This report details the post-occupancy evaluation of five families in Germany, Austria, France and the UK living for a year in the Model Home 2020, an experiment launched by the VELUX Group to contribute actively to the development of sustainable buildings of the future. The survey was carried out seasonally during the year and the questionnaire covered energy consumption and production, indoor climate and air quality, daylight and electric lighting, house automation and sustainability. In general, the families reported that their expectations were fulfilled. They reported high satisfaction with the indoor environment, improved wellbeing and fewer sick days, improved sleep quality, that the house automation was easy to use and that being able to follow energy consumption and production is extremely helpful.
