The panels presented as test cases at the project meeting at the TU Dresden, alongside installed systems from other European "climate locations", demonstrate the efficiency and the already successful cooperation between the international and interdisciplinary partners.
The energy consumption of buildings depends on the thermally insulating building materials used and is also heavily dependent on the climate and local weather conditions. In the interdisciplinary EU research project iClimaBuilt (EU Framework Programme Horizon 2020), which has been running since March 2021, the sustainable solutions developed for building envelopes are therefore being investigated in long-term tests under real operating conditions at five so-called "climate sites". One site is the so-called CUBE at TU Dresden, which representatives of the 27 project partners from 14 European countries were able to visit during the mid-term project meeting (see photo 1). In May 2023, three of the innovative external wall systems developed in the project will be installed here as test panels for further investigations. One of these systems was developed and produced in cooperation between HTWK, TU Dresden, RI.SE and TU Hamburg. This lightweight sandwich consists of thin-walled high-performance concrete (HTWK Leipzig) with carbon reinforcement systems made from renewable raw materials such as lignin (TU Dresden) and ultra-light aerated concrete as a thermal insulation core (RI.SE) using aerogels to improve the insulating properties (TU Hamburg).
A visit to the industrial production line for carbon concrete components in the Carbon Concrete Technology Centre at HTWK Leipzig was therefore an additional item on the meeting programme (see photo 2).
The parallel development of the individual materials and production technologies in iClimaBuilt is both a challenge and an inspiration. It testifies to the complexity of the construction industry, especially in the link with research. The panels presented in Dresden as test cases, as well as the systems installed at other "climate locations" in Europe, testify to the efficiency and the already successful cooperation between the international and interdisciplinary partners.
