Jakarta, INTI - A recent study by Chinese scientists reveals that installing solar panels on building exteriors, known as facade-integrated photovoltaics (FIPV), has the potential to generate substantial amounts of electricity while reducing carbon emissions and urban energy demand.
Significant Power Potential from Building Facades
The research, led by the Institute of Geographic Sciences and Natural Resources Research under the Chinese Academy of Sciences and published in Nature Climate Change on Friday, March 27, 2026, highlights the untapped potential of vertical building surfaces.
Using global data on building geometry and weather conditions, the researchers estimate that FIPV could generate approximately 732.5 terawatt-hours of electricity annually worldwide.
This amount is considered sufficient to meet the electricity needs of millions of urban households.
In addition, installing panels on building walls could reduce overall building energy consumption by an average of 8.1 percent, particularly for cooling, due to the shading effect provided.
Reducing Emissions Requires Policy Support
The study notes that the combined benefits of electricity generation and energy efficiency could significantly contribute to lowering global carbon emissions.
If widely implemented by mid-century, FIPV technology is projected to reduce cumulative carbon emissions by up to 37.7 gigatons.
“As climate change drives more extreme heat and increases urban energy demand, this study highlights an overlooked opportunity to make buildings more energy-efficient and resilient,” said Professor Yao Ling of IGSNRR.
The researchers emphasize that successful implementation will depend on appropriate policies, careful planning, and adaptation to local conditions to fully maximize its benefits.
Conclusion
The study highlights facade-integrated photovoltaics (FIPV) as a promising solution to transform urban buildings into active energy producers. By combining renewable energy generation with improved efficiency, this approach could play a key role in reducing carbon emissions and supporting sustainable city development, provided it is backed by strong policies and proper implementation strategies.
