Environmental responsibility has become a pivotal force in architecture shaping the contemporary landscape of building practices. Demand for low-carbon, energy-efficient buildings has surged against the backdrop of pressing global challenges such as climate change and the depletion of natural resources. This has led to the emergence of the field of low-carbon architecture, a discipline that not only cares about aesthetics but also prioritizes environmental harmony and energy conservation. The study therefore provides a comprehensive review of innovative design and construction techniques in low-carbon architecture in general, with a particular focus on strategies that enhance energy efficiency. As the world grapples with the need to mitigate the environmental impact of urban expansion, architects are increasingly turning to forward-thinking solutions to create buildings that not only meet the functional and aesthetic needs of occupants but also address the planet's concerns. The study explores a range of approaches, from passive design principles that harness natural elements to advanced technologies that optimize energy consumption. By examining the integration of sustainable materials, construction methodologies, and advanced technologies, this review aims to provide a nuanced understanding of how innovative design and construction techniques can contribute to the creation of environmentally responsible structures. From the use of recycled materials to the integration of renewable energy sources, every aspect of green architecture is examined for its potential to revolutionize the way we envision, design, and build structures in the 21st century. Navigating this exploration, our goal is to contribute to the growing body of knowledge that informs and inspires construction professionals, policymakers, and researchers. By synthesizing current trends, challenges, and achievements, this review seeks to pave the way for a sustainable future where architecture seamlessly blends with the environment.
