The Solar City Project by University of Ballarat evaluates the drivers of power consumption and CO2 emissions in Loddon Mallee and Grampians regions. Factors such as adoption of solar energy technologies, geographical and physical characteristics of dwellings were assessed to evaluate power consumption. The project found that dark and intermediate colour roofs, older constructions, and higher PV capacity contribute to lower power usage. On the other hand, houses with more lamps, tinted windows with curtains, and dark coloured roofs made of timber and concrete blocks utilize more power. The project recommends using higher PV capacity, windows with double glazed blinds, older constructions, and higher insulation capacity to PV to save power.
