Análisis y mejoramiento del confort térmico en aulas de la Universidad La Gran Colombia

Abstract

The Gran Colombia Univeristy, central headquarters, is made up of different buildings that present variable thermal situations, because of their materiality or location. As a result of this variation, some classrooms have situations that make their occupants feel uncomfortable when they stay inside for a long time, due to a high or low temperature. This research was developed based on the Fanger methodology in order to be able to verify from a qualitative and quantitative point of view the situation of lack of thermal comfort in classrooms 202, 301 and 302 of block D of the architecture faculty and thus be able to verify the degree of compliance of these spaces with the international standard ASHRAE 55 2017. This was achieved through the analysis of a series of data obtained from these classrooms from the application of wind chill surveys and measurements of environmental variables directly related to thermal comfort by means of the appropriate instruments available to the UGC Bioclimatic Laboratory. Once the current situation of the classrooms was verified, the information was used as the main input for the development of the three-dimensional model DesingBuilder software, with which, through energy simulations, different improvement proposals were evaluated, which included both changes or implementation of materials as well as mechanical and passive systems that could contribute to the improvement of these classrooms according to thermal comfort and the air quality situation. Finally, it was concluded by analyzing the simulations and the economic feasibility in a hybrid proposal, resulting not only in an improvement in thermal comfort, but also in compliance with regulations.
