Green roofs can cool cities and save energy: modelling
New research shows rooftop greenery coverage can help cool down a major city while reducing energy demand.
Extensive greenery coverage on building rooftops could significantly reduce temperatures at the city scale and decrease energy costs, according to a new study.
The research, led by Indira Adilkhanova and Professor Geun Young Yun from Kyung Hee University and co-authored by UNSW Sydney Scientia Professor Mattheos (Mat) Santamouris, found that green roofs could cool South Korea’s capital city by around 1°C during summer and slash the energy demand associated with cooling by almost 8 per cent under maximum coverage.
The study, published in Nature Cities, is the first to analyse the transformative effect of green roofs on urban-scale energy consumption and climate conditions and could provide a template for modelling their potential in other cities worldwide.
