Many vegetable gardens use small, flat greenhouses to grow crops. Of course, these could also be used on rooftops. The effects of the wind and rain are often even more intense there than in gardens. Building on the idea of multifunctional rooftop use, translucent solar panels could also be used instead of ordinary glass. That way, young crops are protected against bright sunlight and energy can be generated at the same time. This greenhouse was built by Ontregelmaat.
