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
