In collaboration with Glass to Power, Matteo Giovanardi and Alessandro Pracucci from Levery have published a new research article in AGATHON, an international architecture journal. The research, conducted within the “Mass Customization 2.0 for Integrated PV” (MC 2.0) project, explores the complex challenge of integrating BIPV into continuous facade systems. As a case study, a patented BIPV photovoltaic glass from Glass to Power was used. This integration presents a high level of complexity due to interactions with other building systems, production and installation implications, and the need to ensure overall system performance. The design process prioritized meeting specific architectural, technological, economic, and environmental requirements, balancing aesthetics with functional performance to encourage market adoption.

Strategies for managing complexity

The complexity of BIPV systems, due to their numerous requirements and multidisciplinary nature, requires specific management strategies. A systemic and integrated approach is crucial, considering the physical and functional relationships between components from the earliest design stages. This involves analyzing compatibility between systems and materials throughout the entire production process. Modular and circular design principles offer benefits in terms of economic efficiency and sustainability, enabling scalable production and facilitating maintenance, repair, and reuse throughout the BIPV system’s lifecycle. A low-tech approach, favoring simple and reliable solutions, reduces costs and the need for specialized labor. Simplified, plug-and-play installation is essential, ideally designed for series wiring and installation alongside the facade system. Future-proof design, incorporating flexibility and adaptability, ensures long-term durability and performance. This includes careful consideration of component optimization, material selection, and planned obsolescence. Finally, a multidisciplinary design approach, involving architectural, technological, and photovoltaic expertise, is essential for developing innovative and sustainable BIPV solutions that meet market demands.

Conclusions and future perspectives

With the evolution of the European and national regulatory frameworks and with the introduction of more ambitious targets for achieving climate neutrality by 2050, interest in BIPV technologies is growing. The integration of renewable energy in buildings offers a strategic opportunity for the development of energy-independent cities. This article contributes by defining strategies to manage the complexity of BIPV system design and improve their market diffusion. A significant challenge is the limited availability of a production chain specialized in supplying photovoltaic components for BIPV products. While the photovoltaic sector has reached industrial maturity, further progress is needed in the development of BIPV-specific architectural elements. Finally, standardized and consistent product certifications for integrated systems are crucial to promote the adoption of BIPV technologies and contribute to the achievement of climate neutrality targets for the built environment.
