Green roofs or solar panels are now required on all new commercial buildings in the country of France. This is great because now buildings can have either a zero energy impact or contribute to their local environment.
Rooftops on new buildings built in commercial zones in France must either be partially covered in plants or solar panels, under a law approved on Thursday.
Green roofs have an isolating effect, helping reduce the amount of energy needed to heat a building in winter and cool it in summer
