Le projet de recherche ACTIVE INTERFACES portent sur les stratégies opérationnelles permettant de dépasser les obstacles à l'intégration à grande échelle du photovoltaïque intégré au bâtiment (BIPV) dans les processus de renouvellement urbain. Il vise à apporter une contribution significative à la nouvelle "Stratégie énergétique 2050", qui implique l'implémentation en Suisse de 10 GW d'énergie d'origine photovoltaïque. Malgré les progrès technologiques et l'évolution économique, seule une modeste partie du BIPV est actuellement valorisée dans le tissu urbain. ACTIVE INTERFACES permettra non seulement de décortiquer et d'identifier les barrières actuelles, mais proposera également des alternatives opérationnelles concrètes, ainsi qu'un lien plus direct entre les développements industriels les plus avancés et les connaissances opérationnelles en matière de design architectural et de processus de construction.
Lay summary

Le projet de recherche interdisciplinaire ACTIVE INTERFACES portent sur les stratégies opérationnelles permettant de dépasser les obstacles à l'intégration à grande échelle du photovoltaïque intégré au bâtiment (BIPV) dans les processus de renouvellement urbain. Par son approche holistique - de la production industrielle jusqu'à l'implémentation locale - il vise à apporter une contribution significative à la nouvelle "Stratégie énergétique 2050", qui implique l'implémentation en Suisse de 10 GW d'énergie d'origine photovoltaïque. Malgré les progrès technologiques (augmentation continue de l'efficacité) et l'évolution économique (réduction des coûts), seule une modeste partie du BIPV est actuellement valorisée dans le tissu urbain. Il existe en effet divers types d'obstacles qui ont empêché jusqu'à présent l'émergence d'une réelle chaîne de valeurs dans ce domaine pourtant stratégique. ACTIVE INTERFACES permettra non seulement de décortiquer ces barrières de manière détaillée, mais proposera également des alternatives opérationnelles concrètes. Par la création d'une matrice de situations archétypiques et par la réalisation d'une série d'études de cas en sites réels, le projet offrira notamment un lien plus direct entre les développements industriels les plus avancés et les connaissances opérationnelles en matière de design architectural et de processus de construction. Il facilitera ainsi l'émergence quantitative et qualitative d'une source locale d'électricité, qui contribuera durablement au virage énergétique, s'intégrera directement à l'environnement construit et sera ainsi bien acceptée au plan socioculturel.

Abstract

The ambition of the present research project is to bring a relevant contribution to the new "Energy Strategy 2050". To reach the energy vision of the Confederation, 10 GW of PV is required. In that perspective, through a holistic approach - from industrial production to local implementation - the project will bring a decisive strategic contribution to cross over the current obstacles for a large-scale advanced PV integration into urban renewal processes.In spite of technological progress (continuous increase of efficiency) and economic evolution (reduction of costs), only a small part of the solar electricity potential of building-integrated photovoltaics (BIPV) is currently valorized in urban areas (integration into façades or roofs elements). Indeed, diverse types of obstacles exist and have until now limited the large-scale implementation of BIPV into urban renewal processes, as well as prevented the emergence of a real chain of added values in that strategic domain. By studying those barriers and proposing alternative urban and architectural solutions based on a holistic approach, this project goes further and has a wider scope than the technological progress achieved so far.Working on the urban renewal processes (renovation, transformation or substitution of existing building) contributes to reduce end energy consumption, promote the use of renewable energy and cut CO2 emissions. BIPV contributes also directly to offset the loss in electricity production from nuclear energy. The approach will study in a structured and in-depth manner the technological and economic parameters related to the production, but also to construction constraints, law conditions, architectural quality and socio-cultural issues. In a sustainability perspective, the development of new adapted solutions will take into account diverse criteria (energy, comfort, LCA, costs, esthetics, costs of electricity and grid connection). By assuring the integration of applications-tests carried out on representative sites, this project will indeed offer an attractive link between the development of industrial elements and the generation of operational knowledge directly integrated into new adapted solutions and design strategies (interesting potential in terms of transferability).The final objective of the interdisciplinary project ACTIVE INTERFACES is so to generate from the built environment a sustainable low-cost and accepted (or even desired) source of local electricity, making the vision of over 10 GW of solar electricity in Switzerland significantly easier to implement. Developed with this aim in mind, the research project will not only produce decisive operational outputs, but also give a precise prioritization of the efforts. The project will thus bring the Swiss PV scientific community to an internationally unprecedented competitive position.
