This chapter describes an integrated assessment model for city-scale urban development that links the energy used in passenger transport (public and private) and residential in-house energy use. The model divides the urban region into disjoint subregions, the core of the model being centered on residential location choice, which is calibrated by population, demographic characteristics, and building types, leading to preferences for each subregion based on household type. Submodels are subsequently used to calibrate different rates of energy in accordance with household and demographic factors.THis generates a picture of consumption patterns across the metropolitan area, enabling an appreciation of spatially heterogenous factors such as differing levels of greenhouse gas (GHG) emissions, alongside variations in the distribution of infrastructures that can create considerable variation in energy consumption between districts within cities. The energy impacts of policy decisions that affect, by way of example, where new housing is to be built and of what type, can then be simulated. The workings of the model are demonstrated in the chapter using data on Sydney, Australia, as a case study, with the research offering a policy scenario to city officials to monitor its progress towards a 2030 vision for a sustainable Sydney.
