Is the future looking bright for the houses without heating?

Haus 2226 in Austria harnesses natural energy. We ask architect Professor Dietmar Eberle how Irish buildings could follow suit 

Haus 2226 in Lustenau, Austria.

Energy efficiency is often achieved by hi-tech retrofits, but Baumschlager Eberle Architekten has made 2226 a blueprint for the future — a building without air conditioning technology.
