Demonstration sites

On summer 2015 two small-scale demonstrators have been realized and installed on the roof over the research center of Tegola Canadese headquarters, in Vittorio Veneto (Italy). The roof it’s usually used as a testing center, in which several products of TEGOLA production and R&D have been installed to analyse behaviour of the building components with ageing.This roof is a challenging demosite to analyse photovoltaics, since it is a south east exposed roof, with 18% of slope. The test roof consist in two separate stands of BiPV products, parallel installed by torch on the roof. No retroventilation have been provided to BiPV, that have been installed in direct contact with the rear bituminous waterproofing substrate. The roof covered with BiPV is a concrete roof, that have been covered with 3 layers of  membrane (2 old layers, one the brand new installed on purpose for this demo site).

Goal of this activity is to demonstrate the  BIPV solar shingle conceived for an easy-mounting and on-site customization. It consists of a durable glazed panel (containing crystalline solar cells provided by the partner Meyer Burger) integrated in a waterproofing back-sheet layer made of a bitumen-based membrane. Two different outdoor test-facilities have been installed, both in Vittorio Veneto (Italy) and in Lugano (Switzerland), in order to gain experience from installation in different conditions, nailing on a wood structure (Lugano) rather than torching on on a waterproofing membrane (Vittorio Veneto). Those procedures are both forecasted in the Athens big scale roof demosites. Collection of output data on the prototype electrical efficiency, measured in real conditions, allows comparing the behavior of the solar shingle with existing products on the market, installed in the same conditions, as a comparison benchmark.

A mobile façade mock-up prepared by the coordinator of the project Züblin AG has been presented on the 04th of November 2015 during the 10th Energy Forum on Advanced Building Skins in Bern, Switzerland. The mockup demonstrates, in real-scale, BIPV façade systems and innovative BIPV technologies developed in the project. The mockup, originated by the collaboration of Züblin with the architecture office UN Studio, Fraunhofer ISE and the manufacturer Meyer Burger, demonstrates variants and possibilities in terms of architectural and technological design/manufacturing of  BIPV systems for the building skin. The mockup will be exhibited around Europe in next years so that it will become a mobile demonstrative facility for  project dissemination:

  • 03rd-04th November 2015, Energy Forum on Advanced Building Skin, Bern, Switzerland
  • 23rd November 2015, STRABAG iNNOVATIONSTAG
  • since 25th January 2016, Züblin-Campus Stuttgart, Germany
  • 20th-23th September 2016, GlassTec, Düsseldorf, Germany
  • 16th-21st January 2017, BAU 2017, Munich, Germany
  • Since February 2017, SUPSI-Campus, Lugano, Switzerland

On summer 2015 two small scale demonstrators have been installed at the SUPSI Campus. The stands consist in two small structures for installing BIPV solar systems on roof surfaces (1,8 x 3,0 m). Real building layerings including substructures, supporting layers, thermal insulation, and ventilation air gap will be built onto the load-bearing metal structure of the stands in order to simulate the real building envelope both in terms of constructive/architectural and technological aspects. The stands will be aimed to demonstrate the Construct PV technology (visits, professional development and student’s training, etc.) as well as to monitor the performance of the BIPV roof system developed in the project (stand 1) in comparison to BIPV systems already existing in the market (stand 2). Energy production (performance ratio, temperature of modules, etc.) and building performances (watertightness, temperatures, ventilation, etc.) will be analysed.
