ANTARCTIC MODULES THERMAL PERFORMANCE EVALUATION OF THE EMERGENCY ANTARCTIC MODULES The Emergency Antarctic Modules have been serving to the continuity of Brazilian researches since 2013, after the fire that destroyed the main part of the Comandante Ferraz Antarctic Station. The occupation in the place follows the precepts of the Antarctic Treaty and its Protocol on Environmental Protection. By this reason, the use of fossil fuel for heating must be minimized and, on the other side, it is necessary to guarantee the well-being of the users. The aim of this work was to evaluate the performance of the building, regarding to its capability to maintain the internal temperature stable. The procedures consisted in: 1) collecting data, choosing the places for internal measurement and installation of equipment; 2) identification of the “coldest” or winter period and the “hottest” or summer period, according to climate data and reference methodology; 3) verification of the correlation between the external and the internal measured temperatures, through scatterplots; 4) evaluation of the stability of the internal temperature, through control charts. The results showed no correlation between the internal and the external temperatures, which denotes a good insulation of the envelope and/or that the heating system is capable to compensate the differences of temperature. The refectory presented many points out of control, for the entire period of measurements and in the summer period. The cabin C3 also presented instability, especially in the winter period. The cabin B2 had uncontrolled temperatures at 0.10 m height, only, in the winter period. In contrast, in the infirmary, the temperature remained stable.
