Numerical and experimental validations of the theoretical basis for a nozzle based pulse technique for determining building airtightness (2020)
Journal Article
Cooper, E., Zheng, X., & Wood, C. J. (2021). Numerical and experimental validations of the theoretical basis for a nozzle based pulse technique for determining building airtightness. Building and Environment, 188, Article 107459. https://doi.org/10.1016/j.buildenv.2020.107459

Motivated by intentions of avoiding large net fluid flow and enabling a more practical airtightness test for large buildings, a low-pressure Pulse pressurisation technique was developed for measuring building airtightness at pressures that are consid...

Quantifying airtightness in Brazilian residential buildings with focus on its contribution to thermal comfort (2020)
Journal Article
Rodrigues, L., Tubelo, R., Vega Pasos, A., Gonçalves, J. C. S., Wood, C., & Gillott, M. (2020). Quantifying airtightness in Brazilian residential buildings with focus on its contribution to thermal comfort. Building Research and Information, https://doi.org/10.1080/09613218.2020.1825064

© 2020 Informa UK Limited, trading as Taylor & Francis Group. Airtightness refers to the amount of air leakage through a building’s envelope. This uncontrolled exchange of air between inside and outside, either infiltration or exfiltration, may lea...

Estimation of the infiltration rate of UK homes with the divide-by-20 rule and its comparison with site measurements (2020)
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.
