Journal Article
Vega Pasos, A., Zheng, X., Smith, L., & Wood, C. (2020). Estimation of the infiltration rate of UK homes with the divide-by-20 rule and its comparison with site measurements. Building and Environment, 185, Article 107275. https://doi.org/10.1016/j.buildenv.2020.107275

Buildings are responsible for 40% of the global energy usage to which infiltration-caused heat losses are responsible for 30%. Air infiltration is the unintended flow of air through leakage paths and fundamentally determined by the airtightness of a...

On the power law and quadratic forms for representing the leakage-pressure relationship- Case studies of sheltered chambers (2020)
Journal Article
Zheng, X., & Wood, C. (2020). On the power law and quadratic forms for representing the leakage-pressure relationship- Case studies of sheltered chambers. Energy and Buildings, 226, Article 110380. https://doi.org/10.1016/j.enbuild.2020.110380

The leakage characteristics of a building can be described by a leakage-pressure relationship, which sometimes is referred to as flow-pressure relationship. This relationship provides the leakage rate through the building envelope when it is subject...

A practical review of alternatives to the steady pressurisation method for determining building airtightness (2020)
Journal Article
Zheng, X., Cooper, E., Gillott, M., Vega Pasos, A., & Wood, C. (2020). A practical review of alternatives to the steady pressurisation method for determining building airtightness. Renewable and Sustainable Energy Reviews, 132, Article 110049

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.

Experimental investigation of the impact of environmental conditions on the measurement of building infiltration, and its correlation with airtightness (2018)
Presentation / Conference Contribution
Vega Pasos, A., Zheng, X., Sougkakis, V., Gillott, M., Meulemans, J., Samin, O., Alzetto, F., Smith, L., Jackson, S., & Wood, C. J. (2018, September). Experimental investigation of the impact of environmental conditions on the measurement of building infiltration, and its correlation with airtightness. Presented at 39th AIVC - 7th TightVent & 5th venticool Conference, Juan-Les-Pins, France

The air infiltration of a building, which fundamentally depends on its airtightness, can be a significant contributor to its heat loss. It can also be affected by other factors such as external terrain, leakage distribution, sheltering factor and env...
