Abstract

The following paper shows the results of the ZenN European research project, in which the SSH-methodology has been implemented in order to collect information on user awareness, preferences, needs, behaviours and for energy efficient renovation solutions. Taking this into account, the barriers which limit opportunities for improvement of energy efficiency at the decision-making phase of regenerations and challenges encountered in practical parts of EE-renovation activities are characterized. The SSH analysis shows that the social barriers and challenges identified in the project were implied by insufficient knowledge or interest in the idea of energy-efficient buildings and high investment costs. Furthermore, several country-specific factors have been found, such as insufficient education and promotion activities, historical and cultural values of buildings which limit renovation opportunities etc.
