Green Roof Retrofit and the Urban Heat Island
Global climate change and the UHI phenomenon – whereby cities absorb and release more heat than the surrounding countryside – carry growing potential to make urban life at particular times and places an exercise in low‐grade misery. The mitigating role of urban vegetation and green spaces, reflective materials and strategies for reducing the release of heat from human activities like transport and air conditioning are increasingly well understood. Green roofs are recognised as playing a part in UHI mitigation. This chapter reviews the literature around the microclimatic effects of green roof retrofitting and presents a model based on remote‐sensing data for metropolitan Sydney, Australia. We apply this model to explore the effects of installing extensive green roofs on 100% and 50% of rooftops across the variety of urban form typologies which characterise Sydney's built environment. The results suggest a modest but real reduction in heat island effects.
