Plenty of scorn has been poured on the way that the zero carbon homes target has been watered down, then watered down again, as if it were a homoeopathic remedy for climate change.
Others, notably Nick Grant and Doug King, have led the charge against the very concept of zero carbon buildings as being an illogical concept that diverts construction from what it could be doing best — and I cheerfully count myself among their followers.
However, on the particular point of the current government consultation on the Allowable Solutions element of “Zero Carbon Homes”, I do think it is worth engaging – as there is an opportunity to make the arguments that high fabric standards should be at the heart of the zero carbon policy. Who can say how long the Zero Carbon Homes policy will last? – however, the better the fabric standards we have at the core of it, the better placed we’ll be to replace it with something more sensible.
I have had a look at parts of what DCLG is consulting on, and describe and comment on what I found, in the article below.

STOP PRESS! Doug King has shared his response to this consultation, making the case very thoroughly that “offsetting” energy use and carbon emissions from housing, by reducing energy use and emissions in other sectors, is a nonsense. Those other sectors should be making those cuts anyway – all selling them off as “allowable solutions” does is to pick off the low-hanging fruit from another sector, making it more expensive for them to do what they need to do. The net effect would probably be to reduce energy use an emisissons LESS than you would if proper energy and carbon standards were applied to housebuilding in the first place.
