AB The reduction of energy consumption in the residential sector presents substantial potentialthrough the implementation of energy e ciency improvement measures. Current trends involve theuse of simulation tools which obtain the buildings’ energy performance to support the developmentof possible solutions to help reduce energy consumption. However, simulation tools demandconsiderable amounts of data regarding the buildings’ geometry, construction, and frequency ofuse. Additionally, the measured values tend to be di erent from the estimated values obtained withthe use of energy simulation programs, an issue known as the ‘performance gap’. The proposedmethodology provides a solution for both of the aforementioned problems, since the amount of dataneeded is considerably reduced and the results are calibrated using measured values. This newapproach allows to find an optimal retrofitting project by life cycle energy assessment, in terms ofcost and energy savings, for individual buildings as well as several blocks of buildings. Furthermore,the potential for implementation of the methodology is proven by obtaining a comprehensive energyrehabilitation plan for a residential building. The developed methodology provides highly accurateestimates of energy savings, directly linked to the buildings’ real energy needs, reducing the di erencebetween the consumption measured and the predictions.
