The Modern Movement played an unquestionable role in the renewal of architectural ideals, bringing a new attitude towards understanding the ways of living, technique and aesthetics, marking profound changes in the general perception of the world. The Argentina´s modern movement dates from 1930 to 1970. It includes, in many cases, original approaches associated with new modes of thought, manifesting an architecture resulting from the analysis of the local and regional conditions from its cities.In the province of Tucumán, Argentina, the architect and theorist Eduardo Sacriste (1905-1999) was a pioneer in modern bioenvironmental design. His project is based on his knowledge of the climates of the province, the application of bioclimatic guidelines and the definition of spaces according to the behavior guidelines of its recipients. Among his works, two hospitals stand out that today are constituted as architectural heritage: The Hospital of the Child Jesus (1948) and the Institute of Maternity and Gynecology Our Lady of Mercedes (1958).Both buildings respond to the typical architecture from the modern movement in their morphology and they present bioclimatic criteria in their design. On a previous study it was determined that, from the reforms carried out for functional reasons, these buildings lost part of their original character as well as issues of natural thermal conditioning, while still retaining some of the characteristics of the modern movement and bioclimatic properties with the that were originally projected.Current, through global climate change, most of the strategies applied for natural thermal conditioning are still efficient. However, the thermal insulation provided by the envelope is insufficient for the region´s climate. This work proposes an energy rehabilitation of the building envelope to improve its thermal performance, without damaging the original aesthetics.
