Analysis of the Technological Innovation System for BIPV in Spain 2022
- 2022
-
Reports (other academic/artistic)abstract
- This report analyses the Technological Innovation System (TIS) of the Building Integrated Photovoltaic (BIPV) technology in Spain as it was in March 2022; the analysis aims to facilitate and support the implementation of BIPV and the innovation and industrial BIPV solutions development. It starts by identifying the actors, networks, and institutions to perform the structural analysis. Then, the functional analysis includes a review of the BIPV-related publications, projects, and patents. Interviews with relevant experts in the field and tailored surveys addressing each stakeholder group have completed the experimental basis for the eight defined TIS functions assessment. Results show that BIPV knowledge development in Spain has sufficient quality, although it is mainly limited to the scientific and academic fields; the innovation system needs further technological and market knowledge, more in BIPV roofing than in BIPV façade solutions. Also knowledge dissemination is weak, especially between the photovoltaic and the construction sectors. Entrepreneurial experimentation, also identified in the construction sector, is slowly increasing, and more companies’ competency is needed. When it comes to resources, there are funds for PV research, development, and innovation projects, but aids are not specific to BIPV. Besides, there is a lack of BIPV-qualified technicians; BIPV is directly competing with building added photovoltaics (BAPV), usually with lesser costs and faster growth due to the PV selfconsumption’s success. About the development of social capital, smooth communication and trust are essentially limited to just the known agents, so some initiatives are necessary to improve this market driver. Concerning legitimation, there is good acceptance and perception of BIPV from architects and general society; however, two main barriers increase the customers’ resistance to including BIPV: costs and lack of related regulations. Two major difficulties are that BIPV is not explicitly in the Technical Building Code, and there are no specific financial incentives or subsidies for BIPV. The BIPV market in Spain is still a niche market, slowly growing and with good future perception. The search guidance is not clear but starts from a general framework that, despite all, could be favourable to BIPV development; BIPV can benefit from the support addressed to PV self-consumption and buildings’ energy retrofit projects. To further develop BIPV towards a commercial market, it is recommended to include BIPV in building codes and get in place BIPV-specific incentives. Other suggestions to boost BIPV in Spain are at the end of the report. The annexes contain lists of BIPV projects, patents, publications, and relevant stakeholders.

Coloured BIPV : Market, Research and Development
- 2019
-
Reports (other academic/artistic)abstract
- In the building sector, net-zero energy performance targets and reduction of CO2 emissions are the main drivers for building integrated photovoltaics. Recent market studies [10,18,19] show the history and perspective of the global market in the BIPV sector and calculate a global compound annual growth rate of ~ 40 % from 2009 up to 2020.In Europe, the BIPV market is in a transition. The past decades of a slowly emerging BIPV market have been characterized by the original dominant value of BIPV: a building that communicates an image of sustainability and innovation. Payback time or "return on investment" have not been the major parameters in the decision process for applying BIPV. This is changing now. In most European countries, the new regulations on energy performance in buildings (derived from the European Energy Performance of Buildings Directive and the Directive on energy efficiency) have been translated in national regulations/laws, stating that all new (and freshly refurbished) buildings of the EU member states should be nearly zero energy buildings (nZEBs) by 2020. Thus, the time for the regulations to become mandatory is very near. It is expected that the energy performance regulations are now taking over as the main driving factor for the BIPV market and that should have huge consequences in removing the difference between a conventional building component and a BIPV component both in aesthetical and construction terms. This has led to intensified research and development aiming to create BIPV products that come in a variety of colours and sizes, while at the same time being as close as possible to existing building components, to its requirements and how it is considered by the construction industry.The given market overview of state-of-the-art coloured BIPV products clearly reveals that for all parts of a BIPV module (glass, polymers, PV-active layers), there are technical solutions available for colouring. Pilot projects utilizing coloured BIPV products have been built in numerous (mainly European) cities clearly demonstrating the maturity of these solutions.The key aspect that has been slowing down the progress of implementation of these aesthetically appealing and technically sophisticated new products into a wider market are the costs. In this respect, a lot of effort has been made to improve and optimize the relationship between colour and efficiency/power generation of BIPV elements. The results of the past and on-going innovative research and intensified fundamental considerations are also summarized in this report.Besides the colour perception of the coloured BIPV elements under solar irradiation which is essential for the acceptance of the exterior appearance of a building, also transparency and inside visual comfort of BIPV – windows and façade elements are essential for the users and inhabitants.
