New opportunities with new technologies
Energy-optimised buildings are already technically realisable today. But also in the building trade, new technologies offer new opportunities. New materials, technologies and systems for construction engineering and for buildings' technical equipment can make buildings more comfortable, slimmer, more energy-efficient, more flexible, more convenient, more cost-efficient, or more durable. Here, on an ongoing basis, we present new technological approaches arising from research into "buildings of the future", show the pilot projects in which prototype systems are already proving themselves, and show which hurdles must yet be surmounted before market entry is possible.
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.

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.

Construction systems with integrated phase-change materials (PCM) can store a high degree of heat at room temperature. If this heat is transported by means of water-carrying systems, it is possible to regulate room temperatures in an energy-efficient manner. This research project focused on the ongoing development of materials, components and systems with paraffins, the identification of promising applications, the performance of system tests and the development of a planning tool.

Even slight temperature differences can be used for heating or cooling buildings. This involves spatial and temporal temperature potentials. The temperature differences between different areas of a building can be used for heat transfer between rooms which are too warm and rooms which are too cool, so that thermal homogenisation of the building structure can be achieved, even if there are differences in room usage and heat loads.

Sandwich building elements allow a wide variety of material combinations, and have versatile implementation possibilities in the building trade. In this research project, sandwich building elements with integrated vacuum insulation were developed. They are now being tested and scientifically evaluated in practice in a demonstration building in Neumarkt in der Oberpfalz (Germany).
