Urban construction faces increasing pressure to meet complex regulatory requirements and ambitious sustainability goals, especially within the context of rapidly evolving smart cities. This paper introduces a novel AI-powered Sustainable Building Bot (SBB), a modular system designed to enhance regulatory intelligence (RI) and sustainability assessment intelligence (SAI). Leveraging generative AI technologies, notably LangChain and GPT-3.5, the SBB comprises 10 bot variants and a replicable evaluation framework. Results demonstrate significant gains over manual methods, including faster response times, fewer errors, and improved productivity. However, human oversight remains essential to ensure contextual accuracy, ethical use, and alignment with evolving regulatory landscapes.
