Resumo
Whereas the understanding that comfort is basic to the realization of all prerequisite and any built space and the challenge of re-thinking the architecture as a tool capable of planning the built environment respecting regional and cultural particularities, this research aimed to investigation the thermal performance of the Trindade Island Scientific Station (ECIT) with natural ventilation as the main condition for generating passive thermal comfort. Based on an adaptive thermal comfort approach was adopted a methodology based on four distinct steps investigation the thermal performance. The first step was based on a literature survey, seeking, and a better understanding on the subject of comfort, the choice of the best procedure for evaluating the performance of the built environment on this aspect. The second step consisted of the characterization of the object of study, observation of its use pattern, its constructive system and the characteristics of the surroundings. Then we proceeded to conduct field measurements and computer simulations to evaluate its thermal performance. Finally, simulations were performed considering a proposed local intervention seeking performance improvements found for playback of construction technique in difficult to access locations. Based on this study, it can be stated that the ECIT showed good thermal performance for naturally ventilated rooms, but it has been found that rooms with poor thermal performance were those with the smallest aperture areas and worst natural ventilation. It was verified that after the intervention a significant reduction of the intensity of thermal discomfort to the analyzed environment was detected. It is understood that the diagnosis made on ECIT contribute to enhance future planning decisions and to detect thermal comfort issues that affect directly the performance of the building. Thus, the search for the understanding that thermal comfort should be constant in relation to the built environment, it is understood that the analysis can facilitate the insertion of effective strategies for improvement of the construction technique used in ECIT and to confirm the potential use of natural ventilation for comfort.
