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...

The effects of climate change in coastal semi-arid and arid Mediterranean areas are intense. Green roofs planted with native plant species that able to withstand saline conditions can contribute supporting climate-change adaptation preservation wetlands, enhancing the character local landscapes reducing disaster risk. Considering limited availability water resources, there is increasing interes...

• We develop a simple mathematical model to estimate the energy stored in green roof and provide analytical solutions. The effect of different key parameters on both surface temperature is discussed. A typical significantly cooler stores less than concrete even with high albedo coating. Evaporation few millimeters per day leads threefold reduction compared roofs. developed. Analytical solutions...

As the world population continues to increase, with more than 50 percent of people now residing within cities, remaining natural and semi-natural habitats within urban areas play an increasingly important role for people and wildlife (Mortberg and Wallentinus, 2000; Benedict and McMahon, 2002; Jim, 2004; Town and Country Planning Association, 2004; Bierwagen, 2007; Gill et al., 2007; Tratalos e...

The installation of green roofs, defined here as rooftops with a shallow soil cover and extensive vegetation, has been proposed as a possible measure to mitigate the loss of green space caused by the steady growth of cities. However, the effectiveness of green roofs in supporting arthropod communities, and the extent to which they facilitate connectivity of these communities within the urban en...
