airtightness

This guide, released by the Building Services Research and Information Association (BSRIA), describes the conditional and unconditional methods of airflow measurement as well as the minimum benchmark method.  The document responds to a requirement in the England and Wales Building Regulations for mechanical ventilation air flow testing, by making sure that the methods used for measuring airflow rates are fit for purpose.  The aim of this guide is to help improve the standard of domestic ventilation installations.

Building airtightness (also called envelope airtightness) can be defined as the resistance to inward or outward air leakage through unintentional leakage points or areas in the building envelope. This air leakage is driven by differential pressures across the building envelope due to the combined effects of stack, external wind and mechanical ventilation systems [1].     [1] G. Guyot, F. R. Carrié and P. Schild, “Project ASIEPI – Stimulation of good building and ductwork airtightness through EPBD” 2010, 2010.
