The main aim of the energy and environmental prediction (EEP) model is to provide an auditing tool for quantifying energy use and emissions in cities to assist in planning for sustainable development. The EEP model can be used as a planning and policy tool that will allow local government to select sites for development that will assist in the drive for sustainability. It can also be used as an impact assessment tool to determine the impact of proposed developments by assessing likely travel patterns and energy use. The computer-based model provides an integrative method for domestic, commercial, industrial process and transport sectors of the built environment to predict and account for energy use within a region so that plans can be made to reduce carbon dioxide and other emissions.
