Energy savings in buildings or UHI mitigation? Comparison between green roofs and cool roofs
The intensification of the Urban Heat Island effect (UHI) is a problem that involves several fields, and new adequate solutions are required to mitigate its amplitude. The construction sector is strictly related with this phenomenon; in particular, roofs are the envelope components subject to the highest solar irradiance, hence any mitigation strategy should start from them and involve their ap...
متن کاملDo green roofs provide habitat for bats in urban areas ?
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...
متن کاملThe effectiveness of cool and green roofs as urban heat island mitigation strategies
Mitigation of the urban heat island (UHI) effect at the city-scale is investigated using the Weather Research and Forecasting (WRF) model in conjunction with the Princeton Urban Canopy Model (PUCM). Specifically, the cooling impacts of green roof and cool (white/highalbedo) roof strategies over the Baltimore-Washington metropolitan area during a heat wave period (7 June–10 June 2008) are assess...
متن کاملCost-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...
متن کاملGreen Roofs in the Tropics Conserve Energy
Background: Concrete buildings on Guam are exceptionally strong but also accumulate large amounts of heat. In the tropical environment of Guam, where 24 h average temperature ranges from 28 to 29oC year round, air conditioning is used every day and continuously. Concrete roofs are often painted light colors, which make them more reflective and accumulate less heat. They are also suitable for es...
