2. 1. Modeling stormwater transport through unsaturated green roof substrates

   Author : Kaj Pettersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; Lattice Boltzmann; porous media; CFD; saturation; multiphase; Green roofs;

   Abstract : In recent decades there has been an increase in research regarding green roofs and similar technologies. This increased interest is driven by the requirements of urban development and its effects both on humans and the environment. READ MORE

4. 2. Extensive green roofs in Porto Alegre, Brazil : Effect on indoor thermal comfort in residential buildings

   Author : Lisandra Fachinello Krebs; Institutionen för arkitektur och byggd miljö; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Computer simulations; Extensive green roofs; Housing projects; Indoor thermal comfort; Leaf area index; Microclimate; Social housing; Sustainability; Thermal comfort;

   Abstract : Brazil had a significant quantitative housing deficit of 7.7 million residences in 2015, especially in low-income housing. Traditionally, these projects have low levels of thermal insulation which can result in discomfort caused by warmth or cold. The residential sector is responsible for a significant part of the energy use in Brazil. READ MORE

5. 3. Beneficial Use of Stormwater - Opportunities for urban renewal and water conservation

   Author : Edgar Villarreal-Gonzalez; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; offshore technology; hydraulic engineering; Civil engineering; water conservation; rainwater collection; Best Management Practices; Urban stormwater; green-roofs; open drainage systems;

   Abstract : This thesis investigates the beneficial use of stormwater in Swedish urban environments. The focus has been on open stormwater systems for source control, as well as rainwater collection systems. To analyse the implementation of open stormwater systems, two case studies are presented: Augustenborg in Malmö and Bäckaslöv wetland in Växjö. READ MORE

6. 4. Hydrological modelling of green urban drainage systems : Advancing the understanding and management of uncertainties in data, model structure and objective functions

   Author : Ico Broekhuizen; Maria Viklander; Günther Leonhardt; Jörg Rieckermann; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

   Abstract : The use of green urban drainage systems such as green roofs, swales and pervious areas has in recent years become a popular option to reduce flood risk and water quality problems in a more sustainable way than with traditional pipe-based drainage systems. Computer models are valuable tools for the management of such systems. READ MORE

7. 5. Mitigation of urban storm water runoff through application of computational fluid dynamics

   Author : Kaj Pettersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microstructure; infiltration; Green roof; CFD; wind-driven rain; building facade.; lattice Boltzmann;

   Abstract : This thesis covers computational methods for improving the ability of green roofs to mitigate storm water runoff in urban environments. Roofs with living vegetation, known as green roofs, have been used for this purpose however quantification of their ability to slow and stop rainfall runoff has not been undertaken to a large degree.
