Energie Campus Nürnberg – BUILDING II

The BUILDING research field at the Energie Campus Nürnberg conducts research into issues concerning the energy efficiency of buildings of the future. This project sees Nuremberg Institute of Technology, the Fraunhofer Institute for Building Physics, and the University of Erlangen-Nuremberg working together in close cooperation.
Energy-efficient materials/renovation of old buildings

In the average private household, heating accounts for over 75% of the building’s total energy demand, and for non-residential buildings this percentage is even higher. With energy prices rising, the most significant factor in saving primary energy for heating is to equip buildings with highly insulating materials and insulation systems. While highly insulating wall building materials can be used from the outset in the new-build sector, e.g. for zero-energy or energy-plus houses, there is now an urgent need for thermal renovation in the much larger stock of old buildings (which account for 90% of buildings). For this, the rate of renovation must be doubled from the current 1% to 2%. The research work planned for this makes a critical contribution to achieving this objective.
There are three main areas of research:

1: Developing new highly insulating building and insulation materials

2: Developing intelligent materials as components of building and insulation materials

3: Developing new components for energy-plus houses (Aktivhaus)

EnCN 2015 research report

The BUILDING II research field studies energy efficiency in buildings with a focus on the building structure and the supply systems in the building.

In the “Energy-efficient materials/renovation of old buildings” sub-project, researchers are working to develop thermally optimized building and insulation materials and equip them with intelligent properties. The activities are not only looking into solid wall construction materials, but also highly insulating mortar products and thermal insulation plasters, as well as the integration of these materials into an energy-efficient wall system.
