Extensive Green Roofs in Mississippi: An Evaluation of Stormwater Retention under Local Climatic Conditions

Anders, Robert Mack 12 May 2012 (has links)
Green roofs are increasingly being used in the United States to mitigate the negative effects of impervious surfaces on aquatic ecosystems. Though performance of these systems varies with climate, little research has been conducted in the Southeastern U.S., and no prior research has been conducted in Mississippi. An experiment was conducted to determine the effect of soil depth and roof slope on the stormwater retention of green roofs in Mississippi’s hot, humid climate. Simulated roof platforms were constructed to investigate two soil depths and two slopes, each replicated three times and planted with four species of Sedum. The green roof platforms significantly reduced runoff depth when compared with total rainfall depth. Soil depth and slope both significantly affected retention, with higher retention seen with increasing soil depth and lower retention seen with increasing slope. These results indicate that green roofs can be an effective tool to reduce runoff in Mississippi.

Městská knihovna v Přerově / City Library of Přerov

Ptačin, Ján January 2012 (has links)
The new public library building needs to meet a lot of diverse demands. It has to be developed in conjunction with librarian's needs, it has to react on existing urban conditions and it needs to be self-defining and future oriented, so it will be able to cope with radical changes in the communications we experience nowadays. Our proposition is a reaction to the impulses of the site combined with our view of what a new library should represent. It is: communication, interaction, inspiration. We try to eliminate negative aspects of the selected site and on the other hand, use and develop existing potential. The building tries to terminate the big crossroads next to the site and on the contrary to create a nice quiet public space with the church. It also wants to be a new landmark and icon of the town. The solution we found is based on two main principles. A fence. And a hill. Fence as a guard and prevention from crossroads, as a closure of the urban block and public space with green and church building inside, as a boarder with the industrial part of the town, as a show-off wall, a allure to the world of wisdom and quiet public space behind... It is represented by double glass facade along the border of the site. Hill as an activator of the site, as an icon and a brand of the place, as a second hill in whole town, as an island and oasis, as a place for sport, play, as an open public reading room, as a natural amphitheatre... It consists of a simple green roof raising from the church towards the sky, covering the library buiding.

GROWING IN CITIES : rooftop urban agriculture for sustainable cities

Toporova, Jelizaveta January 2018 (has links)
The thesis takes into notice a rare case of integration of rooftop urban agriculture into sustainable development of urban areas. The current situation shows that the development of rooftop urban agriculture has not been adequately studied. This master thesis aims to enhance the understanding regarding planning opportunities and challenges for integration of rooftop urban farming in urban design and sustainable urban development with a focus on environmental benefits of its implementation. Furthermore, the thesis brings up a conceptual design programme «Malmö FIVE» that shows one of the ways how architects and urban planners could inspire city developers and municipalities to explore the ways of the redevelopment of the existing unused urban spaces into the new resilient environments.  The thesis based on a combination of literature review, analysis of planning materials, site visits, conducting interviews, discussions and attending seminars and lectures to answer the research questions. The research identified multiple challenges that can be encountered in the process of implementation of rooftop urban agriculture. The findings determined the importance of rooftop urban agriculture being approached from the strategic sustainability perspective to value its potential fully. Rooftop urban agriculture can provide significant environmental values thus have an essential role in the sustainable development of urban areas.

The fire resistance of lowgrowing plants : Assessment of the fire resistance of lowgrowing plants used in roofing applications

Serrano Silva, Heidy January 2024 (has links)
Green infrastructure, including green roofs and urban vegetation, offers numerous benefits but also presents fire safety risks. Currently, there are no specific regulations in Sweden addressing the fire safety risks associated with green roofs.  Therefore, the aim of this study is to investigate the fire resistance of low-growing plants and their potential to mitigate these fire safety risks. A total of ten different plant types are analyzed, with four classified as fire-resistant and four as fire-prone based on their characteristics. The study also incorporates a 17-day dry period to assess the impact of moisture on the ignitability of the plants. By using a cone calorimeter, the plants' fire safety, their contribution to fires, and their ability to produce carbon monoxide are analyzed. For an overall assessment of fire safety, the Fire Growth Rate (FIGRA) and Fire performance index (FPI) are calculated for each plant.  The conclusions reveal that plants like Sempervivum species and chives exhibit superior moisture retention and fire safety characteristics, including low heat release rates, minimal smoke production, and effective heat capacity.  The disparity between FPI and FIGRA values indicates better flame-retardant abilities of the material, where Sempervivum species, chives, and Saxifraga Arendsii show the best values. These findings emphasize the significance of meticulous plant selection and maintenance to mitigate fire risks in both natural and urban environments. It’s essential to acknowledge that even fire-resistant plants necessitate regular maintenance, such as the removal of dead material and watering during extended dry periods, as fire resistance does not equate to fireproof.  Proposed future work entails a deeper exploration of the chemical properties and morphology of the plants to enhance our understanding of their fire resistance mechanisms. Additionally, compiling data on recommended plants for green roof installations from a fire safety perspective could aid in urban planning and vegetation management. / Grön infrastruktur, inklusive gröna tak och stadsväxtlighet, erbjuder många fördelar men innebär också brandsäkerhetsrisker. För närvarande finns det inga specifika regler i Sverige som behandlar brandsäkerhetsriskerna med gröna tak.  Därför är syftet med denna studie att undersöka brandmotståndet hos lågväxande växter och deras potential att minska dessa brandsäkerhetsrisker. Totalt analyseras tio olika växttyper, varav fyra klassificeras som brandbeständiga och fyra som brandbenägna baserat på deras egenskaper. Studien inkluderar även en simulering av en 17 dagar lång torrperiod för att bedöma fuktighetens påverkan på växternas antändbarhet. Genom användning av en konkalorimeter analyseras växternas brandsäkerhet, deras bidrag till bränder och deras förmåga att producera kolmonoxid. För en övergripande bedömning av brandsäkerheten beräknas brandspridningshastighet (FIGRA) och brandskyddsindex (FPI) för varje växt. Slutsatserna avslöjar att växter som Sempervivum-arter och gräslök uppvisar överlägsen förmågan att behålla fukt och brandsäkerhetsegenskaper, inklusive låga värden av värmeavgivningshastighet, minimal rökproduktion och effektiv värmekapacitet.   Skillnaderna mellan FPI- och FIGRA-värdena indikerar bättre flamskyddande förmåga hos materialet, där Sempervivum-arter, gräslök och Saxifraga Arendsii visar de bästa värdena. Dessa resultat understryker vikten av noggrann växtval och underhåll för att minska brandriskerna både i naturliga och urbana miljöer. Det är viktigt att förstå att även brandbeständiga växter kräver regelbunden skötsel, såsom borttagning av dött material och bevattning under långa torrperioder, eftersom brandbeständighet inte innebär att något är helt brandsäkert.   Föreslaget framtida arbete innefattar en djupare utforskning av växternas kemiska egenskaper och morfologi för att förbättra vår förståelse av deras brandsäkerhetsmekanismer. Dessutom kan sammanställning av data om rekommenderade växter för gröna takinstallationer utifrån ett brandsäkerhetsperspektiv underlätta för stadsplanering och vegetationshantering.

Life Cycle Cost Analysis Framework of Green Features in Buildings

Alborzfard, Nakisa 05 January 2011 (has links)
Sustainability has been heightened to a new level of importance, due to the current global race for commodities and conservation of our environment. Sustainable Buildings are of particular interest since buildings are significant contributors to consumption of resources. Since the inception of the United States Green Building Council (USGBC) in 1993, USGBC has played a key role in providing guidance to the design and construction community in building“green" structures. The Leadership in Energy and Environmental Design (LEED) rating system is an industry accepted standard for the design/construction and measurement of green buildings. Although USGBC provides guidance on performance measurement, a streamlined process of performance tracking and measurement has not been formalized. This research focuses on identifying vital areas of required tracking and measurement; to allow for a systematic analysis of costs and benefits, over the life of sustainable buildings. A case-study based on the recently designed and constructed East Hall LEED-Gold Certified, dormitory building at Worcester Polytechnic Institute (WPI), was undertaken to create and assess a life cycle costs analysis framework. This research is aimed at understanding what the costs of building green at WPI truly are. Life Cycle Cost Analyses of the mechanical, electrical, plumbing and roof components were evaluated to generate percent savings or percent added cost. This research reviewed the various green and non-green costs of construction, consumption, and operations and maintenance costs providing a comparative analysis to leading researchers in the field of costs and benefits of building green.
