Nor does it have to be expensive. Smart architecture is architecture with a smile - and a sincere one. This does not only apply to the physical environment - the climate, the urban landscape etc. It is also true for the social environment, for the political and historical context. Smart architecture cooperates instead of fighting.
Smart architecture is efficient.
It's the optimal relationship between means and ends. Smart architecture is techno-logical. Technology is an important tool but not a goal in itself. On the other hand fear or distrust of technological solutions is pretty stupid. The tremendous assault mankind has made on the earth over the ages is largely due to the production and use of the growing arsenal of artefacts with which we like to surround ourselves.
