Green buildings using renewable energy are developing as the world pursues sustainability. This abstract covers distributed renewable power planning and construction for energy efficiency, conservation, and built environment sustainability. Distributed solar, wind, biomass, and geothermal for green buildings. Local generation lowers grid dependency in distributed energy systems. Site study, energy demand assessment, and renewable energy source selection for the building's needs and location are design aims. Smart grids and energy storage boost renewables. Energy-efficient passive design, sustainable materials, and creative architecture complement distributed renewable power sources throughout construction. Cost savings, renewable energy ROI, and green building's environmental advantages are examined. Renewable energy may boost green building safety, security, and ecology. Distributed renewable energy green buildings fight climate change and promote sustainability.
