It amazes me, considering how frugal the Dutch are and how expensive energy is here, how little they do to save energy. On a hot day like today, the air conditioning is kept running at work. But there are radiators still heating up the place. In Iceland an building like that would have computer controlled air conditioning system that would either heat up the place or cool it down, depending on circumstances. Even using heat exchange systems as needed to heat the incoming air using the warmth from the outgoing air. In Iceland they would never do both, heat up using radiators and cool down using air conditioning, yet energy is so cheap there it's almost free.
