The rehabilitation of buildings has been growing in the last few years, being one of the areas with greater investment by the public and private sectors. The challenge on the rehabilitation of buildings allows reducing the use of resources, trying to reduce the environmental impact and making the construction sector more efficient. The energy rehabilitation of buildings is an important aspect of building rehabilitation, assuming particular importance among this type of interventions, trying to integrate economical and rational measures. The adoption of BIM methodology is associated with project planning, cost or energy analysis of the construction and project deliveries of the building and constructed structures; as a result, nowadays there is a greater demand to adapt these tools in the early stages of existing building lifecycle. The emergence of BIM software that can combine the modeling with the energy assessments allows the designer to make more conscious, accurate and informed decisions about the projects under development. The main objective of the research study developed is to understand how the use of digital tools allows a more efficient approach in the energetic rehabilitation of a building. In this way, and considering different rehabilitation solutions, it is possible to perform an analysis of alternatives, comparing them with the base solution and thus being able to understand which are the energetic gains, as well as the optimal solution. The results will be presented making possible their comparison with real measurements and the standards reference parameters for thermal performance. The possibility of editing the thermal properties of the building materials considered allows the realization of various simulations with several combinations of possible improvements. The results obtained can be an integrant part of a cost–benefit analysis to support decision-making.
