The sustainability goals agreed by most countries have made them focus their attention on the high energy consumption of buildings and the weight within this consumption of the residential sector. This makes the energy rehabilitation of existing buildings a top priority. However, energy rehabilitation is not the same in all countries. In this study, we analyse two houses in Zaragoza, one rehabilitated with an external thermal insulation system (ETICS), while the other retained its original state. Their energy behaviour was monitored and the results of each case were analysed. The results obtained from this monitoring were used to propose rehabilitation strategies in single-family social housing in Saltillo, Mexico, where the residential sector is the third-largest energy consumer. This study demonstrates the interest in analysing and using successful real cases of energy rehabilitation interventions in similar climates as a useful knowledge transfer opportunity. In addition, the importance of this "technological know-how" is highlighted to carry out a more precise energy rehabilitation.Peer ReviewedPostprint (published version
