Modeling shows green roofs can cool cities and save energy::Extensive greenery
coverage on building rooftops could significantly reduce temperatures at the
city scale and decrease energy costs, according to a new study.
It’s a cross-post from lemmy.world. Hope I’m doing it right.
The trouble is that it only really works for new construction, older buildings are not engineered to handle the extra weight on the roof.
Yeah. There was an incident in the university where I studied that the whole roof collapsed. https://hongkongfp.com/2016/06/10/city-university-may-sue-contractor-rooftop-collapse-investigation-report-released/
