The high energy consuming building sector needs to meet both electricity and heat demands. In a nearly zero energy building (NZEB) scenario most of the consumed energy would be generated locally by means of renewable solutions that nowadays seem not to provide an attractive cost-competitiveness. Solar based technologies tend to be the most promising ones, but for high densely populated and restricted areas buildings thermal loads are a major setback concerning zero energy performance. Traditional fossil fuel or single renewable approaches will not be valid from efficiency and/or cost competitiveness. Photovoltaics (PV) seem to have a great future as the build environment local generation technology, but high capacity scenarios related grid impact is still a serious threat for massive deployment. Heat pumps (HP) are an efficient approach towards a reduction of building thermal comfort related CO2 emission and capable of using the electrical infrastructure as back-up source. Therefore, if both technologies are individually suitable for electricity and heat generation, merging them in a unique solution should enable even higher benefits. The work is focused on the analysis of the potential use of PV and the smart combination with HP towards entire-lifetime feasible solutions for zero energy buildings. The techno-economic analysis is focused on an 80s residential-use 95-dwelling building, located at 6 different EU sites for a set of 5 scenarios, combining market standard natural gas boilers, conventional heat pumps and PV systems. The current results continuing the analysis in [1] are focused on the performance KPIs of the proposed smart PV & HP system, showing that the solution could be a currently efficient, renewable and cost-competitive approach towards NZEB.
