Summary
Structure of the AktivDHKS system solution
The overarching goal of the research project is the sustainable and economical refurbishment of existing buildings under the premise of emission-free and regenerative heat supply. The increase in the refurbishment rate in Germany is to be implemented with a newly developed, reversible, scalable and flexibly applicable active insulation heating and cooling system (AktivDHKS), focusing on a widely applicable, affordable refurbishment solution with high marketing potential and expected minimal CO2 avoidance costs. This should enable a large part of the German building stock to be refurbished more quickly, cheaply and sustainably.
The refurbishment of existing buildings must be implemented efficiently, cost-effectively and in a climate-neutral manner in order to achieve independence from fossil fuels of any kind as quickly as possible. AktivDHKS uses the energy generated on site from renewable sources (geothermal energy, photovoltaics) and the existing surfaces and storage masses of the buildings to enable an affordable, comprehensive, permanent and stable supply of electricity, heating and cooling from renewable sources. In the view of the applicants, the use of building envelope surfaces for energy generation and storage is a necessary solution to the problems of the energy transition.
In order to achieve the climate protection targets in the building sector, the energy-efficient refurbishment of buildings must be considered further together with the renewable energy supply. The geothermal use of the ground - both as a source of heating and cooling and as seasonal energy storage - as well as the massive expansion of locally generated PV electricity are of great importance for the heating transition. Tried and tested regenerative heat supply concepts must be transferred from new buildings to existing ones. Decentralized supply concepts should be implemented from the periphery towards the city centers. The intelligent coupling of heat and electricity as well as the utilization of the thermal storage capacity of buildings offer great advantages for making the use of self-generated electricity more flexible and thus for the economic operation of buildings.
