ROOFTOP LANDSCAPING | 06 Aug '08 from the editors
Summer in the city means a rise in pollution from the 'urban heat island'. Cities remain warmer than suburbs from the lack of evaporation and vegetation but implementing landscaping on roof tops is providing relief. By building green roofs, landscaping the roof tops with sedum and other vegetation, negative environmental impacts from the urban heat island are greatly reduced-- see more here
Energy savings on the operation of power generating plants show a reduction of carbon dioxide. More days at the beach also result from the reduction in storm water runoff. Less pollution, less erosion and reduction of green house gasses, all from combined efforts of landscaped rooftops. Green roofs also provide opportunities for local food production. These landscaped roof tops are beautiful and practical, lasting up to twice as long as regular roofs. Urban ecology has far ranging consequences and green roofs are providing a new eco-friendly direction.
What is a green roof, or "living roof"? | 03 Apr '07 from Eric Corey Freed
A green roof system is an extension of the existing roof, and not potted plants as many assume. The system consists of a special water proof and root repellant membrane, a drainage system, filter cloth, a lightweight growing medium and plants on top.
Green roof systems may also be modular, with the drainage layers, filter cloth, growing media and plants already prepared in movable, interlocking grids or trays. These are good for areas where access could be an issue.
In North America, the benefits of green roof technologies are poorly understood, despite the efforts of several industry leaders. In Europe however, these technologies have become very well established. Cities like Chicago have launched a Green Roof Initiative, serving as a model for other cities.

The Open Architecture Network | 02 Apr '07 from the editors
The Open Architecture Network is a collective space for sharing innovative building ideas from around the world, or, in their own words, "dedicated to improving living conditions through innovative and sustainable design."
You can search by project location or type, add your own project, and even manage a project team using the site's tools. Projects range from the fanciful in(out)side house at left, to the Biloxi Model Home being built by MC2 Architects for a shrimp-boat operator who returned after the Hurricane Katrina evacuation and "found that his house had floated 50 feet away and into to the middle of Crawford Street."
A living roof can lighten your mood | 29 Mar '07 from the editors
Living roofs have the potential to do a number of wonderful things for the environment—they create habitats for local birds, they control harmful stormwater runoff and, by alleviating the urban heat-island effect (and the intense need for air conditioning), they reduce greenhouse gas emissions.
But, for a moment, putting global warming and carbon dioxide levels aside, we ask: What will putting a garden on your roof do for your mental/emotional state? Well, that might just depend on where you live. If you live in rural New Hampshire, chances are, it won't do much more than make you feel good about youself and your generous contribution to the environment. On the other hand, if you live in Detroit, it might just save you a few visits to your favorite psychologist's couch. According to Linda S. Vasquez, one of the foremost experts on green roofs, rooftop gardens have ecological, economic, aesthetic and psychological advantages.
