3DEMO - Safe and energy-efficient factories through
3D Emission Monitoring

Starting position

In the production halls of industrial companies, defined and constant ambient conditions are generally required which place high demands on the characteristics of the room air (e.g. temperature, humidity, air movement, chemical composition, purity with regard to particulate or gaseous emissions). Ventilation systems are used to create and maintain these environmental conditions. They determine not only the process and product quality, but also the occupational safety and working conditions of the employees and are relevant with regard to compliance with legal requirements. The continuous safeguarding of these environmental conditions is in conflict with the energy requirements of energy-intensive ventilation and air-conditioning systems, which account for a considerable proportion of the energy requirements of industry in Germany - depending on industry and the scope of consideration, approx. 10-40 %.


The 3DEMO project now has two main objectives: On the one hand it aims at the development of innovative service concepts based on 3D emission monitoring in factory buildings. On the other hand the development of the necessary technological components and their interaction to a cyberphysical system is in the foreground. These two main objectives are to be regarded as equivalent. The rapid development of microelectronics and sensor technology in the context of industry 4.0/Internet of Things offers the technical and economic potential to set up distributed sensor nodes in wireless communication structures in industrial environments.

3DEMO concept

The sensors distributed in the factory hall record the room air parameters, which are dynamically formed by internal loads of e.g. machines/plants as well as external loads (e.g. weather influences, particle concentrations). To further improve the spatial resolution, these sensor data are coupled in real time with CFD simulation, which is processed in a "service cloud", for example, depending on requirements. This creates, among other things, the basis for a demand-oriented, i.e. room- and time-related control of the air conditioning systems (AHU systems) and other elements of the technical building services equipment (BMS). In addition, 3D emission monitoring can be used to derive capacities for load management measures and load forecasts for energy-flexible operation of the air conditioning systems. Using innovative visualization concepts, this information can also be made available to employees in an understandable form, context- and target group-related. This temporally and locally high transparency of the environmental conditions, which are created by the cyberphysical system, in connection with the given savings potentials and benefits, offers numerous starting points for innovative service concepts to support the planning and operation of production or ventilation and air-conditioning systems or technical building services.
