The final goal of the project is the development of a method for the systematic design of cost-optimized, predictive control strategies for complex energy networks in city districts.
Construction products can pose a risk to the environment and health due to their pollutant content or releases. In the BIMpeco project, workflows and data structures for digital information management of this environmentally relevant product data are developed. For this purpose, the new ISO standards ISO 23387 and ISO 19650-1 are tested and synchronized with established process flows. The project results will be made available on an open-source basis and can be integrated into any Common Data Environment (CDE) that complies with the standards mentioned. The BIMpeco project is the first to lay the foundations for product information management of environmentally relevant properties in the CDE, covering the entire lifecycle and supply chain.
Symbiose-4-I&C - Optimal decentralized hybrid storage technologies among different energy systems -4-Industry and Commerce
The project Symbiose-4-I&C analysed the coupling of existing energy networks/-carriers, established on centralized energy network nodes or directly next to a consumer (households, industry and commerce) and the benefits of applying decentralized storage technologies. The optimal position, dimension and the right storage and conversion technology and an optimal energy wide operation of larger consumer groups were estimated for an urban model region.

The central goal is the development of a mobile application that enables the energy optimization and planning of buildings, neighborhoods and higher-level energy systems through the participation of the user and the user as a new source of data and information. The development of the application is strongly transdisciplinary and integrates mathematical methods of simulation and optimization as well as psychological aspects of user behavior in order to develop new business models and open up new markets.
This project aims for feasible low-cost solutions, which allow residents of multi-party houses, with special focus on social housing to profit and participate in the energy transition process and associated trends (e.g. community generation units, exploitation of flexibility). The results of the project are low-cost concepts and business models of community generation units and utilization concepts, tested for their feasibility in a social housing complex. These concepts are based on special requirements of different lifestyles in low-income households and take the framework of social housing such as tenant fluctuation into account.
BIM4BEMS explores use cases that represent the usage of building information models (BIM) in combination with building energy management systems (BEMS) during operation. This enables the interaction between BIM and building management systems (BMS) which improves the analysis and visualization of inefficiencies in facilities.
