TP: Development paths and optimization potentials
Project content
Analysis and optimization of solar energy supply systems for single and multi-family houses in new buildings whose heat and electricity requirements are predominantly provided by solar energy.
Well over half of final energy consumption in Germany is used in the building sector. However, the resources required for this can also be generated in the building itself. The decisive factor here is how the building as a producer of energy is arranged with the higher-level infrastructures, primarily the electricity grid. In supply concepts currently implemented on the market, solutions for electricity and heat are generally considered separately. Electricity-based supply components in particular hardly interact with the thermal or even solar potential available in the building.
In the SolSys project, solar energy-based supply systems for residential buildings are analyzed from an integral viewpoint of electricity and heat and examined for their future viability.
In a first step, relevant, market-available systems from the areas of electricity and heat supply are structured in a research work in a technology matrix in order to be able to derive relevant future technology options on this basis. The processes and paths activated for financing and implementation are systematically recorded and analyzed with regard to inconsistencies and obstacles. Furthermore, six residential buildings (four single-family homes and two apartment buildings) will be subjected to intensive monitoring for these analyses. Based on the simulation models and the systems structured in the technology matrix, reference systems are derived with which a comprehensive sensitivity analysis and parameter study is carried out. The simulated systems and their results are presented using the technical-energetic, economic, ecological and sociological evaluation criteria and parameters developed. The results obtained will be incorporated into a planning guide as well as into concept modules for the online encyclopaedia Wikipedia.
