Can rooftop photovoltaic systems support urban building energy modeling?
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.
Should building energy models be based on rooftop PV?
Establishing building energy models with rooftop PV could help estimate the building energy consumption and rooftop PV power generation, which was beneficial in guiding the design and installation of PV systems.
Why is rooftop PV important in urban building energy modeling?
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 .
Why is rooftop PV important?
With the development of solar energy technology, more and more buildings installed PV systems, including rooftops and facades . Rooftop PV gradually became an important part of building energy systems, helping to generate electricity and contribute to carbon neutrality. [4, 5].
What is the largest PV power generation per roof area?
Case 24 achieved the largest PV power generation per roof area of about 115.83 kWh/m 2 in scenario 3. The PV power generation per roof area was calculated by multiplying the power generation per PV area by the PV available area ratio. The ratio of the PV area to the roof area was the main factor affecting rooftop PV power generation.
How a rooftop PV system can improve power generation in Changsha?
The developed rooftop PV models were capable of different types of rooftops. Decreasing the interrow spacing could improve PV power generation by 26 % at most. The largest PV power generation per roof area in Changsha was 110.81 kWh/m 2. The PV power generation decreased by 5.75 % because of shading impact.
