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 const... Read More about A practical review of alternatives to the steady pressurisation method for determining building airtightness.

An extended pressure range comparison of the blower door and novel pulse method for measuring the airtightness of two outdoor chambers with different levels of airtightness (2018)
Presentation / Conference Contribution
Wood, C., Zheng, X., Vega Pasos, A., Hsu, Y.-S., & Smith, L. (2018, September). An extended pressure range comparison of the blower door and novel pulse method for measuring the airtightness of two outdoor chambers with different levels of airtightness. Presented at 39th AIVC - 7th TightVent & 5th venticool Conference

The steady pressurisation method measures the building leakage in a range of high pressures, typically 10-60 Pa. It is implemented by creating a steady pressure difference across the building envelope and measuring the corresponding airflow exchange...

Experimental study on the measurement of building infiltration and air leakage rate (at 4 and 50 Pa) by means of tracer gas methods, blower door and the novel pulse technique in a detached UK home. Presented at 39th AIVC - 7th TightVent & 5th venticool Conference, Antibes Juan-Les-Pins, France

Air infiltration contributes to a heat loss typically representing up to one third of the heating demand of a building. The building airtightness, also quantified as air leakage, is the fundamental building property that impacts infiltration. The ste...
