Building-integrated photovoltaics (BIPV) represent a crucial component in achieving nearly zero-energy cities, as examined in the paper The Contribution of Building-Integrated Photovoltaics (BIPV) to the Concept of Nearly Zero-Energy Cities in Europe. This paper delves into the role of BIPV in urban energy transitions and highlights both its potential and the challenges in widespread adoption across Europe. BIPV systems can transform buildings into energy producers by integrating solar panels directly into the architectural elements of facades and roofs, a significant step towards reducing cities' carbon footprints.
Despite the evident environmental benefits, the paper identifies several barriers to the implementation of BIPV systems. These barriers are classified into five stages: decision, design, implementation, operation and maintenance, and end of life. At the decision stage, initial costs and market complexity hinder adoption, while the design phase is challenged by regulatory standards and technical issues, such as system weight and health and safety concerns. Implementation barriers include difficulties with system fixing and commissioning. Once operational, systems require consistent maintenance, monitoring, and protection against water penetration. Finally, end-of-life challenges, such as material recovery and system demolition, add further complexity to the lifecycle of BIPV systems.
Stakeholders from various sectors must collaborate to overcome these barriers. Architects and urban planners are vital in integrating BIPV into designs from the early stages. Policymakers need to streamline regulations and provide financial incentives, while manufacturers must continue to improve the efficiency and cost-effectiveness of BIPV technology. Installers and contractors play a key role in ensuring the systems are implemented correctly and meet performance standards. Additionally, end-users must be educated on the long-term benefits of BIPV to foster wider adoption.
One of the paper’s crucial takeaways is the importance of collaborative solutions. For BIPV to succeed, a multi-stakeholder approach is necessary, where regulatory support, technological innovation, and societal awareness work hand in hand. While technical and financial challenges remain, the potential for BIPV to turn cities into nearly zero-energy environments by 2030 is a realistic goal. This transition will depend on the continued development of efficient technologies and the willingness of cities to embrace forward-thinking energy solutions.
The adoption of BIPV in Europe is not only feasible but also essential for achieving climate goals. By classifying the barriers and recognizing the stakeholders involved, this paper provides a roadmap for overcoming the challenges in the widespread rollout of BIPV technology. With strategic planning and collaboration, European cities can lead the way in urban energy transitions, setting a global example for sustainable development.
