While the examples were from North Africa and the Middle East, the
point was more about using technology intelligently and not ignoring
something because it is hundreds of years old. Sometimes the solutions
are already being used in other cultures or were being used locally
until a while back. In many ways in trying to build a standard house
or using electronic devices to a job, we fail to realise that there
are already effective technologies available to keep a builing warm, a
building cool or keeping the water away fromt the floor. This is a
general comment, since there are certainly buildings that adhere to
smart design, but there are also so many that don't. Also as stated in
other comments there are new technologies that build on and improve on
what already exist.
For me passive-energy is something I like to think about in buildings
- that is letting natural physics do the work, rather than throwing a
motor in to do the work, if at all possible. With concerns about
energy expenditure I would like to see more energy concious designs
come into play. I haven't been everywhere and I haven't seen
everything so I am hoping to find out other technologies that have
maybe ignored that we could reintroduce. The point about some houses
not having over-hanging roofs to create shade, or keep water away from
the main structure, which was brought up in another comment, is an
example of where we build and miss something out because we didn't
understand their importance.

I was using it to describe a vertical structure through which heat
escapes.
