Green roofs deliver critical protection from ‘severe urban heating’
In January, Victoria councillors unanimously voted to explore ways to help residents install green roofs and rooftop solar, reports Capital Daily, addressing barriers like zoning and floor-space-ratio bylaws.
The B.C. capital’s move comes 15 years after Toronto became the first city in North America to pass a bylaw requiring all new construction with a footprint exceeding 2,000 square metres to incorporate a green roof.
The decision comes just weeks after Somerville, Massachusetts, passed a law that will require all new buildings and major rebuilds with flat roofs to ensure that 80% of roof space is green.

Dr. Mattheos Santamouris: Leading the Charge in Urban Cooling Innovations at UNSW Sydney
Over a rigorous three-year period marked by the challenges of the COVID-19 pandemic, Professor Santamouris and his team undertook an ambitious project to address the extreme heat in Riyadh, where temperatures can soar to an incredible 45°C. Their comprehensive research explored the impact of ‘super cool’ building materials, the introduction of green spaces, and the application of energy-efficient retrofits, leading to a strategy that could reduce urban temperatures by as much as 5°C. This achievement marks a pivotal step in improving urban living standards, cutting down on energy usage, and enhancing the quality of life for residents.

Green roofs can cool cities and save energy: modelling
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.
