A questionnaire survey of 1010 homeowners (response rate of 59%) in two counties in central Sweden viz.; Jämtland and Västernorrland was conducted to understand the influence of external actors on homeowners’ decision to install energy efficient windows. We complemented this survey with interview of 12 window sellers/installers in the Jämtland county. Majority of homeowners (74%) contacted more than one external actor for information when they plan to replace their windows. Window sellers/installers have a strong influence on homeowners’ window selection as 97% of homeowners bought the windows that were recommended to them. The sellers/installers recommended windows with a U-value in the range of 1.1 to 1.8 W/m2K and cited that condensation and high cost are the major drawbacks of windows with a U-value < 1.2 W/m2K.
