Blimey. I am ever so slightly flabbergasted by the response to my last blog post on mechanical ventilation with heat recovery. I thought it was rather obscure and just a little boring, but thus far I’ve had ten responses and just about everybody disagrees with me. And what’s more, they all seem so anguished. Can it be that this is actually a very critical topic, and that what we are confronting here is a crucial issue? And why do commentators feel so threatened when I question the Passivhaus orthodoxy?
All I am saying is that I am not yet satisfied that the airtight/MVHR build route is the “way to go” for all new homes. I’m not set against it; I’d just like it to be tested in lots of real life UK situations before we embark on it as mandatory. I don’t think it’s that time critical. A delay of three or four years is nothing compared to making a horrible mistake. If this was a drug trial, we would be spending five years and billions of pounds putting it through its paces: why should we accept any less from a critical element of our future wellbeing and future build costs?
As the last respondent put it:
We cannot afford further delays.
I think we can. I don’t think the ice caps will melt any faster if we stand back and assess for a little while, rather than charging in.
