. This system includes, on the one hand, the instrumentation of the buildings necessary for measuring and monitoring energy consumption and air quality, and on the other hand a digital model of this set of buildings, connected to this instrumentation. The purpose of the research platform is to propose optimal control of the actuators of the set of buildings (heating, air conditioning, ventilation, shading, etc.) based on the state of this digital model and the use of the different building rooms (number of people, energy profile, weather forecasts, etc.) to optimize energy performance and user comfort. The demonstrator aims to develop BIM (Building Information Modeling) tools and AI-based prediction tools for SMEs, taking into account the entire life cycle of a building from construction, management, to its renovation. Two development tracks are currently being considered:
— Measurement and optimization of energy consumption: this axis consists, in the first instance, of equipping the wood campus with the instrumentation necessary to measure its energy consumption and, in the second instance, of implementing the technological means necessary to act on this consumption (actuators, HMI interfaces, . . . ).
— 3D building reconstruction for renovation: this axis aims to prototype (and even commercialize) software solutions for the 3D reconstruction of buildings from the acquisition of point clouds by terrestrial LASER scanner.
The demonstrator is installed within the Séguin campus in Épinal.
On the one hand, a set of sensors instrument six zones characteristic of the diversity of the uses of the campus buildings: office, classroom, library, machine hall, technical room, …
In each zone, sensors measure parameters influencing heat and material flows, and occupant comfort: temperature, humidity, CO2 level, position of openings, electrical consumption, opening of hot water radiator valves, presence of occupants, …
On the other hand, scanning equipment (LIDAR) is present to create and update 3D models. A software "modibuilding" has been developed to automatically extract architectural elements (facades, windows…) from point clouds.
The 3D models and sensor data are integrated and made available to researchers through a server hosting a digital model of the building, and a set of scripts ensuring the recovery and historization of data.
Finally, software has been developed to model and simulate the behavior of occupants, as part of a co-simulation integrating the thermal evolution of the building.
