Roof gardens and parks for sustainable cities
The cities of the future will be under a carpet of vegation. So compelling are the reasons for this policy, they can scarcely be evaded:
- roof vegation has the most beneficial consequences for surface water management
- roof gardens have excellent thermal properties: the insulation they provide makes buildings warmer in winter and cooler in summer
- extensive roof gardens provide wonderful habitats for wild life
- roofing membranes last longer when protected by a cool damp layer of vegetation
- in dense cities, outdoor space is at roof level is often pleasanter than outdoor space at ground level: it is quieter and less polluted. These are known as 'intensive' roof gardens
- plants on roofs take in carbon-dioxide and give out oxygen
- vegetated roofs collect dust which otherwise pollutes the air
Cycling and roof-gardening are two of the cheapest and best policies for making cities more sustainable.
