Thermal Performance of Green Roof Retrofit
Green areas have diminished in big cities. Increasing temperatures and deterioration of air quality is a common result. Consequently, there is a rise in air pollution and greenhouse gas emissions, costs of air conditioning, and mortality and heat‐related illness. Owing to the lack of space in urban areas, green roof retrofit is a feasible alternative to counter this problem. Green roofs improve the insulating qualities of buildings, attenuating heat exchange through inadequately insulated and poorly sealed roof structures. This research reports on an experiment on two small‐scale metal roofs in Sydney (Australia) and Rio de Janeiro (Brazil) to assess the thermal performance of portable green roof modules. At each site, two identical roofs, one covered with modular lightweight trays planted with succulents and the other not, had their internal temperature recorded simultaneously and compared. Green roofs were shown to attenuate housing temperatures, indicating that green roof retrofitting could lower the cooling energy demand considerably.
