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.
Interesting that they note that the installation and upkeep are expensive. I wonder if they’ve factored the upkeep into the energy expenditure. Flat roofing is far worse than a pitched room for needing replacement etc.
Basically, it sounds good, but the research needs to consider the full lifecycle of these projects.
Also looks great.
Buuuut it’s expensive and needs constant maintenance. It’s also a greater risk, there have been cases of trees being blown off of buildings like this, although if properly anchored with shitloads of netting this shouldn’t be an issue.
I do wonder if it’s more practical to just put solar panels there though
They work great together. Bifacial PV panels let enough light through for growing, and make excellent vertical edge barriers.
