| Popis: | Dissertation, Rheinisch-Westfälische Technische Hochschule Aachen, 2023; Aachen : RWTH Aachen University 1 Online-Ressource : Illustrationen, Diagramme (2023). = Dissertation, Rheinisch-Westfälische Technische Hochschule Aachen, 2023 With the Climate Protection Act, the German government has set the goal of greenhouse gas neutrality by 2045. To achieve this, new buildings should already be supplied mainly independently of fossil fuels, as they will otherwise be renovation cases within the next 20 years. Renewable energies play an important role in achieving this goal. A good way to make renewable energies usable without much additional effort is to give already existing components of the building additional functions. Here, for example, the façade or the roof can be solarthermally activated or supplemented with photovoltaic modules. Deep foundations can also be given a geothermal function to absorb or release heat in addition to their static function. In addition to generation, integration into building components is also an option for the transfer of heat or cold in the building. Here, for example, the ceiling can be activated by radiation panels. As a contribution to reducing the consumption of non-renewable energies in the building sector, this thesis deals with component-activated solutions made of steel for plus-energy buildings in lightweight metal construction; the term "component-activated" is defined more broadly than in the thermal activation of concrete ceilings. A system for the thermal activation of steel trapezoidal profiles at the ceiling is explained, which can supply heat or dissipate it if required. Furthermore, a solution is presented to activate the rear-ventilated steel façade (VHF) by solar thermal means. In addition, the use of organic photovoltaic modules (OPV) on VHF and on steel sandwich panels will be investigated. Furthermore, two possibilities for geothermal activation of deep foundations using steel energy piles are shown. The described systems are analysed numerically and examined by measurements using demonstrators. With the help of thermal building simulations on a sample building and a pre-dimensioning approach, dimensioning variables are determined and the required areas for a photovoltaic system are derived in order to achieve a plus-energy building.
