Impact of Replacement Windows on IAQ of Occupied Dwellings

The project involved the following work:

• Identification and a telephone survey of 250 houses in which windows have been replaced
• A detailed physical survey of houses in which the IAQ had deteriorated following window replacement
• Fan pressurisation testing of 10 houses before and after windows replacement
• Air permeability testing of replaced windows
• Determination of the change in the air infiltration rate caused by window replacement both for individual properties and the UK stock in general
• Analyses of the risk of causing IAQ problems as a result of installing replacement windows using ‘Condensation Targeter’
• An investigation of the effect of installing trickle ventilators in replacement windows.
