“…Recent studies also confirmed that the uncertainty of fan pressurization measurements could not be neglected [21]. Furthermore, Carrié et al [22] recently highlighted, in particular, the influence of wind fluctuations and frequency on the uncertainty of building airtightness pressurization tests.…”

“…Also it has been adopted as a standard testing method by ASTM, CAN/CGSB, and ISO for demonstrating compliance and used in many voluntary standards across the globe, such as Passivhaus standard. Meanwhile, numerous scientific studies have been undertaken over the last few decades to investigate a wide range of building research associated with airtightness, covering unregulated or temperate/hot climate countries [ [56] , [57] , [58] ], its relationship with the infiltration, ventilation and indoor air quality [ [59] , [60] , [61] , [62] ], building characterization [ 56 , 58 , 63 , 70 ], retrofitting [ [63] , [64] , [65] ], measurement uncertainty [ [66] , [67] , [68] , [69] ], indoor air quality [ 70 ] and other relevant aspects [ [71] , [72] , [73] ].…”

As an important indicator of construction quality and envelope integrity of buildings, airtightness is responsible for a considerable amount of energy losses associated with infiltration. It is crucial to understand building airtightness during construction and retrofitting to achieve a suitable envelope airtightness which is essential for obtaining a desirable building energy efficiency, durability and indoor environment. As a convenient means of measurement, the current steady pressurisation method has long been accepted as a standard testing method for measuring building airtightness. It offers an intuitive and robust approach for measuring building airtightness and performing building diagnostics. However, it also has some shortcomings that are mainly related to its high pressure measurement, requirement for skilful operation, long test duration and change to the building envelope. Efforts have been made by manufacturers and researchers to further improve its accuracy and practicality with much progress achieved. Work has also been done to develop alternative methods that can overcome some of the issues. This paper provides a practical review on the incumbent methodology and efforts that have been made over the past decades in research and development of other methods to achieve a similar purpose. It compares them in relation to aspects that are considered important in achieving an accurate, quick and practical measurement of building airtightness and the finding shows other methods such as acoustic and unsteady technique have their own advantages over the steady pressurisation method but also add some of their own restrictions, which therefore makes them suited for different applications.
