European project to turn roofs into greenhouses

When agriculture meets construction, the cities of tomorrow take shape and with them, urban innovations emerge. A real trend in recent years, Urban Farming is nowadays not only an alternative to traditional modes of production and consumption, but above all an innovative solution for reinventing cities.

It is in this dynamic that the European GROOF project - Greenhouses to Reduce CO2 on RooFs - was born. Launched in 2017 and supported by the INTERREG NWE programme, it is an innovative cross-sectoral approach to reduce CO2 emissions from the construction and agricultural sectors by combining energy sharing and local food production. Thus redesigned, buildings then become real technological platforms with new functionalities, capable not only of producing and/or storing energy for example, but also of producing vegetables.

While focusing on reducing energy and environmental impact, the GROOF project promotes the implementation of greenhouses on the roofs of buildings and facilitates their emergence on the market by demonstrating and disseminating good practices to construction and agricultural stakeholders, which promote the development of profitable and functional social business models. For example, 4 pilot greenhouse projects are currently under construction in Luxembourg, Belgium, Germany and France. But GROOF does not stop there and is launching a new call for projects.
