Green 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...
متن کاملEnergy 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 کاملHydroponics Roofs for Saving Energy of Green Schools in the Cold and Dry climate of Iran: A Comparative Study between Two Broad and Modular Hydroponic Green Roofs
Green schools are a new type of school, in which the use of renewable energy is less than that of conventional schools. In this regard, nowadays, adding green layers to the roof of schools, in addition to increasing the Students' communication with nature, energy saving has improved in these spaces. However, to improve energy saving yield, the priority of these types of roofs in different clima...

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...
