The private sector plays a pivotal role in advancing sustainable construction within a 24-hour economy, ensuring that economic growth aligns with environmental responsibility. According to Guim Costa, Artistic Director at Vilalta Studio, sustainability is not just a trend but a necessity for the future of construction.
“With energy stability being a challenge in many markets, designing and constructing energy-efficient or self-sufficient buildings creates significant value,” Costa explains. “A building capable of generating its own energy offers a strong competitive advantage.”
Vilalta Studio, known for its expertise in sustainable architecture across Africa, has demonstrated this vision through projects like Lideta Mercato in Addis Ababa. The innovative marketplace incorporates solar energy solutions, ensuring not just power generation but also long-term operational stability. The project exemplifies how sustainable design can enhance resilience, especially in regions where energy supply remains inconsistent.
Costa emphasizes that the private sector must take the lead in embedding sustainability into economic development. “Accelerating construction timelines in societies that urgently require infrastructure adds even greater value,” he says. “Efficient and sustainable construction is essential to creating urban spaces that support a 24-hour economy, where businesses and communities can function seamlessly at all times.”
Beyond energy efficiency, sustainable construction also encompasses responsible material sourcing, climate-responsive design, and minimizing environmental impact. By integrating these principles, private firms can shape the future of urban development while fostering long-term economic stability.
As global discussions around sustainable construction and the 24-hour economy continue to evolve, Vilalta Studio remains committed to fostering impactful exchanges and driving innovation in energy-efficient building design. With projects like Lideta Mercato setting a benchmark, the firm continues to showcase how sustainability can be a powerful force in shaping the cities of tomorrow.
