In France a new law has been passed to secure that every building constructed for commercial purposes has either green roofs or solar panels in their top roofs.
This initiative helps to build up concern about environmental friendly construction together with the promotion of the already well known solar panels and the not that well known green roofs.
Solar panels would help to provide energy to the building activities and green roofs play an important role as well. Thanks to green roofs the isolation of the buildings improves so that more energy is saved in terms of heating and air conditioning.
Moreover, green roofs can help to reduce water run-off during rainstorms, they improve the urban landscape and provide the possibility to have a garden with agriculture.
A big step forward to improve life quality in urban areas, sustainability and reduce energy costs.
