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 5 743) 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.
