A roof covered with vegetation designed for its aesthetic value and to optimize energy conservation.
Green roof technology definition.
Green roofs last longer than conventional roofs reduce energy costs with natural insulation create peaceful retreats for people and animals and absorb storm water potentially lessening the need for complex and expensive drainage systems.
What is a green roof.
