The built environment remains a strategic research and innovation domain in view of a full decarbonization of our economy. As set in the European Green Deal, one of the two pillars of this transition towards decarbon-ization is the on-site production of electricity via sustainable , renewable energy technologies, covering buildings' energy needs but also providing services to the grid. The exploitation of building skin surfaces represents a huge potential in turning the built environment into a decentralized renewable energy producer, by saving lands and landscape areas, as well as advancing towards a refurbished and improved building stock in the EU. Today, BIPV has achieved a high level of technical maturity and the market perspective looks promising. Supported by increasing technological developments, by digitization and process innovations, such systems are ready to explore the next frontier: to be fully integrated in the construction market and to help make cities healthier and powered by on-site solar renewables. Building integrated photovoltaics (BIPV) also offers a key opportunity for PV market development and the establishment of a competitive value chain in Europe. Existing BIPV products offer to architects, building owners, façade makers and real estate developers a diversified range of products which can be manufactured and customized like any conventional building envelope solution. However, the BIPV market has not reached relevant development and continues to occupy a niche of both PV and building markets. In addition, the combination of building and solar industry processes requires the involvement of several stakeholders that have to be carefully coordinated, which remains challenging in such a multidisciplinary field. Its hybrid nature, methods and logics, if not streamlined and optimized within a virtuous cycle in the supply chain, could lead to a fragmentation of the sector. This could discourage many building investors, planners or industries from investing in solar buildings or, in any case, generate a "fear of surcharge", which would eventually compromise decision making. Even though the most evident BIPV barriers are clear and many issues have been solved during the last years, one of the main challenge today is to widely demonstrate BIPV in real buildings with a turnkey solution and an efficient process able to ensure performance, reliability, durability and replica-bility in a cost competitive way. The BIPV Status Report 2020 aims to provide a practical handbook to all stakeholders of the BIPV development process, providing insights to each of these actors, although they approach the topic of BIPV from different perspectives. This handbook highlights the main steps of BIPV's evolution, the key challenges of the sector, as well as the necessary interdisciplinary of the activities across the whole BIPV project development process. The status of BIPV in Europe, relying on an extensive database of BIPV case studies and on an analysis of past and future market trends, is presented over the critical reflection on the main traits of its evolution along last decades. The case studies analysed, the database of products and the results from our applied research fully oriented to practice and to the real market, offer to architects inputs for new projects and references to quantify BIPV costs and advantages. This can eventually help them to reach new customers. Moreover, the practicality of this booklet and its info-graphics make it a potential tool for public authorities and educational istitutions to promote BIPV and, in general, the sustainability of buildings. The economic calculation and the cost competitiveness analysis can support investors, building managers and real estate developers in taking the most economically convenient decisions. The crucial question of cost competitiveness is illustrated with data coming from the real market and built examples and is representative of the common EU building typologies and building envelope solutions.
