Mumbai boasts the presence of 12% of the country's 2,000 LEED-certified green buildings, placing it second only to Bengaluru. These buildings span diverse sectors, from educational institutions and hospitality establishments to commercial offices and retail outlets, all united under the banner of LEED, or Leadership in Energy and Environmental Design. LEED, a globally recognised green building rating system developed by the US Green Building Council (USGBC), evaluates a building's environmental performance and sustainability across various criteria, including energy efficiency and indoor environmental quality. The proliferation of LEED-certified structures in Mumbai underscores a growing emphasis on sustainability within the city's rapidly evolving urban landscape. With heat waves, water scarcity, and climate change concerns looming large, the adoption of green building practices has become imperative. This trend reflects a broader global movement towards environmentally responsible construction methods and underscores Mumbai's commitment to mitigating its environmental impact. According to Peter Templeton, President of USGBC, India ranks as the fourth largest market for LEED, with over 2.6 million square feet of space being certified daily. This surge in green building activity underscores a shift towards more sustainable development practices within the Indian real estate industry. Notably, LEED certification offers tangible benefits beyond environmental stewardship, including increased marketability and higher rental premiums for both residential and commercial properties. The rise of green building certifications also reflects a broader paradigm shift towards sustainable urban planning and design. Nyrika Holkar, Executive Director of Godrej & Boyce, emphasises the need for resilient urban development strategies in light of the on-going climate crisis. She advocates for a holistic approach that encompasses everything from architectural design to material sourcing, with green building certifications serving as a relevant framework for guiding this transition. LEED certification, achieved through a rigorous review process, promotes energy efficiency, water conservation, and healthy indoor environments. The latest version of LEED, known as LEED v5, emphasises flexibility and performance-based outcomes to align with global sustainability targets. Building owners can improve their LEED rating through strategies such as energy-efficient upgrades and water conservation measures, supported by real-time performance analytics. Despite the numerous benefits of LEED certification, some challenges persist, particularly concerning existing buildings. Retrofitting older structures to meet LEED standards can be costly and complex, leading to hesitancy among developers. Additionally, there are concerns about the applicability of LEED criteria to diverse climatic contexts, such as Mumbai's reliance on passive cooling methods. Architects and urban planners are increasingly grappling with these challenges as they seek to balance sustainability with practicality in Mumbai's built environment. From innovative design solutions to community engagement initiatives, there is a growing recognition of the need for holistic approaches to sustainable development. As Mumbai continues to evolve, the integration of green building practices will play a crucial role in shaping a more resilient and environmentally conscious cityscape. (Source: ET Infra)
