There is always something pleasing about it and often it's even witty. 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.
