AI is revolutionizing sustainable building construction and design by optimizing factors like energy efficiency, sustainability, and safety. Generative AI aids in optimizing building orientation, glazing ratios, shading, and insulation, resulting in more sustainable buildings. It also enhances structural optimization, leading to buildings that withstand external pressures while minimizing material use. In urban planning, generative AI optimizes traffic flow, public space design, building permitting processes, disaster preparedness, and urban development.
