Quick answer：Roof greening refers to the practice of creating green spaces on rooftops, which can include the installation of vegetation and soil. Business cases for roof greening can include benefits such as improved energy efficiency, reduced urban heat island effect, increased biodiversity, and enhanced property value. Examples might include commercial buildings with extensive rooftop gardens, green roofs integrated into new construction projects, or existing buildings retrofitting with green roofs. These cases demonstrate the potential economic, environmental, and social benefits of roof greening initiatives.
