Knowledge of the label20 % of the Danish respondents declare that they do not have a label on their house:
• Even though we have drawn their address from a register of issued labels
• …and even we during the survey show them a picture to help them remember the label
• Explanation: they have never received it, they forgotten it, they did not notice it …?

Recommendations 1. Increase users trust in the label and in its usability
2. Include direct dialog with the energy advisers
3. Focus on those houses that need it the most (the oldest houses or those with the worst label)
4. More economic instruments related to energy renovations
5. House owners interest in energy renovations as compared to other renovations
