Entwicklung und praxisnaher Test der Performance von Gebäudekomponenten mit PCM in Demonstrationsobjekten (PCM-Demo)

Passive cooling and PCM together

Construction systems with integrated phase-change materials (PCM) can store a high degree of heat at room temperature. They can be used to regulate the temperature of rooms in an energy-efficient manner, even without active systems. As part of this research project, materials, components and systems based on salt hydrates were developed, promising applications were identified, and various systems implemented and tested as pilot projects.

Membrane constructions for building refurbishment

People will need to grow accustomed to this term: “textile architecture”. Buildings such as the Munich football stadium or the swimming pool building in Beijing demonstrate new design and construction possibilities using textile architecture. At the same time, the innovative, lightweight and flexible structures made using sheeting or textile fabrics also allow buildings to be energy-optimised. Now solutions for the energy-oriented refurbishment of buildings are being developed and tested in a research project.

Precast concrete units with vacuum insulation

Precast concrete units play an important role in the building trade. This project included the development of all-purpose concrete facade elements with integrated vacuum insulation. Prefabricated room-high elements are used to construct slim facades with excellent heat insulation characteristics that are suitable for use in passive houses.

Second-generation vacuum insulation

In this research project, a production process for a new type of vacuum panel has been developed. Loose silica powder can now be directly processed to form vacuum insulation panels. This enables special shapes to be realised such as vacuum panels with continuously stepped profiles or cylindrical, curved vacuum elements. The new vacuum insulation panels have already been successfully tested in practice in various buildings.

Design study for the new frame structure with triple insulation glazing

Thinner heat insulation with new window and facade constructions

The heat insulation requirements on buildings will only continue to be tightened. For exterior walls with heat insulation, this is basically not a problem. But for windows and facades it is conceivable that in a few years the requirements will only be met with triple-glazing or with vacuum-glazing which may be available by then. A research project will now develop particularly low thermal bridging constructions for the integration of extremely good thermal insulating and vacuum glazing for thin framework and facade structures.

Industrial and commercial buildings

Workshops for handicapped people

The workshops for handicapped people in Lindenberg (Germany) represent a good example of consideration and consistent implementation of energy aspects from the very onset, and this with reasonable costs. But at the same time, the real objective always remained in focus, namely to equip the rooms to suit the occupants and their special needs.

Next Step: Vacuum insulation glass

Vacuum instead of inert gases - with this technological development, glazing could take another great developmental stride. However, at 10 tonnes per square metre, the atmospheric pressure on evacuated flat glazing is immense. And for evacuated glazing, the same applies as for vacuum panels: only a lasting vacuum guarantees good thermal insulation. Now, this research project is to provide evidence that evacuated glazings with special functional layers are technically feasible for architecture.
