Evaluates how green roofs and street trees lower temperatures across the built environment.

Dr Grace Lim evaluates how green roofs and street trees lower temperatures across the built environment. Her experiments measure the cooling a single tree or planted roof delivers, and how those small effects add up across a street, a block, and a district.

By grounding greening guidance in measured performance, she helps city teams choose interventions that genuinely cool, rather than ones that simply look green on a plan.
