For future buildings (nZEBs according to EPBD) efficient and cost-effective heating systems with a high share of renewable energy ar0e1 r1equired. Heat pumps (HP) are considered as one of the key technologies in the building sector. However, in particular in high-density housing areas, source exploitation is strongly limited. Accordingly, the market in Austria does not currently provide real alternatives to apartment gas or electric boilers. Split type HPs with low power can be made compact and cost effective and thus offer new possibilities. However, split type HPs represent a real alternative only if the acceptance for them can be improved by means of improved modularity, design, architectural attractive integration in the building envelope and reduced sound emissions. The goal of the Austrian FFG research project FitNeS is the development and optimization of modular split HPs with compact and silent façade-integrated outdoor units. The outstanding features of the concept are a modular design with a high degree of prefabrication and representing a visually and architectonically attractive, economic and sustainable solution for both new constructions and renovations. Different concepts of façade-integrated outdoor units will be developed and evaluated with regard to design, façade construction, accessibility (for maintenance), building physics, efficiency, etc. on the basis of the technical and non-technical boundary conditions.
