A major push to install rooftop solar panels on Chinese buildings is putting the nation on track for another record-setting year on renewable energy.
By 2019, the total building area in China is about 64.4 billion m 2, and urban and rural residential buildings account for 79% of the entire building area, which is about 51 billion m 2. Moreover, compared with other countries, China's per capita residential building area is close to the level of developed countries (RCBEE, 2021).
Li et al. pointed out that the energy consumption of green residential buildings in China decreases with the increase of star ratings, but also pointed out that the specific projects are characteristic because of the different locations in climate zones, cooling/heating schedules, and operation management (Li et al., 2015).
