This study investigates people's preconceptions of green roofs and their visual preference for different green roof design alternatives in relation to behavioral, social and demographical variables. The investigation was performed as a visual preference study using digital images created to represent eight different alternatives: gravel roof, extensive green roof with Sedums not in flower, exte...

The need to prepare cities for climate change adaptation requests the urban modeller community to implement sustainable adaptation strategies within their models to be tested against specific city morphologies and scenarios. Greening city roofs is part of these strategies. In this context, the GREENROOF module for TEB (town energy balance) has been developed to model the interactions between bu...

Sustainability trends for buildings require new construction systems to foster energy efficiency and environmentally friendly buildings. Green roofs are interesting construction systems because they provide both aesthetic and environmental benefits. This paper continues a long-term research in order to evaluate and improve the thermal behaviour and sustainability of extensive green roofs. Simul...

Title of Document: INVESTIGATING CRUMB RUBBER AMENDMENTS FOR EXTENSIVE GREEN ROOF SUBSTRATES Sonia Lorelly Solano Torres, MS, 2010 Directed By: John D. Lea-Cox, PhD. Chair, Plant Sciences and Landscape Architecture Department Extensive green roof systems can mitigate urban stormwater by capturing rainfall and reducing runoff volume. Green roof substrates, often made from expanded shales, slates...

We assessed the total energy required to manufacture, install and maintain an extensive, sedumplanted green roof over its assumed life of 20 years in the Mid-Atlantic region of the U.S. using the method of emergy analysis. We estimated its environmental benefits as the sum of summer electricity savings due to cooler building temperatures, primary production of biomass and reduction in intensity...

Urban land area in the United States is projected to increase to 8.1% of total land area by the year 2050. These human-dominated environments create conditions that degrade both terrestrial and aquatic ecosystems. If cities are to reduce their environmental impact, innovative practices must be developed that replace ecosystem services lost during the urbanization process. This study evaluated t...

Along with the strong movement towards sustainable urban environments, there is an increasing use of green roof systems, including the semi-extensive green roofs, which are composed of lightweight layers of freedraining material that support low-growing, tough, and drought-resistant vegetation. Various kinds of green roof systems are also used at street levels, on the top of underground car par...

To educate the Purdue community and general public about the environmental benefits of green roofs, the Boiler Green Initiative (BGI) installed Tippecanoe County’s first green roof on Purdue’s campus in May 2009. The extensive green roof is approximately 165 m and consists of vegetation and pavers to make the space an aesthetically pleasing, usable environment. A monitoring system records surfa...
