Buildings and other engineered structures that form cities are responsible for a significant portion of the global and local impacts of climate change. Consequently, the installation of building integrated renewable energy sources such as photovoltaic or solar thermal systems on building rooftops is being widely investigated. Although the advantages for individual buildings have been studied, as yet there is little understanding of the potential benefits of urban scale implementation of such systems. Here we report the development of a new methodology for assessing the potential capacity and benefits of installing rooftop photovoltaic systems in an urbanized area. Object oriented image…

 Highlights: ► New method assesses the potential capacity of urban-scale rooftop PV systems. ► Object oriented image analysis is combined with geographical information systems. ► 10% of the total electricity demand can be met by the proposed PV systems.
