The Architecture, Engineering and Construction communities have been motivated to manage the building resources more efficiently. The call for sustainability, the question of scarce resources, the useful life of buildings, the need to reduce operating costs, stricter laws, and a certain tendency to reuse and recycle components, are responsible for such a position. As many of the impacts caused by the construction industry come from the energy consumption of the buildings and the phase of their operation represents the longest period and also the highest energy consumption in its life cycle, the Energy Life Cycle Assessment (ACVE) is essential to demonstrate and quantify such impacts. At the same time, retrofit processes have potential applications in existing buildings, since they reduce the impacts caused by the construction of new buildings, and can increase operational and energy efficiency through the incorporation of new technologies and concepts. The objective of this research is to evaluate the performance of the envelopment and energetic life cycle of public school buildings, through retrofit actions. For the demonstration of results, a standard CMEI of the Municipality of Vitória - ES was selected as the model. In order to analyze the performance of the envelope, the method used was the computational simulation, using the EnergyPlus software. For ACVE, the incorporated and operational energy and CO2 emissions were considered at each stage, comparing the current situation of the building and the proposed retrofit actions. Among the most effective measures are the ventilated façade and the replacement of the roof covering, both for envelopment performance and for the energetic life cycle of the building. It is hoped to help decision-makers by the agents involved in the process, as to the feasibility of adopting materials and construction systems aimed at reducing the energy consumption and environmental impact of public building.
