The interaction between heating and air conditioning technology and the building to be supplied is becoming increasingly important. The term "smart building" includes increasingly complex requirements for the transfer of benefits in residential and non-residential buildings. The dynamic behavior of low-exergy systems and their integration into the building physics present a major challenge when it comes to the seamless provision of thermal comfort with the highest possible system efficiency.
Planners of technical building equipment must meet these challenges in ever shorter planning phases. Existing software solutions for planning and simulation either only allow hourly resolutions for transient calculations or require a great deal of specialist knowledge in the field of simulation technology.
The aim of this research project is to develop a planning tool that enables a complete dynamic consideration of the processes in plant systems and building physics without specialist knowledge in the field of simulation technology. The basis for this is a simulation environment and dynamic models of building physics and building technology as well as controllers, which are integrated into a plant system in the standardized format "Functional Mockup Unit" (FMU) or as exported C code in an intuitive way via physical connectors. Another central element of the planning tool is an expert system that diagnoses and interprets errors that occur during planning (improper wiring, violation of validity ranges, numerical singularities, etc.) and processes them for the user. The results are evaluated using a prototypical visualization tailored to the requirements of planning offices. The development environment thus offers a complete tool chain for the design of TGA concepts.
