Green building has emerged as a significant response to the challenges posed by climate change and rapid urbanization. As the world faces increasing threats from rising global temperatures, extreme weather events, and resource depletion, the need to rethink how we design, construct, and operate buildings has never been more urgent. Buildings account for a substantial proportion of global energy consumption and greenhouse gas emissions, making them a central focus of both mitigation and adaptation strategies to climate change. Green building represents an integrated approach that combines sustainable design, resource efficiency, and environmental responsibility with the goal of minimizing negative impacts on the natural environment while enhancing the health and well-being of occupants. Its importance lies in its ability to simultaneously reduce the causes of climate change and prepare communities for its inevitable consequences. The importance of green building is particularly evident in its contribution to mitigation of climate change. Conventional construction practices often rely heavily on energy derived from fossil fuels, non-renewable resources, and unsustainable materials, leading to high emissions of carbon dioxide and other greenhouse gases. Green building addresses this by promoting energy-efficient systems such as solar panels, wind energy integration, geothermal heating, and advanced insulation techniques. By reducing reliance on fossil fuels, buildings can play a crucial role in lowering emissions and supporting a shift toward renewable energy. Moreover, green buildings emphasize efficient use of resources such as water, land, and materials, thereby minimizing waste and reducing the environmental footprint of construction. For instance, the use of recycled steel, reclaimed wood, or low-carbon cement can significantly cut emissions embedded in building materials. In addition to mitigation, green building is central to adaptation to climate change. Cities across the globe are experiencing more intense heatwaves, flooding, storms, and unpredictable weather patterns. Green buildings are designed with resilience in mind, ensuring that they can withstand environmental stresses and protect inhabitants. Features such as green roofs, rainwater harvesting, and permeable surfaces reduce urban heat island effects, prevent flooding, and support water conservation. Passive design strategies, like natural ventilation, shading, and daylight optimization, help maintain comfortable indoor temperatures even during extreme weather, reducing
