Anyone heard of this . They are doing this on alot of skyscrapers in Atlanta. Keeps city heat down.
Eco friendly.
I really like this idea.

A few up here but not many. Talk is the new hotel on the lake will have this. Not really too popular.
this one looks pretty cool to me
I like that one. Water shed run off is a big problem here and that would help.
Our fearless leader has already made it some kind of ordinance here. I think all new box stores, high rises, and even sky scrapers have to abide. It's nice in the ghetto, cuz you can shoot your dealer and then go to work at the city's only WalMart, complete with a nice roof top lawn. You can shoot people here but you better F'n have a green roof or the strong hand of the Daley family will smack yur arse.
Go Green! :mj07:
Thank you Mayor Daley
Go Green! :mj07:

NEW - Chicago, Il. No. 1 On Top 10 List Of Green Roof Cities For 4th Time
With more than half-a -million new square-feet of green roofs installed in 2007, Chicago leads in becoming the greenest City in America. ?Cities are no longer the enemies of the natural environment,? says Chicago Mayor Richard M. Daley of the news.:00hour
at least your number 1 at something, it could be like baseball:SIB

What is a green roof made of?
Starting from the top, an extensive green roof has a layer of plants, which are typically sedums. These are low-growing, shallow rooting, drought tolerant plants. There are many different varieties of sedum, with different different coloration and different flowerings, so that a roof can have a varied appearance, rather than looking like an entire crop of a single variety. The plants are in a growth medium, an engineered mixture of lightweight soils, vermiculite, and other materials that provides a good environment for the sedum.

as smurph would say, you dont need Jesus to maintain this roof

Vinnie installed one over his blue roof and immediately put his goats up there.

think about it. No water runoff, and birds can live on your roof.
What Are Green Roofs?
A green roof consists of vegetation and soil, or a growing medium, planted over a waterproofing membrane. Additional layers, such as a root barrier and drainage and irrigation systems may also be included.
Green roofs can be used in many applications, including industrial facilities, residences, offices, and other commercial property. In Europe, they are widely used for their stormwater management and energy savings potential, as well as their aesthetic benefits.
What Are the Benefits of Green Roofs?
Green roofs are an attractive roofing option that can reduce urban heat islands by providing shade and through evapotranspiration, the release of water from plants to the surrounding air. They also:

Reduce sewage system loads by assimilating large amounts of rainwater.
Absorb air pollution, collect airborne particulates, and store carbon.
Protect underlying roof material by eliminating exposure to the sun's ultraviolet (UV) radiation and extreme daily temperature fluctuations.
Serve as living environments that provide habitats for birds and other small animals.
Offer an attractive alternative to traditional roofs, addressing growing concerns about urban quality of life.
Reduce noise transfer from the outdoors.
Insulate a building from extreme temperatures, mainly by keeping the building interior cool in the summer.
How Do Green Roofs Mitigate Storm Water Runoff?
As impermeable surfaces like buildings and pavement replace open space and vegetation, green roofs can play an increasingly important role in storm water management. During rainstorms, green roofs act as a sponge, absorbing much of the water that would otherwise run off. Researchers estimate that three to five inches of soil or growing medium absorbs 75% of rain events that are one-half inch or less.
Green roofs also filter pollution from rainwater. This is achieved by the root systems' bacteria and fungi, which utilize the natural filtering processes of bioremediation and phytoremediation . As a result, the non-point source pollutants, nitrogen and phosphorus, are broken down and detoxified. This beneficial process increases over time as rooftop plants and root systems mature.
Are Green Roofs Cost-Competitive with Traditional Roofing Options?
Currently, the up-front cost of an extensive green roof in the U.S. starts at about $8 per square foot, which includes materials, preparation work, and installation. In comparison, the cost of a traditional built-up roof starts at about $1.25 while cool roof membranes start at approximately $1.50 per square foot.
Extensive green roofs cost more than traditional roofs because they require more material and labor for installation. Another factor affecting price is that green roof contractors are limited in number. As the demand for rooftop gardens increases in the U.S., and as additional contractors come into business, up-front costs will likely decrease.
However, it is widely known that up-front costs do not tell the whole story. Taking into account future summertime energy savings at the time of purchase brings the price of a green roof closer to that of a traditional roof. Depending on local construction codes, it also may be possible to do without storm water infrastructure investments.
Another factor reducing the cost of a green roof is that vegetation can extend the life of a roof. This is because less solar energy reaches the roof substrate, limiting damage from UV radiation as well as daily temperature fluctuations, which cause repeated contraction and expansion.

this green roof stuff has potential
We'll also be #1 this fall with the highest sales tax of any big city in the US.
I can only pray that we don't get Daley's Olympics.
They may have finished Millinium Park last year. Key word "Millenium" as in "complete by 2000". This guy is the biggest crook ever to stand in front of a tv crew. Puts his old man to shame.
