        Sustainable living is a greatly inspiring blog. If you are interested in living more sustainably, this blog has lots of great ideas. It’s simple but informative. Sometimes, it’s hard to know what you can do to help the environment. If this is you, then Sustainable Living is a great blog for you to check out. It’s amusing and informative.

I made this movie to help address the concern of ever increasing CO2 amounts in the atmosphere and how incorporating green infrastructure in cities is a key step in reducing Green House Gases...

A Few Types of Green Infrastructure and how they help 

Right-of-way Bioswales

      The word Bioswale is  used to describe a planted area that is used to collect rainwater. ROW Bioswales absorb storm water by the sandy soil in the top and stone layer on the bottom, and seeps into the ground through infiltration. The water is then taken up by the trees and plants and is then released into the air through the process of evapotranspiration. Bioswales help by collecting and managing stormwater, reducing CO2 into the atmosphere, and by controlling erosion. 

Storm water Greenstreets 

          Much like ROW bioswales, Storm water Greenstreets are planted areas designed to collect and manage stormwater runoff. They are generally constructed in the roadway and are bigger than ROW Bioswales with varying soil depths, lengths, and witdths.      

Permeable Paving 

        Not all green infrastructure has to involve plants. Permeable paving is made of a range of materials, such as porous concrete. This allows water to seep in between the paving materials and be absorbed into the ground. It can be used as a replacement for traditional impermeable concrete or asphalt. In addition to reducing runoff, this effectively traps suspended solids and filters pollutants from the water. 

 

Cisterns and Rain barrels 

        Cisterns and Rain barrels are a couple of the most basic types of green infrastructure. They Manage storm water run off and can help conserve fresh water by watering gardens. Cisterns are often larger than rain barrels and can be located underground, at ground level, or on an elevated stand. Rain barrels are connected to the downspout of a roof and capture the storm water for watering plants and other landscaping uses. 

Ecological Rooftops

                                                                  

Brenneisen, S. (2006, December). Space for Urban Wildlife: Designing Green Roofs as Habitats in Switzerland. Urban Habitats, Retrieved from http://www.urbanhabitats.org/

        Stephan Brenneisen’s research focusing on biodiversity of green roofs has led to a change in the construction law in Basel, Switzerland. Green roofs are required  on buildings with flat roofs and help is available to create different plant and animal habitats on green roofs. Studies done in Zurich, Switzerland have shown that natural soils can lead to a higher biodiversity through their sustainability for locally and regionally endangered species. For plant and animal species mobile enough to reach the roofs, extensive green roofs can provide a suitable habitat for them to live in. Green roofs can supply beneficial habitat functions such as a nesting location as well.

Chao, J. (2014, January 21). White, Green or Black Roofs? Berkeley Lab Report Compares Economic Payoffs. Berkely Lab, Retrieved from http://newscenter.lbl.gov/

             Julie Chao uses research compiled from Julian Sproul, Benjamin Mandel, Arthur Rosenfeld, and Man Pun Wan to compare Green, White, and Black Flat roofs. Rooftop gardens provide storm water management, help cool roofs’ surfaces, and help cities that struggle with sewage overflow.  Both white and green roofs both cool the building they are on as well as cooling the air in the city. Black roofs can pose a major health risk in cities with high temperatures in the summer. Julie Chao uses Arthur Rosenfeld’s research to show that both white roofs and green roofs can be used as an effective way to reduce energy costs and to address global warming.

Green, J. (2013, April 2). New Research: Parks Alleviate Brain Fatigue. The Dirt , Retrieved from http://dirt.asla.org

            Jared Green uses research from Gretchen Reynolds, Dr. Michael Posner, and Dr. Marc Berman, to show that living near green space in an urban environment can lower levels of Cortisol (a stress hormone) in their saliva. A study from Scotland shows that “brain fatigue” can be helped by walking a half-mile through a park. Green rooftops can be maintained just like a park to help alleviate brain fatigue and stress. Jared Green shows that having green space in cities is not only beneficial to the environment, but is also very important and beneficial to human health.

Green Roofs. (2008, June). EPA, Retrieved from http://www.epa.gov/

            Using the research from Baskaran, Kuhn, Adriaens, Clark, and Talbot, EPA has determined that although green roofs cost around $129,000 more than a conventional roof, over a lifetime they can save over $200,000. They can reduce heat islands in urban areas. Conventional roofs can be up to 90 degrees Fahrenheit warmer. EPA talks about how green roofs can reduce energy use, reduce greenhouse gas emissions, improve human health and comfort, and improve storm water management and water quality.

Klinkenborg, V. (2009, May). Up on the Roof. National Geographic, (Ice Baby), Retrieved from www.nationalgeographic.com/

        The author, Verlyn Klinkenborg, uses data from Stephan Brenneisen, a swiss scientist studying biodiversity on green rooftops, and from Maureen Connelly, a researcher of green roofs at the British Columbia Institute of Technology, to expand upon how green roofs benefit humans living in urban areas. Although the cost of having a green roof is more than a conventional roof, it is cheaper in the long run due to its energy saving ability. Verlyn Klinkenborg finds that, overall, exposure to green rooftops makes people feel happier based on their small contribution to their environmental footprint as well as working as insulation to help lower the heating and cooling costs of a building by 20%.

     When walking around most cities, what do you see? An artificial landscape built from a lot of concrete and asphalt (among other things) but not much green. Having so many impermeable surfaces creates copious amounts of polluted runoff that flows directly into receiving waterways. The application of green infrastructure into a city's planning is extremely important because it helps prevent pollution while simultaneously adding natural processes to an urban environment. Highways, parking lots, and rooftops have created the problem of contaminated runoff when there are storms and big rains. 

      Green Infrastructure helps solve urban problems by using natural processes. A few main components include:

• Storm water management 
• Climate adaption
• Less heat stress
• Higher biodiversity 
• Better air quality 
• Sustainable Energy Production
• Clean water and healthy soils
