🔬研究者:Provides a conceptual framework for climate-adaptive BIPV integration, useful for further empirical studies.

🏢実務担当者:Offers guidance on selecting BIPV configurations based on climate and urban context for building projects.

🏛政策担当者:Highlights the potential of multi-surface BIPV in urban decarbonization, informing building codes and incentives.

Purpose: Building-Integrated Photovoltaics (BIPV) are increasingly recognised as a key technology for urban decarbonisation and net-zero buildings. Since buildings account for approximately 30–40% of global final energy consumption and urban areas continue to experience rapid growth in cooling demand, integrating renewable energy generation directly into building envelopes has become increasingly important. However, the performance and suitability of BIPV systems strongly depend on climatic conditions, urban morphology, façade orientation, and building envelope configuration. This contribution explores climate-adaptive BIPV concepts for sustainable urban buildings and discusses how different climatic contexts influence optimal integration strategies. Methodology: The paper presents a conceptual synthesis of recent developments in multi-surface BIPV integration across roofs, façades, balconies, and semi-transparent glazing systems. Perspectives from representative global climates, including tropical, arid, temperate, and cold regions, are comparatively discussed with emphasis on solar availability, façade utilisation potential, cooling demand interaction, and urban sustainability objectives. Main findings: The analysis indicates that climate conditions significantly influence preferred BIPV integration strategies. In high-irradiance regions, roof-integrated systems can typically achieve annual yields exceeding 1400–1800 kWh/kWp, whereas façade-integrated systems become increasingly attractive in dense urban areas and higher latitudes where vertical solar capture improves seasonal performance. Multi-surface BIPV integration can substantially increase the active solar area of buildings compared to roof-only installations, particularly in high-rise urban environments. Semi-transparent and multifunctional BIPV systems additionally contribute to daylight management, glare reduction, and thermal control, supporting climate-responsive building operation. Recommendations: Future urban BIPV development should move beyond static roof-based installations towards adaptive multi-surface building envelope concepts integrating climate-responsive design, smart control approaches, and urban energy system interaction to support resilient and low-carbon cities.
