Debate on the costs of Code 6 and Zero CO2

See Buildings website for  a debate in progress, most interesting comment so far from Neil Jefferson of the Zero Carbon Hub: I think the principles of Passivhaus have provided a good steer for us, but for the UK climate and grid carbon intensity, it is very unlikely to provide a cheaper alternative to the emerging defintion for zero carbon new homes. Energy efficiency is the first and most vital component of carbon reduction, but Passivhaus as a minimum standard per se, is not the most cost effective solution.

Interesting comment from Kirk Archibald from Fairview Homes

[Comment From Kirk Archibald Kirk Archibald : ]

why does the definition of zero carbon include emissions from discretionary energy use? this is anlagous to asking car manufacturers to legislate for the way their customers drive; or where they manufature zero emission tailpipe cars, asking car manufacturers to contribute towards the decarbonisation of the grid. if the definition were restricted to regulted emissions, I suspect the industry would embrace this wholeheartedly.

And finally fromMark Elton of ECD

Please find it within yourselves to give Passivhaus parity with Allowable Solutions. It is the only sensible strategy.
