Masdar City’s Net-Zero Model Sets Sustainability Benchmark, but AI Holds Key for Aging Cities, Experts Claim
A new white paper from Masdar City highlights the UAE’s leadership in net-zero urban development. Energy experts say that net-zero strategies could also be applied to most cities worldwide, even when the biggest challenge is in retrofitting old existing buildings. Built as a purpose-driven net-zero city, Masdar eliminates the need for future retrofits by integrating energy efficiency from the start. However, decarbonization remains a challenge for most cities worldwide, where most buildings are decades old. Experts argue that AI-driven energy management could provide a viable solution, optimizing real-time energy use in existing infrastructure without the financial burden of deep renovations. “Masdar City demonstrates what’s possible when sustainability is built into urban planning from the ground up,” said Donatas Karčiauskas, CEO of Exergio, a company that implements AI-based energy efficiency tools in commercial buildings. “But most of the world’s cities don’t have that luxury. The question is: how do we bring net-zero strategies to older buildings without breaking budgets? AI is the most practical answer.” Buildings account for 40% of the EU’s final energy consumption and contribute 36% of its energy-related emissions. In Europe alone, 75% of buildings were constructed before 2000 and remain energy-inefficient, with 85-95% expected to still be in use by 2050–the net-zero deadline. This pattern is reflected globally, particularly in dense urban areas where outdated infrastructure dominates city skylines. While Masdar’s white paper highlights the importance of renewable energy, smart grids, and green building certifications like LEED, these approaches favor new developments and regions with access to significant capital. According to Karčiauskas, for cities with aging infrastructure, the challenge lies in improving operational efficiency rather than rebuilding from scratch. “Certifications like LEED are useful for ensuring new buildings meet sustainability benchmarks,” he noted. “But they don’t address how older buildings actually operate. Without real-time energy monitoring, sustainability […]
