During the summer, we grow fresh herbs on the roof of the restaurant. Among other items, we grow basil, mint, edible flowers, and tomatoes which, picked the same day, will probably be found in the dish or cocktail you order!
I passed a site of small wind and solar installations on the campus of a branch of our community college. The wind turbines are vertical axis (VAWT).
This LEED Platinum home exhibits a large variety of sustainable features, including this notable cork flooring. Cork has excellent properties for such an application, in addition to giving a soft, warm color to the house interior (though other cork flooring can come in many patterns and colors as well).
Due to its highly porous composition, cork is able to better absorb impacts and provides very good acoustic and thermal properties, which are greatly beneficial to a home. It is also a highly renewable material, and exhibits a long list of other excellent aspects, as detailed in the last half of this page (click thumbnail below):
On one of our roofs, we maintain this rooftop garden. Not only does it allow for a more efficient use of space, but it also serves to help cool the roof in the summer, as rooftop gardens can provide better insulation than standard tar or gravel use, and help to remove heat from the air.
