Energy could be saved by creating green roofs and walls covered with plant life such as grass, moss or creepers. Scientists have found green surfaces can reduce the need for air conditioning on hot days by causing local temperatures to drop. Research was carried out by Eleftheria Alexandri and Phil Jones at the Welsh School of Architecture in the UK. They used computer models to find out how temperatures can vary when buildings are covered in greenery.
