Hi, I'm looking at the recommended allowances for air infiltration rates in the 'CIBSE Concise Handbook' (Table B1.5 page 47).
The values vary considerably from those given in CIBSE guide A, tables 4.13 - 4.21 'Air Infiltration Rates'.

Can anyone explain the differences?

Other than one being a very short form version giving typical data (not targets) I suspect it may well be changes in building airtightness since 2006 Part L, good engineering practice etc

I don't have either document to hand at the moment, I'll take a look later
