Assessment and mapping of potential interferences to the installation of NSGE systems in the Alpine Regions Assessment and mapping of potential interferences to the installation of NSGE systems in the Alpine Regions Deliverable D.4.1.1 – Assessment and mapping of potential interferences to the installation of NSGE systems in the Alpine Regions 16/12/2015 – 07/09/2018: A large-scale web GIS map of possible underground interferences with Near-Surface Geothermal Energy systems will be published online, together with a reference guide explaining how the input data were collected, homogenized and processed. Version: Revision 02, 04 September 2018 This document was written in the framework of the ERDF funded project GRETA (16/12/2015 – 14/12/2018). It is the first deliverable of the Work Package 4 (or WPT3 according to the EmS numbering of WPs) “Assessment and mapping of the potential of Near-Surface Geothermal Energy (NSGE)”. The Politecnico di Torino (POLITO), as responsible partner of WP4, developed this report with contribution of the following project partners: TUM, EURAC, ARPA Valle d’Aosta, GeoZS, BRGM, GBA, University of Basel, and Regione Lombardia. This deliverable deals with the large-scale mapping of geological features and other factors (environmental issues, bans, law restrictions, etc.) which may interfere with the installation of Borehole Heat Exchangers and/or water wells for Ground Water Heat Pumps. For this assessment, the involved partners collected and processed geo-referenced data of such features, which were put together in a Web GIS available on line. Also, partners provided sources for other kinds of data (books, articles, papers, web-viewer, pdf maps etc.) which are not in GIS formats. This report therefore serves as a reference guide of the Web GIS and as a complementary source of information about risks, interferences, issues and possible solutions for installers, designers, and public authorities involved in the design, approval and installation of NSGE systems. GRETA is co-financed by the European Regional Development Fund through the Interreg Alpine Space programme.
