“…Such a system can be completely integrated in the façade and thus minimizes the space required for renovation inside the flat. In addition, electricity required by the system can be potentially covered by a photovoltaic (PV) system installed on the roof or on the façade of the flat [2]. Compactness, versatility and high potential of selfsufficiency make this system ideal for renovation of low energy demand multi-family buildings.…”

A new compact and cost effective heating and ventilation concept for decentral renovation of small flats in multifamily houses was developed and investigated in the framework of the Austrian project “SaLüH!” through a dynamic building and HVAC simulation study based on results of laboratory measurements of functional models. The system consists of a façade integrated supply air/exhaust air heat pump equipped with a desuperheater allowing to increase the heating power and to add more freedom to control the system. The simulation results show that such a system is able to improve the thermal comfort of the flat (compared to the standard heating concept without desuperheater) with good indoor air quality and satisfying energy performance. The proposed system - because of its versatility and compactness - represents an ideal solution for decentral renovation of flats in multi-family houses, especially in case of limited space inside the flat and if central solutions are not possible for technical, economic or social reasons.
