They also ascertained that the maximum permitted EUI by net-zero energy status is 17–28 kWh/m2a. Buildings powered by solar energy should not exceed 10 floors in height if they have to achieve a net-zero energy performance.
Especially the residential buildings, which occupy the main part of a city, have a great potential to utilize the solar resources on building surfaces (Limin et al., 2017). However, the diversity of residential buildings and complexity of urban environments make it difficult to efficiently utilize solar energy.
Over 20 percent of the total solar capacity installed in the U.S. corresponds to residential installations. This segment has grown in recent years, reaching some 3.6 million installations in 2022. Increasing household electricity bills are a large motivator for the installation of residential solar systems.
The solar energy potential of building roofs and facades are evaluated. The global sensitivity analysis is used to prioritize the influential parameters. The characteristics of solar potential for thousands of buildings are analyzed. The quantitative analysis regarding the PV utilization strategies is presented.
The characteristics analysis was conducted to illustrate the distribution of solar energy potential for building surfaces. Then, the quantitative analysis was presented to provide the PV utilization strategies for residential building roofs and facades in different block environments. The main conclusions can be drawn as follows:
The massive solutions regarding the PV utilization strategies can be applied for residential buildings in diverse urban environments, which can adapt to the widespread use of solar technology in urban buildings and promote the Carbon Neutral of cities.
