This is the warmest place in winter I have ever lived in with the coldest houses (Southland)
Even new houses are being built with bad solar design and poor insulation
The time to fix this is with new build - it is so much cheaper then than at any time later
People build houses with the minimum insulation - short sighted but what they do!
We need to increase the minimum standard!
The house I have just had built in Southland is a 160m2 three bedroom house that can be heated (the whole house) on the coldest Southland days with 1Kw electrical power - it's not rocket science!
