Building Bulletin 101

Within Compliance Note CN4.1, reference is made to the appropriate industry standard for schools being Building Bulletin 101: Ventilation of school buildings (2014). This has been updated to BB101 2018, so either the current version or the specified 2014 standard may be used to demonstrate compliance.

If the thermal modelling specialist recommends an alternative standard, for example TM52, then this would be acceptable provided there is a full justification.
