The lecture on green roofs and gardens really got me thinking about the many opportunities and different methods of implementing these into the urban environment. Daniel Libeskind’s has designed a green new york tower that combines urbanism with trees and greenery. This 54 foot condo building is made out of many glass windows with green gardens throughout the tower. Openings are cut into the tower where these green “roofs” are placed. These openings also provide balconies for those situated near them.

This design caught my eye because it solves the problem that my studio group members and I struggled with in the creation of our artificial city. Since our “airport” city was very dense and consisted of only large towers (no smaller forms residential housing), we had searched for a way to provide individual green space to these towers inhabitants. Our solution was to implement rotating towers. We hadn’t exactly worked out the details, but had intended to eventually use this technology to provide greenery. Daniel Libeskind’s design is exactly the idea we were looking for. It literally takes the outdoor environment and brings it inside. The residents living in the upper portion of the tower may no longer feel as if they are as far from the ground as they really are. They can look out into a green garden they may only be a few stories down. It’s a brilliant idea and a step towards solving the many issues we need to address now and in the future.
Hanging gardens use layers of trees and vegetation. There is a Poem which describes these layers.
Scandinavian Turf Roof – berch bark.
Modern Experiements: in the 50’s. There can be a social point on the rooftop, like a daycare.
Green roofs and roof gardens: Small, high density housing with green roofs in Switzerland. Cannot see the high density nor does one feel it, because the view of the green/trees etc.
Amenity and Aesthetic benefits: recreational space, public and private, high quality and high density.
Environmental Benefits: biodiversity and wildlife, value stromwater management, air pollution, urban heat island effect.
Economic Benefits: increased roof life, cooling insulation and energy efficiency, green building assessment and public relations.
1 of 10 roofs in germany are green. The main reason being that Germans have a law to preserve nature. Must compensate for what they consume, many decide to use a green roof to do so.
Three types of roof construction: - inverted (roof deck, waterproof root-proof, drainage layer, filter mat, substrate/ growing medium) – cold (insulation, roof deck, waterproof root-proof) – warm ( roof deck, insulation, waterproof and roof proof)
Green Roof: extensive roof-greening (maintenance extensive, inaccessible, low weight, low cost, no watering), moss/sedum communities, dry meadow communities, 10 kg/m2 (weight of vegetation).
Green Roof Hybrid: simple intensive roof greening (maintenance extensive, accessible), dry meadow communities, low-growing drought-tolerant, perennials, grasses, 10-20 kg/m2 (weight of vegetation)
Roof Garden – intensive roof-greening, 10-150 kg/m2 (weight of vegetation)
Works:
-Castle Horst in former times
- Ackermannbogen Apartment Block
- Park Village Unterfohring – underground parking preventing trees from being planted directly on the plaza (just around the edges), grass growing between stones.
- Five Courtyards in Munich
- Portiahof
- Promnadehof
- Perusahof
- Light Well – rooftop surrounded by doctors (waiting rooms, etc.)
- Roof Terrace
