Experimental demonstration reveals improvements in cooling load and thermal performance in urban green roofs, suggesting enhanced adaptation strategies.
Key Points
Evaluate the impact of bio-solar green roofs on urban heat adaptation and their energy system benefits.
Compared performances of conventional, green, photovoltaic, and bio-solar green roofs.
Conducted tests under clear-sky summer conditions in Lahore, Pakistan.
Collected data on meteorological, thermal, moisture, and PV power every minute.
Bio-solar green roofs demonstrated the lowest outer surface temperature.
Diurnal amplitude reduced by approximately 19% compared to conventional roofs.
Thermal response delayed by about 21% in the bio-solar green roof assembly.
