Green Roofs How Do They Work? By: Ronlynn Lee

What about Green Roofs?

What is a green roof and what do they do you ask? A green roof is a system that an extension of the existing roof which involves high quality water proofing and root repellent system, a drainage system, filter cloth, a lightweight growing medium and plants. Green roof systems may be modular with the use of drainage layers, filter cloth, growing media and plants already prepared in movable, interlocking grids, or, each component of the system may be installed separately. Green roof develops into an green space on top of a human made structure. Green spaces are not planted in the ground, but could be below, or above grade.

Benefits of Green Roofs

There are many good reasons to build a green roof. Green roofs provide insulation of the layers of organic materials. That help keeps the temperature warm in the winter and cool in the summer. Green roofs also help cut down the energy use and cost. This could be an natural habitat for animals such as wild bees, butterflies, beetles and be an natural cycle of plants growth and self seeding. Green Roofs are very important instruments in preventing local flooding by storing the excess rain in the filtered and drained off with temporal delay.

The Costs of Green Roofs

Green Roofs are more expensive in cost than other roofing. Green Roofs cost $8 per square foot is a minimum but values around $12 to $24 per square foot are common. These amounts may amount to 5 to 10 times the cost of other traditional building. Other potential drawbacks are higher maintenance costs, restrictions involving climate and weather conditions, complex drain system and stronger roof beams in order to support the several green roof layers. Eve more costly repairs and fixings like finding and repairing leaks is more expensive and difficult.

THE IMPORTANCE WITH SUSTAINABLE ARGICULTURE.


Sustainable agriculture was addressed by Congress in the 1990 Farm Bill [Food, Agriculture, Conservation, and Trade Act of 1990 (FACTA), Public Law 101-624, Title XVI, Subtitle A, Section 1603 (Government Printing Office, Washington, DC, 1990) NAL Call # KF1692.A31 1990]. Under that law, “the term sustainable agriculture means an integrated system of plant and animal production practices having a site-specific application that will, over the long term:

satisfy human food and fiber needs
enhance environmental quality and the natural resource base upon which the agricultural economy depends
make the most efficient use of nonrenewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls
sustain the economic viability of farm operations
enhance the quality of life for farmers and society as a whole.”

Sustainable agriculture takes many forms, but at its core is a rejection of the industrial approach to food production developed during the 20th century. Although these changes have had many positive effects and reduced many risks in farming, there have also been significant costs.Prominent among these are topsoil depletion, groundwater contamination, the decline of family farms, continued neglect of the living and working conditions for farm laborers, increasing costs of production, and the disintegration of economic and social conditions in rural communities.

Deforestation: Why Should You Care?

Deforestation:
Why Should You Care?

By: Kanisha Smith-Heard

Losing It All.

Deforestation is the clearing of forests, and that's exactly whats going on right now and many people don't know how this is effecting them. Deforestation is clearing the Earth's forests on a huge scale. Resulting in having very little quality of land. Although forests still cover over 30 percent of the worlds land area, it also decreases the size of Panama each year. At the current rate, in a hundred years there will be no more rain forests due to deforestation.


What Are The Causes?

Forests are cut down for many reasons, such as things related to money and people that need to provide for their families. The biggest issue that has to do with deforestation is agriculture. Farmers cut down forests to make more room for planting crops or grazing livestock. They sometimes get rid of a few acres by burning and cutting down trees which is called "slash and burn" agriculture.


Who Does It Effect?

It effects everyone and everything! Creatures and wildlife will have no place to live if all the rain forests are gone. Humans too. From something as little as the spices that indulge food to life giving medicines we need our forests. 25 percent of medicines come from forests.The forest gives life to not just species but but they help extend the duration of human life. Forests also do something that you can do without thinking; BREATHING! Trees absorb carbon and other particles caused by pollution which improves the air that we all breathe.


What You Can Do.


So now we come down to the final question: What can you about deforestation?. Here are a few things you can do to help out.

Plant A Tree!That's obviously a way to combat deforestation. Plant a few in your neighborhood.

Go Paperless!Cut back on the paper you use each day.

Buy Recycled! Use paper with the highest percentage of recycling content. Buying a case of paper in lieu of virgin paper saves about one tree!


Together we can help fight deforestation.

Here's a link to tell you more about deforestation:

Effects of Globle Warming

To inform and educate the public concerning the health, economic, and aesthetic effects of air pollution and the technological and legal tools available for its control; to promote understanding of the role of government (national, state, and local) in the control of air pollution; and to stimulate voluntary and official efforts to clean the air." (Bylaws, 1967)

Over the last few years, the Council has implemented an aggressive program on Clean Air Act implementation consisting of government oversight, constituency building, and media outreach, to ensure that Pennsylvania is fully meeting its obligations under the Clean Air Act. Additionally, the Council, a strong advocate of strengthening the federal health standards for ground level ozone and fine particulate matter, is working with various stakeholders to seek innovative, cost-effective, and environmentally sound programs to address issues such as air pollution transport.

Want you can know about the desert

Did you know that the desert cover more then one fifth of the earth's land. Deserts are part of a wider classification of regions called dry land. It is just not dry and hot deserts there are also cold ones as well. The largest hot desert in the world is the northern Africa's Sahara. It reaches temperatures of 122 degrees Fahrenheit (50 degrees Celsius) during the day some deserts are always cold.


Did you know that desert animals have ways to keep themself cool. For example camels can go for days without food and water. Many deserts are nocturnal, that mean the some animal only come out at night. Some animal, like the desert tortoise in the southwestern United States spend much of their time underground.

The Mock Trial

Today we got a chance to experience a Mock trial. The trial was between Lee Jones and the Badger Aeromechanical Corporation. Lee Jones accused the Badger corporation of being the cause of his liver cancer which he was recently diagnosed with.His daughter was also diagnosed with autism.These two conditions can be caused by the chemicals they were exposed to from the Badger corporation.Both plaintiff and defense had very good and believable testimonies.With this being said the insurance company stepped in gave the plaintiff a settlement.

In conclusion it was a very interesting and educational experience for us.We learned what takes place and the procedures that occur in a court setting.We think the group as a whole and former Mayor John Street did a wonderful job.This experience is greatly appreciated.

Auditing the Tuttleman Computer Lab/ Breakout rooms.

The Tuttleman computer lab/breakout rooms have been the home base for our group for the entire program. We decided to audit this building for a few reasons, those reasons being, there are alot of computers and printers, and the building is freezing cold.

The computers are sectioned into groups of four, and each section has its own power strip. They all have their own power strip so students can plug in phone chargers and other things of that nature. The plugs are always on reguardless of weather students are using them are not. Also, there is a row of macs on the side of the lab that all have their own individual power strips that are always on reguardless of use. We think that if these were turned on and off on the basis of use it could potentially save alot of energy.

Also, the building is freezing cold at all times. The buildings temperature should be adjusted on the amount of people that are in it. It is ridiculas how cold the buidling is. We have to wear sweat shirts in the middle of July through August.

We feel with these few adjustments just this building alone could save Temple University alot of money and energy.
