Demonstrate significant cost reduction for Building Integrated PV (BIPV) solutions Support will be given to solutions that address: a) new BIPV product concepts to meet these requirements and cost-efficient production techniques reducing their additional cost by 75% by 2030 compared to 2015 levels ([[https://setis.ec.europa.eu/system/files/integrated_set-plan/declaration_of_intent_pv.pdf]]Annex I. BIPV detailed targets) and; b) demonstration of these concepts into a BIPV energy system that guarantees the building functionalities and energy needs on a life-cycle basis. Proposals will involve multidisciplinary consortia including the PV manufacturing industry. The building materials industry, certification bodies and market actors who are committed to adopting/implementing the results will also be included where relevant. Proposals will also address standardization issues.Proposals are expected to bring the technology from TRL 5-6 to 6-7 (please see part G of the General Annexes).The Commission considers that proposals requesting a contribution from the EU of between EUR 6 to 10 million would allow this challenge to be addressed appropriately. Nonetheless, this does not preclude submission and selection of proposals requesting other amounts. BIPV need to satisfy multiple building functions such as mechanical rigidity and structural integrity; primary weather impact protection including rain, snow, wind, etc.; energy economy, such as shading, daylighting, thermal insulation; fire protection, noise protection, in addition to architectural and aesthetic considerations, so as to replace roofs, facades and shading devices. At the same time, a control system for building management functions, grid-feeding, self-consumption and local storage needs to be considered. The project is expected to contribute to the implementation of policies towards Zero-Energy Buildings. By achieving a substantial reduction of the BIPV costs which would trigger the penetration of BIPV in the building sector, they are also expected to contribute to the creation of new opportunities and the diversification of the European PV manufacturing industry.
