Abstract :In the context of rising global energy demands driven by population growth and urbanization, the construction industry significantly contributes to greenhouse gas emissions during the construction phase and subsequent energy consumption. Fossil fuel dependency for heating and energy needs exacerbates climate change, necessitating urgent solutions. Algal technology emerges as a promising strategy for green building practices, addressing energy efficiency and emissions reduction. Algae\'s unique ability to absorb carbon dioxide (CO2) through photosynthesis is harnessed by deploying photobioreactors on building exteriors. Studies indicate that each kilogram of dry algae consumes 1.83 kg of CO2 while offering applications as organic fertilizer, oil, and protein sources. This technology not only diminishes CO2 emissions but also transforms wastewater and generates bioenergy, catering to building energy requirements. Algal technology\'s economic and environmental significance becomes evident through carbon capture, energy generation, and circular waste management, aligning with sustainability principles. This study highlights the potential of algal technology to shape the future of environmentally conscious construction practices, providing avenues for reduced emissions, efficient energy utilization, and sustainable development.
