Developing the rooftop photovoltaic (PV) system was beneficial to generate electricity and reduce carbon emissions in buildings. This paper presented the rooftop PV modeling method to support urban building energy modeling (UBEM) using the prototype UBEM method and the building-by-building UBEM method.
With the growing need for sustainable urban energy solutions, rooftop solar photovoltaic (PV) systems can play a pivotal role. However, the effective integration of solar energy into urban landscapes faces challenges in spatial planning, resource optimisation, and stakeholder engagement.
Rooftop PV gradually became an important part of building energy systems, helping to generate electricity and contribute to carbon neutrality. [4, 5]. Urban building energy modeling can be used to obtain the performance of building clusters and estimate the energy-saving effect of different technologies .
The PV modeling method could provide suggestions for PV installation at the urban scale. In this research, rooftop PV models were developed for buildings with different types of rooftops, including rectangular flat rooftops, pitched rooftops, and arbitrary-shape flat rooftops.
The PV power generation decreased by 5.75 % because of shading impact. The actual PV available area was 10.00 % less compared to the prototype UBEM method. Developing the rooftop photovoltaic (PV) system was beneficial to generate electricity and reduce carbon emissions in buildings.
