Research into the effect of improving airtightness in a typical UK dwelling

The UK’s Airtightness testing & Measurement Association (ATTMA) is a trade body that represents the UK’s leading air-tightness testing and consultancy firms. Most of the work undertaken by these firms is for the builders of new housing and buildings, who are required to prove that they have achieved the required level of air-tightness in their buildings in order to satisfy Building Regulations.
