Nowadays we can see that dependance in architecture almost everywhere. Lots of facilities, amenities and building in common which were built years ago have to be reconstructed, redesigned or they simply change their function because they no longer fulfil the needs and requirements of society. This is one of the main issues of sustainable architecture - to find a way to create variable spaces for different needs and maintain the efficiency through ages.

Sustainability in this large scale is a realy difficult and complex problem without proper solution yet. We can take a look on the design of the Olympic park for Olympic games 2012 in London, which was considered as the most ecological in the history. Despite of that most of the buildings were designed as sustainable, with minimum use of materials, lowering the impact on the environment, also with possibility of recycling of materials of temporary structures or parts of buildings designed only for the mass of people, so after the games it could adapt to the lower number of visitors etc. the main problem is that it's not working as sustainable complex, which could be integrated to the city as a part of it's metabolism. Therefore after certain period of time we can proclaim that it wasn't sustainable but least unsustainable.

For example the design of Plassen Cultural Center by 3XN Architects is designed for gathering of 100 to 100 000 people. The key for such a variability was to add to all surfaces and spaces more than one function - which depends for example from the part of the day. This provides great efficiency of the whole building.
LIGHT ARCHITECTURE
Designs of SANAA Architects is are msotly created by very light and subtile constructions and materials, which secure contact with exterior and the environment and are harmless toward the nature. Using those type of materials, in combination with recycling is also one of the important signs of sustainable architecture. Sustainable designs should take into consideration surrounding nature, and should create healthy place for living also for next generations.
