This paper provides a comprehensive review of innovative design and construction techniques in green architecture, focusing on strategies to enhance energy efficiency. It explores various approaches, including passive design principles, green roofs, efficient insulation systems, and the use of sustainable materials. The paper also discusses emerging technologies such as bio-concrete and self-healing materials, which enhance structural resilience and eco-friendliness. Advanced building systems like smart grids and energy-efficient HVAC systems are highlighted for optimizing energy performance. The integration of renewable energy sources, such as solar panels and wind turbines, is emphasized for promoting energy self-sufficiency and reducing greenhouse gas emissions. Real-world case studies, such as Bosco Verticale, The Edge, and One Central Park, illustrate the practical application and success of these techniques. The paper concludes by addressing future trends and challenges, emphasizing the need for policy support, education, public awareness, and collaborative efforts to promote sustainable construction practices.This paper provides a comprehensive review of innovative design and construction techniques in green architecture, focusing on strategies to enhance energy efficiency.
