Another 62 pages of guidance; what are the actual regulations?
As above, the regulations just call for "adequate" ventilation. So (where building regs apply) simply choosing not to provide any means of ventilation isn't an option. The next question is what is "adequate" - here the guidance documents (AD F and the DFCG) are useful as they set the bar of what is likely to be considered adequate. While you're free to choose some other approach if you prefer, if it doesn't perform as well (or is less convenient to use properly) as the approaches suggested, then you're unlikely to have met the 'adequate' requirement.
