In the sun-scorched landscapes of southern Algeria, the city of Ouargla is becoming a unique laboratory for a groundbreaking study that could reshape how we think about urban planning and solar energy. Meskiana Boulahia, a researcher at the Ecole Polytechnique d’Architecture et d’Urbanisme (EPAU), has been delving into the intricate relationship between urban form and solar energy potential, with findings that could have significant commercial implications for the energy sector.
Boulahia’s research, published in the Proceedings of the International Conference of Contemporary Affairs in Architecture and Urbanism-ICCAUA, focuses on how different urban forms can maximize solar energy capture. By examining three distinct types of urban layouts—differentiated by street morphology, building use, and environmental context—Boulahia has uncovered that the design of a city can dramatically influence its solar energy potential. “The urban form has a profound impact on solar energy potential,” Boulahia explains. “This means that by carefully planning urban layouts, we can significantly boost photovoltaic energy production.”
The study involved creating 3D models of different urban forms and running numerical simulations to evaluate solar irradiation distributions on building roofs. This meticulous approach allowed Boulahia to identify which urban forms are most conducive to solar energy harvesting. The findings suggest that thoughtful urban design can lead to a substantial increase in photovoltaic energy production, offering a compelling case for integrating solar energy considerations into urban planning from the outset.
For the energy sector, this research opens up new avenues for collaboration with urban planners and architects. By understanding how urban forms can be optimized for solar energy, developers and energy providers can create more sustainable and cost-effective projects. This could lead to a future where cities are not just designed for aesthetics and functionality, but also for energy efficiency and sustainability.
Boulahia’s work underscores the importance of interdisciplinary approaches in tackling global challenges. “Energy planning is not just about installing solar panels; it’s about integrating renewable energy into the very fabric of our cities,” she notes. This holistic view could inspire a new generation of urban developments that prioritize both environmental sustainability and economic viability.
As the world continues to grapple with climate change and the need for sustainable energy solutions, Boulahia’s research provides a roadmap for how cities can be designed to harness the power of the sun more effectively. By bridging the gap between urban planning and energy production, this study could pave the way for smarter, greener cities that are better equipped to meet the energy demands of the future.
