This research article explores green building techniques within the context of the Climate Framework Agreement, emphasizing sustainable practices to reduce environmental impact. It discusses various green building rating systems, such as BREEAM, LEED, and GRIHA, and proposes a new assessment framework based on principal component analysis. The framework identifies nine key components, including site selection, environmental impact, and economic considerations, to evaluate building sustainability. The study highlights the importance of energy-efficient design, water conservation, sustainable materials, waste reduction, green roofs and walls, and indoor environmental quality. It also emphasizes the integration of biofuels in green buildings, such as using biodiesel in heating systems, biogas in combined heat and power systems, and solar panels for electricity generation. The article outlines strategies for energy-efficient design, including passive design strategies, high-performance insulation, and energy-efficient HVAC systems. Water conservation methods include rainwater harvesting, greywater recycling, and drought-resistant landscaping. Sustainable materials are chosen based on their environmental impact, with a focus on locally sourced, recycled, and rapidly renewable materials. Waste reduction and recycling are addressed through construction waste management, recycling of demolition debris, and modular construction. Green roofs and walls are highlighted for their benefits in insulation, stormwater management, and biodiversity. Indoor environmental quality is improved through proper ventilation, low-emission materials, and natural light integration. Life cycle assessment is used to evaluate the environmental impact of buildings throughout their lifespan. The study concludes with recommendations for integrating climate-responsive design, carbon-neutral construction practices, renewable energy integration, resilient infrastructure planning, ecosystem services preservation, circular economy principles, community engagement, and monitoring and reporting. The research underscores the importance of green building techniques in achieving sustainable development and aligning with global climate goals.This research article explores green building techniques within the context of the Climate Framework Agreement, emphasizing sustainable practices to reduce environmental impact.
