In the heart of Morocco, a groundbreaking study is reshaping the future of sustainable construction and energy independence. Mohamed Ouazzani Ibrahimi, a researcher from the Higher School of Technology at Université Sidi Mohamed Ben Abdellah in Fez, has pioneered an innovative approach to designing net-zero-energy buildings (NZEBs) tailored to hot, dry climates. His work, published in the journal ‘Buildings’ (which translates to ‘Buildings’ in English), offers a blueprint for integrating eco-design and building-integrated photovoltaics (BIPV) systems, setting a new standard for the energy sector.
Ibrahimi’s research focuses on the Fes-Meknes region, where the demand for energy-efficient buildings is growing. By comparing conventional concrete brick structures with eco-constructed alternatives using biobased wooden materials, he discovered that wooden construction can significantly reduce annual energy consumption by 33.3% and operational CO2 emissions by 50%. “The enhanced thermal insulation and moisture-regulating properties of biobased materials play a crucial role in achieving these savings,” Ibrahimi explains.
But the innovation doesn’t stop at construction materials. Ibrahimi’s study also delves into the optimization of solar energy systems. By analyzing multiple configurations, he identified an optimal hybrid off-grid system that combines rooftop photovoltaic (PV) panels, BIPV, and lithium-ion battery storage. This system achieves a remarkable 100% renewable energy fraction, producing an annual output of 12,390 kWh. “This system not only ensures full grid independence but also lowers the electricity cost to $0.70/kWh, enhancing occupant comfort,” Ibrahimi notes.
The financial implications of this research are substantial. While the hybrid system incurs a higher net present cost of $45,708 USD, the long-term benefits—including energy independence and reduced operational costs—make it a compelling investment for the energy sector. “This integrated approach combines biobased construction, lifecycle-informed energy modeling, and HOMER-optimized PV/BIPV systems, tailored to a hot, dry climate,” Ibrahimi adds.
The study provides a replicable framework for designing NZEBs in Morocco and similar arid regions, supporting the low-carbon transition and informing policy, planning, and sustainable construction strategies. As the world grapples with climate change and the need for sustainable energy solutions, Ibrahimi’s research offers a beacon of hope and a practical path forward.
This research is poised to shape future developments in the field, encouraging architects, engineers, and policymakers to adopt integrated, sustainable approaches to building design and energy management. By leveraging biobased materials and advanced solar technologies, the construction and energy sectors can achieve significant reductions in energy consumption and emissions, paving the way for a more sustainable future.
