Notes that ventilation efficiency is not referred to directly in the new DIF standards for ventilation effciency. Reasons for this are that there are no clear definitions for the term or instructions on how optimum ventilation efficiency can be achieved under different operating conditions. Describes some measurements carried out on ventilation efficiency in non-industrial premises.
