MAUT for the energy upgrade of dwellings

The aim for generating this data is to explore the contribution of ecolabel HVAC systems, which are already available in the market, to the energy upgrade of existing dwellings, placing emphasis on whether they can constitute an efficient means of dealing with energy poverty. A parametric energy upgrade analysis is carried out, with environmental, social and economic criteria in the four climatic zones of Greece and three building types. Additionally, the specific criteria are prioritised, using the Multi-Attribute Utility Theory. Based on this analysis, conclusions are drawn, concerning the most advantageous energy saving actions, from an energy, environmental, social and economic point of view. It is found that certain synergies of ecolabel HVAC systems with RES systems can be effective and practical energy saving solutions for the residential building stock. These energy saving retrofitting actions could be put forward as realistic solutions to face energy poverty at a techno-economic level.
