Analysis on Thermal Measuring of Rooftop Farming Garden a Case Study of Julong Residential District in Zhongshan

Urban Farm DB summary

This study reports on a thermal experiment and energy saving analysis of rooftop farming conducted in Zhongshan, Guangdong Province, China, in August 2011. External and internal surface temperatures of roofs with and without greening were measured using the same climate parameters. The experiment results indicate that green roofs with urban farming contribute to modulating air temperature in building interior spaces, showing lower external surface temperatures than normal flat roofs during hot summer days. The vegetated green roof system was found to effectively lower surface temperature by 6 °C and save 18.7% electric power compared to traditional flat roofs.
