TITLE:

ANALYSIS OF THERMAL COMFORT USING NATURAL VENTILATION AND ENERGY CONSUMPTION USING AIR CONDITIONING: The Case of the Faculty of Architecture and the Polytechnic School.

KEY WORDS:

Energy Efficiency, Natural Ventilation, Energy Consumption and Bioclimatic Architecture.

BIG AREA: Engenharias
AREA: Engenharia de Produção
SUMMARY:

Public educational buildings are among the most important types of buildings for research on sustainability, since, in addition to involving issues of environmental quality and energy efficiency, it points to the need to be a healthy, productive and, above all, educational environment. This research aimed to question the reasons for installing air conditioning equipment, even in adverse economic conditions and having knowledge of the negative environmental implications. To evaluate the thermal performance, 4 classrooms and a teacher's room in the building of the Faculty of Architecture of the Federal University of Bahia were investigated. In the study, the adequacy of the architectural design to the climate where it is inserted is verified, and the in loco measurements prove the potential of the ventilation that reaches the windows of the analyzed rooms. The assessments on thermal comfort from the interviews showed that 53% of the people felt comfortable. However, the precarious state of conservation of the frames was verified, which compromises the capture of natural ventilation, impairing
the proper operation of the frames and consequently the thermal performance of the building. To assess aspects of air conditioning consumption and energy management at the University, two of its units, the Polytechnic School and the Faculty of Architecture, were investigated. For this, a level I energy audit was carried out. Data on energy consumption between the years 2013 to 2018 were collected and analyzed. As a result of the study, the energy use indicator was found, which corresponds to 58 in the Polytechnic School. kWh/m2 /year and at the Faculty of Architecture of 40 kWh/m2 /year. As for the representation of energy consumption related to the use of air conditioning, 36% were observed in the Polytechnic School and 19% in the Faculty of Architecture. This research contributed to obtain energy efficiency indices, which can be used to compare with other universities and for UFBA itself. This study draws attention to the important educational role of the university in terms of reducing energy consumption, to the impact of managers' decision-making in improving the operation and maintenance of university buildings, to reducing the intensive use of artificial air conditioners. air, to the detriment of investment in projects that prioritize natural ventilation and good operating conditions for the frames.
