System analysis of the technical and economic potential of solar energy for a 50 and 100 % renewable energy supply for buildings and urban districts in the annual balance.

Goals
There is a wide range of renewable energy systems to equip homes for the future. Solar thermal collectors can be used to generate heat and a photovoltaic system can be used to generate electricity. In combination with a heat pump, photovoltaics can also be used to generate heat. There are also other concepts and ideas for supplying buildings with renewable energy.
The Institute of Building and Solar Technology (IGS) at TU Braunschweig, together with the Institute of Thermodynamics and Thermal Engineering (ITW) at the University of Stuttgart and various industrial partners, will carry out a comprehensive system analysis in the future:solar project, which will be used to identify promising overall systems. The aim is to determine the technical and economic potential of solar energy for a regenerative share of 50 and 100 percent in the energy supply of single-family homes, apartment buildings and urban districts. This potential is also to be investigated for existing buildings. The cost-benefit ratio of building refurbishment and technical equipment will be evaluated.
The selected balance includes both the energy requirement for building operation in accordance with the applicable Energy Saving Ordinance and the electricity requirement for use and equipment. Therefore, in addition to solar thermal energy and photovoltaics, other renewable energies and sustainable technologies for heat, electricity and cooling generation are taken into account.
