Abstract

Energy retrofitting of the existing dwelling stock represents one of the major challenges for the transition to a low carbon society, as about 19% of the final energy consumption in the European Union relates to heating of dwellings. Danish homeowners experiences with the Energy Performance Certificate (EPC) are examined, as it was introduced in 1997 (prior to a similar scheme introduced later in the European Union). The main research question is whether the EPC has an influence on Danish homeowners energy retrofit practices. Homeowners understanding of and trust in the EPC are analyzed, based on an online survey of homeowners (N = 743) living in a home with a recently issued EPC. Results indicate that the EPC has a limited influence on homeowners energy retrofit practices. Despite most homeowners finding the EPC reliable and easy to understand, relatively few find it useful as a source of information for home retrofits. In its current form, the EPC is insufficient to encourage homeowners to undertake energy retrofits of their home. Improvements to address this problem in the administration, scope and layout of the EPC are suggested.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
