GREEN ROOF AND LIVING WALL IN THE ROLE OF ECOSYSTEM IN SUSTAINABLE URBAN DWELLING

It has been said that something as small as the flutter of a butterfly´s wing can ultimately cause a typhoon halfway around the world. Chaos Theory effect can be applied in an actual climate change issue. Forests, fields, gardens, and natural areas are being replaced with concrete, bituminous and unnatural surfaces. Necessity of recovering green spaces and natural areas is becoming more critical. Questions of sustainability, improving quality of life, solving current ecological issues are goals urban and architecture community can solve. Key factor of not forgetting about nature we have been given is designing healthy green cities, covering building in plants, integrating wildness in cities, designing and constructing vegetative roofs, living walls, implementing green policies. Integrating nature to city may seem fashionable, expensive and not necessary. Microclimate and building´s ecological footprint is very high. Balance of artificial and natural environment is way how to maintain sustainability. Co-operation of landscape and dwelling is bringing nature to city. Green is one of the key elements in environmental strategy. Balance means minimizing of breaking close ecosystems. Designing one big artificial ecosystem that wouldn´t be destroying real natural ecosystem is the goal of this paper. Urban ecology and environmental issues need to become an integral of development, construction, policy and way people think. Green roofs and living walls offer solutions how to find a place for nature in designed world. Positive approach on local scale may cause positive worldwide impact. Like the flutter of a butterfly´s wing.
