THERMAL COMFORT ANALYSIS BASED ON COMPUTER SIMULATIONS OF BUILDING ENVELOPE IN AN AUDITORIUM: A CASE STUDY IN BRASILIA -BRAZIL

Joao Walter Costa, Daniela Rocha, Caio Frederico E Silva

Abstract: This article focuses on the architectural design of Auditorium Dois Candangos, with the capacity for 120 users, which was built in 1962 by the architect Alcides da Rocha Miranda. This building is important due to its history and its modern architecture style. In 2015 it was reported by the users that this building had problems regarding thermal comfort and obsolete electric equipment. According to International Energy Agency and its guidelines towards a more efficient building envelope in hot climates, this study aimed at making thermal simulations in order to quantify the percentage of discomfort hours in this auditorium. To reach this goal, the software Design Builder was used to evaluate this historical auditorium with its original design and with modifications applying different insulated roofs and walls with distinct thermal and physical properties. Moreover, the lighting system and ventilations were also considered during simulations. These materials are being chosen according to the recommendations for the climate of Brasilia, Brazil. Solar radiation, wind, humidity and sky conditions are being taken into account. In conclusion, thermal simulations helped to determine the correct choice of the roof materials and its relation to the thermal comfort of this space. Therefore, it will be possible to create design guidelines for the optimization of the thermal comfort in such an important historical building situated in the University of Brasilia.
