| Popis: | 35th European Photovoltaic Solar Energy Conference and Exhibition; 1848-1854 The high energy consuming building sector needs to meet both electricity and heat demands. In a NZEB scenario most of the consumed energy would be generated locally by means of RES 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 still a major setback concerning zero energy performance. Traditional fossil fuel or single renewable approaches will not be valid from efficiency and/or cost competitiveness. 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. HPs are an efficient approach for 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, merging them in a unique solution should enable even higher benefits. The current work is focused on the potential analysis of PV and smart combination with HP as entire-lifetime feasible solutions for NZEB. 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 HPs and PV systems. The results show that the proposed solution could be a currently efficient, renewable and cost-competitive. |
