Model-based Design of a Solar Driven Hybrid System for Space Heating and DHW Preparation of a Multifamily House

Following the most recent European Directives on Energy Performance of Buildings and Energy Efficiency, new solutions for DHW production, space heating and cooling have to be developed and applied to reduce the primary energy consumption of residential buildings. Due to the complexity of installation and control, H&C hybrid systems exploiting a mix of conventional fuels and RES are not yet widespread although they can bring important savings to the yearly building energy consumptions. This work summarizes the parametric analysis used as part of the design process of a hybrid system for the retrofit of a multifamily house located in Madrid, and shows how heating, cooling and DHW demands of multifamily houses can be covered by a heat pump plus solar systems, integrating a high share of RES. The design of the system has taken into account energy savings, economics and architectural aspects.
