SUMMARY:

Buildings of modern architecture that do not receive recognition for their historical and cultural values are often neglected, which can lead to the loss of their original characteristics and functional obsolescence, or even demolition. This occurs due to lack of appreciation, abandonment, regulation, or preservation instances. A viable solution to this impasse is energy retrofitting, which has the ability to renew them, maintaining their original aesthetics, increasing their lifespan and performance, and meeting the needs of users. In this context, the dissertation aims to enhance the approach proposed in a recent study that evaluated non-residential buildings of modern architecture, in order to conceive a simplified decisionmaking matrix that combines heritage preservation and energy retrofitting criteria for the treatment of building envelopes that do not have an instance that supports and declares their heritage value. To achieve this goal, Brasília was taken as a case study, since it predominantly embodies the characteristics of Brazilian modern architecture and potentially has more features to be preserved in a renovation process with a view to better natural lighting and energy efficiency. It was possible to systematize, test, evaluate, and optimize a set of methods developed by the aforementioned research. Among the improvements made, the inclusion of values to be preserved in the building stands out, starting from the identification and hierarchization of them. In addition, parameters were established to command the intervention project, which include the declaration of cultural significance and the expression of the order in the composition of the facades that dialogue with the expression of the structural forms, visible or not, as well as in the volumetric composition, such as the order and proportion. Thus, a common coefficient was created to unite these different strands of analysis, called "Visible Facade Value (VVF)", expanding the typologies of facades and adapting a heritage valuation scale that is in accordance with the general guidelines of the project, making it more comprehensive and complete. To verify the applicability of these changes in the evaluated methods, a representative sample was selected, consisting of 12 non-residential modern architecture buildings, and grouped according to criteria such as number of floors (0 to 4, 5 to 10, or 11 to 16), year of construction between 1960 and 1980, and varied forms of facade finishing, such as fine grid, open grid, boxed, and curtain wall. After the geometric characterization and energy efficiency variables of the sample, the decision-making process consisted of evaluating the attributes of significance and structure to determine the preservation hierarchy. The process concluded with the indication of general intervention guidelines and more precise solutions for each building, considering both heritage preservation strategies and energy retrofit.
