Thermal Performance of Extensive Green Roofs in Cold Climates

Green roof is a specialized roofing system that supports vegetation growth on rooftops. This technology is rapidly gaining popularity in North America as a sustainable design option. Green roofs offer multiple benefits to urban areas such as reduction of heating/cooling needs for the building, urban heat island and stormwater runoff for the region. In this study, the performance of two extensiv...

Green Roofs as Urban Ecosystems: Ecological Structures, Functions, and Services

Cost-Effectiveness of Green Roofs

Life-cycle assessment was used to evaluate the widespread installation of green roofs in a typical urban mixed-use neighborhood. Market prices of materials, construction, energy conservation, storm-water management, and greenhouse gas GHG emission reductions were used to evaluate private and social costs and benefits. Results suggest green roofs are currently not cost effective on a private cos...
