We sent a questionnaire to chairmen of 3000 co-operative hosing association across Sweden to analyse their perception about energy efficiency aspects during June-October 2010; and 24% responded. About 80-95% of the respondents had no intention to retrofit their building envelope components during the next ten years measures. A greater proportion of respondents perceived that energy efficient windows were more advantageous than improved attic; basement and external wall insulation. Respondents gave high priority to economic factors in deciding on an energy efficiency investment measure. For 54% of the respondents; lack of expertise of the executive board to assess the benefits of energy efficiency measures was a barrier to energy efficiency investments. Majority of respondents considered economic policy instruments; like investment subsidies and tax deductions; as the most effective method to improve energy efficiency.
