26 CONCLUSIONS La introducció d energies renovables en el sistema de poligeneració de Parc de l Alba en el servei de subministrament de calor i fred es viable tècnica y econòmicament. Les solucions estudiades han estat: Biogàs Biomassa amb solar de concentració i màquines d absorció (SCBC) Geotèrmica i fotovoltaica (GSHP) El sistema biomassa+solar concentració (SCBC) presenta un 13 % d estalvi d energia primària% i un VAN un 53 % millor, respecte al cas geotèrmia+fv (GSHP). Les emissions de CO 2 son un 18 % superiors en el cas SCBC que en el GSHP.

27 Agraïments Present study has been developed in the framework of SMARTREFLEX Project (Smart and Flexible 100% Renewable District Heating and Cooling Systems for European Cities) co-funded by the Intelligent Energy Europe Programme of the European Union by means of Grant Agreement number IEE/13/434/SI As a consequence, software energypro, which is sponsored by EMD International A/S for SMARTREFLEX, has been used to develop energy calculations. Institut Català del Sòl (INCASOL) de la Generalitat de Catalunya is also partner of Smartreflex and has contributed providing urban planing data of both case studies. Consorci Urbanístic del Centre Direccional de Cerdanyola del Vallès (Parc de l Alba) and ST4 Plant in Parc de l Alba from Grupo San José have contributed providing data about real performance and future development planning of district heating and cooling system in Parc de l Alba. Parc de l Alba_Barcelona Synchroton Park is a public consortium between the City Council of Cerdanyola del Vallès and the Catalan Land Institute (INCASÒL). Saad Saleem saadsaleem2005@gmail.com student of KIC RENE Programe has developed his Master Thesis based on Case Study of Parc de l Alba in the framework of Smartreflex. Results of his work has been used to write this article. For further information contact Laura Sisó, Senior Researcher at IREC lsiso@irec.cat
