We have environmentally housing near us called Bedzed which has been up for about 20 years. In all that time it has been upheld as a great example of new housing and I couldn't work out why people keep talking about it but not building more of these houses.
BedZED homes are kept at comfortable temperatures with fresh air
using simple passive architectural techniques rather than high tech
solutions according to their website.
However - I've been to meetings there in the summer and it was very hot and humid which appears to suggest that there may be a problem wiht the technology. Much as it pains me to say this, perhaps the "passive architectural techniques" they use do not conform to the standards that Dr Feist expects.
