Survey data on ventilation provision and use in homes in Great Britain.

This article describes data collected from an online questionnaire survey of 2, 039 adults in England, Wales, and Scotland (Great Britain) to assess the provision and use of mechanical ventilation, trickle vents, and windows in their homes. The survey was deployed on the 17th of June 2022 and collected data across four categories: socioeconomic and demographic characteristics, dwelling features, ventilation practices, and other contextual factors. The questionnaire included 65 questions and had a median completion time of 12 minutes, with all respondents completing the survey. The dataset is broadly representative of the British population and housing typologies. It provides valuable insights into the relationships between dwellings, occupants, their ventilation provision, and behaviours. The data is stored in a comma-separated values (.csv) file containing 396 variables, with responses formatted as binary, continuous, discrete, categorical, and free-text. This dataset can be utilised by academics for indoor environmental quality and energy modelling to refine assumptions about ventilation provision and practices. Public health professionals can use the data to estimate the health impacts of exposure to indoor pollutants, which can result from poor ventilation provision and to develop targeted health information. Government can use this evidence to inform policies and strategies aimed at improving ventilation in existing homes. The dataset is accessible through the Mendeley Data repository.
