The effect of green roof configurations including trees in a subtropical climate: A co-simulation parametric study

There is an increased interest in including green roofs building legislation to enable infrastructure and improve the built environments. Yet, trees on buildings particular, have received little attention. This paper presents a parametric study effect of nine roof configurations outdoor indoor temperatures associated cooling demand under three urban densities by coupling ENVI-met EnergyPlus simulation software. novel as it introduces performance that include canopy compares their with typical only low vegetation. Results show 1) has greater impact reducing rather than temperatures; 2) perform better compared without trees, temperature up 7.20 °C air conditioning electric loads 60%; 3) excel thermal roofs, even if latter higher coverage percentage. Therefore, authors recommend using for rating instead Furthermore, varies density type, suggest specifying most appropriate configuration each neighbourhood smart city models maximise benefits address city's needs.
