Abstract
In today’s city environments, extreme weather conditions are a fact of
life. Amsterdam, Mumbai, Nairobi or Sydney… climate change issues
need to be tackled all around the world.
In the last couple of decades, Amsterdam has dealt with larger
amounts of rainwater, severe heat stress and a decreased biodiversity.
In order to strengthen urban resilience to climate change, blue-green
(BG) roofs are increasingly being introduced. BG roofs place
an additional water layer underneath the green layer. The idea is that
these roofs reduce runoff after rainfall by retaining precipitation and
mitigate heat stress, caused by increased evapotranspiration (the sum
of evaporation from the land surface and transpiration from plants)
and a higher albedo effect (the ability of surfaces to reflect sunlight).
