Local strategies to promote energy retrofitting of single-family houses

Energy retrofitting of existing buildings is a central challenge for local, national, and international climate policies, and in several countries, single-family houses represent a major energy-saving potential. Although many municipalities are implementing local climate policies with initiatives to promote energy retrofitting of buildings, little research has been done regarding the role of single-family houses in local climate policies. Thus, we have little knowledge about specific initiatives to promote energy retrofitting amongst owners of single-family houses, we know little about experience from such initiatives, and we lack knowledge about the extent to which national and EU policies support local initiatives directed at homeowners. This article provides insights into these issues from an explorative study on local climate strategies in Danish front-runner municipalities where single-family housing is the dominating building segment. Based on a study of local governance strategies in 12 municipalities targeting homeowners’ engagement in energy retrofitting, the paper finds that these municipalities have developed promising local network-based ways to engage homeowners in energy retrofitting, but finds simultaneously that the national policy mix is only partly supporting these local initiatives. The paper also points out that the local and regional context for the programmes, including the local economic situation, is of great importance, and this context creates both potentials and challenges for the local programmes.
