Roof problems, especially roof leaks, not only disrupt building operations, but can also contribute to the occurrence of severe internal Indoor Air Quality (IAQ) problems (Oliver 1997; Rivin 2001; Haverinen, Vahteristo et al. 2003). One of the well-accepted causes of roof leaks is the lack of roof maintenance (Lounis, Vanier et al. 1998a). The out-of-sight, out-of-mind nature of a roof’s locati...

Performance of vegetated roofs are investigated in terms of their expected benefits for the building and the urban environment, due to their recognised energy and water management potential scores. A review of related worldwide experiences is reported for comparison purposes. The investigation is here performed within the specific climatic context of the Mediterranean region. Full-scale experim...

The benefits of rooftop greenery systems (such as energy savings, reduction of greenhouse gas emission for mitigating climate change and maintaining sustainable development, indoor temperature control etc.) in buildings are well recognized, however there remains very little research conducted for quantifying the benefits in subtropical climates such as in Australia. This study mainly focuses on...

BACKGROUND Green roofs perform ecosystem services such as summer roof temperature reduction and stormwater capture that directly contribute to lower building energy use and potential economic savings. These services are in turn related to ecosystem functions performed by the vegetation layer such as radiation reflection and transpiration, but little work has examined the role of plant species c...

extended abstract 1. introduction the important roles played by green space are the social, economic, cultural and environmental aspects of sustainable development. thus, the quality and quantity of green space should be appropriate to the physical size of the city and the needs of society and also it should be developed according to the ecological conditions of the city and its future developm...

Recent studies have highlighted the ecological, economic and social benefits assured by green roof technology to urban areas. However, green roofs are very hostile environments for plant growth because of shallow substrate depths, high temperatures and irradiance and wind exposure. This study provides experimental evidence for the importance of accurate selection of plant species and substrates...

Green roof technology is recognized for mitigating stormwater runoff and energy consumption. Methods to overcome the cost gap between green roofs and conventional roofs were recently quantified by incorporating air quality benefits. This study investigates the impact of scaling on these benefits at the city-wide scale using Washington, DC as a test bed because of the proposed targets in the 20-...

A roof provides protection to be safe from direct sunlight. From the shelter, shadow alone is not expected. Durability, sustainability, less life cycle cost, and low maintenance cost are expected from a selected roof. The world has a thirst to have a best roof. No roof will fulfil the requirement of humanity since the climatic conditions are different. Hence the roof should be selected accordin...

Green roof ecosystems are constructed to provide services such as stormwater retention and urban temperature reductions. Green roofs with shallow growing media represent stressful conditions for plant survival, thus plants that survive and grow are important for maximizing economic and ecological benefits. While field trials are essential for selecting appropriate green roof plants, we wanted t...
