Abstract
En 中文
• GR, CR, and SCR rooftops enhance RPVSP output and cool the microclimate, making rooftops dual assets for energy and thermal resilience. • SCR+ RPVSP systems cut panel temps by 27.3 °C and boost energy by 14.3%, proving superior for urban cooling and RPVSP efficiency. • A 1.0 ms−1 wind rise cools panels by 18.3 °C and raises output by 9.9%, revealing wind's key role across rooftop material typologies. • SCR + RPVSP improved panel efficiency by 2.0% (0.8–2.7%), outperforming CR + RPVSP (1.3%) and GR + RPVSP (0.7%) under daytime urban heat conditions. • SCR+ RPVSP setups met up to 104.6% of cooling needs, showing potential for air conditioning load offsets in urban net-zero designs.
