StaGiMo research project to standardise the integration of compliant BIPV carriers and substrate layers

Reference case: StaGiMo research project to standardise the integration of compliant BIPV carriers and substrate layers

After EU law (judgment C-100/13 ECJ) made it possible to use alternative materials as an intermediate layer for BIPV carriers and substrate layers, installers began to use materials other than the previously common polyvinyl butyral (PVB). This resulted in some challenges as the properties of the building products changed due to the new materials.

These building products require approval in individual cases (ZiE) or general design approval (aBg) and have to meet requirements for electrical safety and fire protection among others. The StaGiMo research project aims to develop a standardized procedure.

The acronym StaGiMo stands for "Standardisierte Gebäudeintegrierte Photovoltaik (GIPV) Modulanwendung in Dach und Fassade", which can be translated as “Standardized Building integrated photovoltaics (BIPV) for module application in roofs and facades”.

Considering functional safety, BIPV makes most sense in ventilated structures. The research project therefore focuses on the application in ventilated curtain facades (vhF) and in-roof systems.

Involved regulations/ standardsThe standards to which we test include but are not limited to:
EN 50583Photovoltaics in buildings part 1: BIPV Modules
EN 50583-2Photovoltaics in buildings part 2: BIPV Systems
EN 15601Hygrothermal performance of buildings
EN 14449Glass in building laminated glass/safety glass
IEC 61730Photovoltaic module safety qualification
IEC 61215-seriesTerrestrial PV modules - design qualification and type approval
MCS 017Product Certification Scheme Requirements: Bespoke Building Integrated Photovoltaic Products

The aim of the project is to develop a standardized integration of BIPV carrier and substrate layers in order to shorten the planning and construction time and thus reduce costs. To achieve this, the team is going to develop technical rules and appropriate test procedures that provide clear guidance on how to comply with electrical and fire safety requirements. This should make it easier to obtain general construction type approval in the future. Ultimately, the expansion of GIPV as an important component of the energy transition should be accelerated.
