Technical Building Systems Solutions

This working group explores energy-efficient systems, concepts and technologies, which provide user-oriented indoor climate in an environmentally friendly way. As it takes an ideally adjusted system of architecture and technical building systems to achieve a sustainable, efficient indoor environment, the group develops solutions to optimally fulfil the users' requirements, such as thermal comfort, energy efficiency, occupational and operational safety. The group creates holistic planning approaches for new projects and for existing buildings, which offer maximum comfort while using only minimum energy input.

In addition, the working group focuses on the integration of structural, technical and function-specific measures in the field of central building control systems and building automation. To optimise building operation and to achieve a high level of energy efficiency in complex buildings, the different building services systems (such as heating, ventilation, cooling or lighting and shading systems) need to be adjusted and integrated in an overall system. The group develops components and control algorithms for this purpose. Special attention is attributed to the consistency in communications of bus systems and their implementation, allowing for virtual and laboratory testing of the components with regard to their integration in »third-party« systems. This allows developing methods for failure detection and diagnosis in buildings.

In the scope of a funding measure launched by the German Federal Ministry for Economic Affairs and Energy the working group recently created a singular test environment to investigate and advance integrated networks of technical building systems. Based on a hardware-in-the-loop approach, the platform comprises devices for heat and cold generation (CHP with coupled absorption chiller, gas condensing boiler, compression chiller, heat pump) which are linked to several consumer buildings by a local district heating network, thus allowing performing flexible tests on different combinations of systems. In connection with the implementation of the EU eco-design directive, current projects to determine and validate the system efficiency of combinations of systems are getting started. In close cooperation with industrial companies and associations, simple evaluation models for efficient systems combinations are being developed on the basis of comprehensive measurement series and coupled simulation models.

Climate Design

Creating an efficient and sustainable indoor climate solution requires a perfectly dovetailed integrated system that encompasses both architecture and building systems. The working group develops solutions to meet comfort specifications and all other user requirements.

“Climate adapted building design” means analyzing and establishing parameters for a building's outdoor climate, function, form, location, comfort specifications and usage requirements. This yields an integrated overall concept that includes environmentally friendly strategies for regulating indoor climates, such as the passive use of solar energy and natural cooling.

Systems Integration in Efficient Buildings

The research team works on integrated solutions for buildings to provide maximum comfort, health benefits and age-appropriate housing  while keeping costs reasonable and minimizing the use of energy.

To achieve these targets structural, technical and user-oriented measures have to be optimally adjusted with one another: The structure and quality of a building are mainly responsible for increasing energy efficiency. The right choice and optimized handling of efficient plant-specific components for heating, cooling, ventilation and natural lighting of rooms or buildings is of great importance. Based on social and user-oriented requirements, robust plant-specific systems and accordingly optimized operation schemes have to be implemented. The research team is also focusing on realizing these ideas for existing buildings.
