Buildings are an important source of CO2 emissions and account for almost a third of final energy consumption globally. The necessity to achieve energy efficiency standards in new and existing buildings is now recognised. The residential sector consumes 25% of the global energy and is responsible of 17% of the global CO2 emissions. EU governments have developed different support measures to decrease energy consumption in the residential sector. However, energy renovation by individual homeowners is lagging because the support measures do not take into account concerns of homeowners. This study is part of Sustainable housing for strong communities (Stronghouse) project, which aim to propose new tools and redesign support measures based on a better understanding of the drivers that motivate homeowners. This paper proposes a new userfriendly web-based multi-criteria decision-making tool that aims to empower homeowners to select the appropriate energy improvement method for their home fitting their criteria. The set of criteria that will be included in the application will be based on the preferences of residents obtained through questionnaires. A layered approach will be used to develop the proposed web application.
