Funded by the Hong Kong University Grant Committee, a multidisciplinary research project team for Environmentally Responsible Architecture and Urban Context (ERAU) was formed to coordinate the knowledge and efforts of its research partners, to provide both the setting and the resources to study environmental technology and building performance. The project is comprised of five major components: (a) urban visual sustainability; (b) urban wind environment and natural ventilation; (c) acoustic quality for urban planning and building design; (d) thermal comfort and building energy efficiency; and (e) natural lighting for urban space and architecture. The integrated project approach supported by design computing tools (e.g., Virtual Reality) demonstrates a new paradigm for Hong Kong's urban planning and architecture design. Case studies are used to illustrate the technology developed by the research group and the preliminary outcomes of our collaboration projects.
