With so much available roof space in cities, Green roofs represent opportunities with significant social, economic and environmental benefits. Green roofing is commonly associated with several types of vegetative plantings. The term green roofing is also used to indicate roofs that use some form of “green” technology, such as a cool roof (white or solar reflective), sustainable construction assemblies or a roof with solar photovoltaic panels.Cool roofs reduce both building cooling loads and the urban heat island effect. Solar paneled installations minimize our dependency on non-renewable energy sources and also reduce the negative effects of carbon-based emissions. Sustainable construction assemblies significantly reduce the impact on landfills and optimize the life cycle performance.
