EcoCities is an interdisciplinary project which researches the potential of green roofs and facades as a source of a ecosystem services in cities. Three research groups of the University of Antwerp are engaged in this project. PLECO (Prof. Ivan Janssens) researches carbon sequestration in green roofs. ENDEMIC (Prof. Roeland Samson) aims to better understand the potential of green roofs and facades for air purification whereas ECOBE (prof. Patrick Meire, dr. Jan Staes) quantifies the ecosystem services. The project is being coordinated by UHasselt.
