Architectural Photovoltaic Applications: Lessons Learnt and Perceptions from Architects

Abstract

Researchers have reported that despite technological development in photovoltaic technology and substantial cost reduction, there is still a narrow interest in architectural photovoltaic applications (APA). Lack of interest is correlated to various bottlenecks, and one of them is a lack of knowledge among architects on the possibilities and approaches to adopt APA. In response to the issues mentioned, the aim of the research presented was collecting qualitative and quantitative information from architects as lessons learned and perceptions in regards to APA. In total, 30 architects with and without experience of using photovoltaics (PV) were invited and interviewed. They were asked about their experience, design and decision-making process with PV, their understanding of integration, and the decisive factors to use APA. The results showed apparent differences between the experiences and perceptions, and they highlighted the lessons learned from realized projects. The analysis of the visual implication of PV integration shows that, to the eyes of architects, integration of PV into architecture does not depend on the PV product used, but instead, that when PV is part of the design concept and design process, the outcome is seen as a meaningful integration.

Luminescent solar concentrators for building integrated photovoltaics: opportunities and challenges

“…73 Currently, there appears to be no data for a BIPV learning curve, and if every building is different how do BIPV technologies escape from being confined to demonstration projects? From a recent survey of architects, while aesthetics was the most important consideration overall, several interviewees indicated that transparency and/or colour was only desired as long as no sacrifice in technical performance had to be made 136 – a tough ask!…”

Mandatory Policy, Innovations and the Renewable Energy Debate: A Case Study on Building Integrated Photovoltaics

“…There are significant benefits associated with the adoption of BIPV and these suggest a supportive perspective that it should be promoted by policies in view of the environmental need already highlighted in the Introduction. Stakeholders believe that BIPV provides one of the best methods for on-site energy generation while promoting green building strategies [44]. In the literature, there are about four classes of added benefits related to the use of BIPV as an energy source or as a building material, such as its design, economic, social and environmental advantages.…”

“…In general, the absence of standards backed by policy tends to make the adoption process more complicated [63]. This impacts the processes of approval, design, fire safety and product development [44,63].…”

Building Integrated Photovoltaics (BIPV): Analysis of the Technological Transfer Process and Innovation Dynamics in the Swiss Building Sector

“…By reviewing parameters and strategies for customizing BIPV systems, the paper addresses barriers to adoption, emphasizing the importance of enhancing both energy generation and aesthetics. Finally, [15] investigates architects' perceptions and experiences with architectural photovoltaic applications, identifying factors influencing BIPV adoption and highlighting the importance of design integration in achieving meaningful integration. In conclusion, initiatives such as Task 41 and Task 56 within the International Energy Agency's Solar Heating and Cooling Programme, as well as Task 15 IEA PVPS, underscore the importance of advancing solar integration in architectural design and building performance through the collection of successful international projects.…”
