sustainability Article Green Roof for Stormwater Management in a Highly Urbanized Area: The Case of Seoul, Korea Muhammad Shafique 1,2, Reeho Kim 1,2,* and Kwon Kyung-Ho 3 1 Department of Smart City and Construction Engineering, Korea Institute of Civil Engineering and Building Technology, University of Science & Technology (UST), 217, Gajeong-ro, Yuseong-gu, Daejeon 34113, Korea; shafi[email protected] 2 Environmental & Plant Engineering Research Institute, Korea Institute of Civil Engineering and Building Technology, 83, Goyangdae-ro, Ilsanseo-gu, Goyang-si, Gyeonggi-do 10223, Korea 3 Urban Water Cycle Research Center, Korea Institute of Safe Drinking Water Research, Anyang si, Gyeonggi-do 14059, Korea; [email protected] * Correspondence: [email protected]; Tel.: +82-31-9100-291 Received: 26 December 2017; Accepted: 21 February 2018; Published: 26 February 2018 Abstract: Urbanization changes natural pervious surfaces to hard, impervious surfaces such as roads, buildings and roofs. These modifications significantly affect the natural hydrologic cycle by increasing stormwater runoff rates and volume. Under these circumstances, green roofs offer multiple benefits including on-site stormwater management that mimics the natural hydrologic conditions in an urban area. It can retain a large amount of rainwater for a longer time and delay the peak discharge. However, there is very limited research that has been carried out on the retrofitted green roof for stormwater management for South Korean conditions. This study has investigated the performance of retrofitted green roofs for stormwater management in a highly urbanized area of Seoul, the capital city of Korea. In this study, various storm events were monitored and the research results were analyzed to check the performance of the green roof with controlling the runoff in urban areas. -

Green Architecture and Water Reuse: Examples from Different Countries
Green architecture and water reuse: examples from different countries This paper shows different examples from different countries (Italy, India, Tanzania) of green architectural solutions (green wall, green roof, roof wetland) in which water (rain and treated greywater) are reused as a resource, in order to reduce the use of drinking water for activities not needing a high quality of water. Authors: Fabio Masi, Anacleto Rizzo, Riccardo Bresciani Abstract Water is a valuable resource which should be better managed to develop a sustainable future. Green architecture is starting to be largely applied, principally for aesthetic improvement of urban centres. However, green architectural solutions provide different additional benefits, among which the reuse of rain and treated grey water. Hence, green architecture can be also viewed as an option to limit the waste of drinking water for applications where the required quality can be lower. In this paper we report the application of three different green architectural solutions in which rain and treated grey water are reused (roof wetland, green roof, and green wall) in three different countries (Tanzania, Italy, and India). Technical data: Roof constructed wetland (Tanzania): • Greywater reused for irrigation • Greywater consumption of max 4 m3 per day • Sewer network for greywater and blackwater segregation • Two-chamber tank (2 m3) as pre-treatment • Pumping station (1.1 kW power, 30 l/min) to feed CW on the roof • Horizontal flow constructed wetland (23 m2, HRT 0.8 d) for greywater treatment -

Conceptual Green Infrastructure Design for the Blake Street Transit
2012 GREEN INFRASTRUCTURE TECHNICAL ASSISTANCE PROGRAM Urban Land Conservancy Denver, Colorado Conceptual Green Infrastructure Design for the Blake Street Transit-Oriented Development Site, City of Denver AUGUST 2013 Photo: Denver Housing Authority, Park Avenue Development EPA 830-R-13-002 About the Green Infrastructure Technical Assistance Program Stormwater runoff is a major cause of water pollution in urban areas. When rain falls in undeveloped areas, the water is absorbed and filtered by soil and plants. When rain falls on our roofs, streets, and parking lots, however, the water cannot soak into the ground. In most urban areas, stormwater is drained through engineered collection systems and discharged into nearby waterbodies. The stormwater carries trash, bacteria, heavy metals, and other pollutants from the urban landscape, polluting the receiving waters. Higher flows also can cause erosion and flooding in urban streams, damaging habitat, property, and infrastructure. Green infrastructure uses vegetation, soils, and natural processes to manage water and create healthier urban environments. At the scale of a city or county, green infrastructure refers to the patchwork of natural areas that provides habitat, flood protection, cleaner air, and cleaner water. At the scale of a neighborhood or site, green infrastructure refers to stormwater management systems that mimic nature by soaking up and storing water. These neighborhood or site-scale green infrastructure approaches are often referred to as low impact development. EPA encourages the use of green infrastructure to help manage stormwater runoff. In April 2011, EPA renewed its commitment to green infrastructure with the release of the Strategic Agenda to Protect Waters and Build More Livable Communities through Green Infrastructure. -

1 2 3 4 Intended users: City and County public works Young engineers Developers Public officials and other non-engineers The Decision Tree distills information from many manuals and sources into one spot, and provides convenient documentation for how/why decisions are made on a project-by-project basis. Intended for use with projects for which there is no regional stormwater facility available. 5 BMP functions that may be required: -Sediment control -Nutrient removal -Volume reduction -Peak discharge rate control -Channel protection 6 7 Stormwater ponds are typically installed as an end-of-pipe BMP at the downstream end of a trunk storm sewer system or of a treatment train. Wet extended detention basins are the only type of pond that complies with the NPDES Permit. - Dry detention ponds are ones in which the outlet elevation matches or is slightly below that of the inlet elevation. All runoff that enters the pond is consider to leave the pond, but the outlet is restricted to temporarily store the runoff prior to discharge. There is no sediment storage, and sediment that was previously deposited often is carried downstream with larger storm events. Therefore, dry detention ponds provide rate control but no water quality benefits. - FtlFrequently, unlined wet d et enti on pon ds can dtbttdry out between storm even tifthts if they are constructed in sandy soil due to infiltration. These may still be considered to provide water quality benefits as the runoff has to pond up to a certain depth before it can discharge through the outlet pipe, allowing for sedimentation. -
Green Roofs the Basics
Green Roofs The Basics Green roofs, or living roofs, are vegetated rooftop systems that reduce stormwater runoff by 50-60% and can triple the life expectancy of a roof. They can be installed on just about any rooftop, but require that the structure be able to withstand extra weight. Green roofs are categorized into two types, extensive and intensive. Extensive systems are thinner, with a layer of growing media that is 6” or less. Intensive roofs have a thicker growing media layer and may include trees or rooftop meadows. Due to the weight associated with intensive rooftops, they are typically only installed in new construction projects. Blue Water Baltimore wants to help you make a difference. This document provides a brief overview of green roofs and helps you complete the Project Approval Form for the Water Audit Program. Additional resources are available at www.bluewaterbaltimore.org/water-audit- resource/. Why Should I Install a Green Roof? What Does it Cost? Cost per square foot typically Extend the life of your roof ranges from $15-30 per square Improve the view from overlooking windows foot at the residential scale. If Minimize stormwater runoff the roof needs to be reinforced, the cost will be higher. Green roofs are not for everyone. A rain garden or conservation landscaping may not sound as exciting, but these are much more affordable ways to reduce stormwater runoff. When you register for the Water Audit Program, a Blue Water Baltimore staff member will conduct a site visit to assess your property. We will help you determine if a green roof is a good option for you. -
Ecoroof Stormwater Monitoring
STORMWATER MONITORING TWO ECOROOFS IN PORTLAND, OREGON, USA Doug Hutchinson, Peter Abrams, Ryan Retzlaff, Tom Liptan City of Portland, Bureau of Environmental Services Abstract Ecoroofs, long used in Europe to reduce stormwater runoff from rooftops, are beginning to be installed in North America. When the City of Portland, Bureau of Environmental Services (BES) began considering ecoroofs for stormwater management, no applicable performance data could be located. To generate region-specific data, BES initiated a monitoring project of an apartment building vegetated with two different ecoroofs. After over two years of water quality monitoring and over a year of flow monitoring, some impressive performance has been measured. Precipitation retention has been calculated at 69% for the 4-5 inch ecoroof substrate section and nearly all of the rainfall is absorbed during dry period storm events. Stormwater detention and peak intensity attenuation has also been impressive even when the roof was saturated during winter months. Some water quality benefits have proven more difficult to quantify but important water quality lessons have been learned. In situations where a receiving water system may be sensitive to certain pollutants, substrate composition will be an important consideration in the ecoroof design. Our work to date has proven that ecoroofs can be an effective urban stormwater management tool. The next major endeavor will be to apply this information to system modeling efforts to determine hydrologic and hydraulic infrastructure and stream benefits that may be achieved. This information is also expected to assist bureau managers, planners, engineers and elected officials with policy decisions, such as zoning density bonuses, infrastructure designs, drainage fee discounts, and code compliance. -

From Garden City to City in a Garden (Case Study: Shiraz City As a „‟Permaculture‟‟ Model in Iran)
Fattahi, S/Bazrkar, M From Garden to Garden 49th ISOCARP Congress 2013 From Garden City to City in a Garden (Case Study: Shiraz City as a „‟Permaculture‟‟ Model in Iran) Sara FATTAHI, Apadana Institute of Art and Architecture, Iran Mojtaba BAZRKAR, MAF Hypermarkets, Iran 1. City Developing or Garden creating? Human face many challenges related to the health and well being. Many of these challenges arise as the direct consequence of dense urban environments. Industry, automobiles, and impermeable concrete and asphalt surfaces combine to negatively impact upon the air and water quality, while climate change serves to exacerbate the urban heat island effect through global warming. To help alleviate the environmental problems encountered with dense urban habitation and to encourage sustainable development, governments and non-profit agencies worldwide are working toward creating laws, establishing standards, and funding incentives to promote best practices in development. Rooftop gardens are an excellent example of incorporating passive, eco-friendly technology into new or existing development. Rooftop gardens help mitigate the negative impacts of cities on the environment by: conserving energy and water, improving air and water quality, assisting in storm water management, absorbing solar radiation, becoming a source of local food production, providing habitat restoration, and creating natural retreats. Many cities have a lot of „lost‟, green space that can help them to communicate with nature. Good weather that can help them breeze better. At least, better life through developing the city. As our population grows, we will have to make a greater effort to ensure that we continue to make space for greenery and our natural heritage.
