Interesting Green Roof designs.

Cali. Academy of Sciences Green Roof

This is a really neat one incorporating a natural look with the artificial with the sun roofs on the "hill" tops.

Here is another I don't know much about but it just looks neat.

Personally, i don't understand how they can push this as a green roof.
Being built green means be built environmentally friendly, through design, construction and sustainabiliy.
The only way this has any environmental impact the fact that is uses some of the rain water instead of it being run off in the sewer system.
That being said, this roof is no more green than the average roof in regards to the building envelope. Meaning things like heating and air/water infiltration/exfiltration.

It is neat though, lawn on your roof.

Green Roofs are called that because they are ummm green. Their benefits are actually much greater then you believe.

Here are the benefits.

* Provide amenity space for building users — in effect replacing a yard or patio
* Grow fruits, vegetables, and flowers
* Reduce heating (by adding mass and thermal resistance value) and cooling (by evaporative cooling) loads on a building — especially if it is glassed in so as to act as a terrarium and passive solar heat reservoir
* Reduce the urban heat island effect
* Increase roof life span
* Reduce stormwater run off — see water-wise gardening
* Filter pollutants and CO2 out of the air — see living wall
* Filter pollutants and heavy metals out of rainwater
* Increase wildlife habitat in built-up areas — see urban wilderness
