This research aims to evaluate the conditioning that determines the thermal comfort in the Educational Institutions of the Puno Region. The schools of the study site lack thermal comfort due to the existing low temperatures, so the study evaluates the conditioning that allows determining the thermal comfort in the Educational Institutions of the Region. The methodology used in this context is experimental since measurements have been made in situ, obtaining results that allow comparing and demonstrating the use of passive materials in the classrooms to improve the interior conditioning, bringing; as a result, an efficiency of 85% as a conclusion we can say that the implementation of passive materials inside the classrooms, helps to improve thermal comfort.
