Airtightness - Measurements and Measurement Methods

摘要

This paper describes different methods of measuring the airtightness of whole buildings, and reproduces the greater part of the results of measurements which have been made in different places, primarily using the pressure method but also using the tracer gas method to some extent. The pressure method is described together with the recommended method (SP 1977:1) published by the National Swedish Authority of Testing, Inspection and Meteorology, which is explained and commented upon where necessary. A number of variations of the tracer gas method, as used for measuring the ventilation in a building, whether continuously or occasionally, are described, together with descriptions of suitable equipment.
