Thermal comfort and performance in the buildings of the new research centre of Petrobras in Rio de Janeiro

This paper presents the a study of the thermal performance of the new Petrobras research centre, CENPES II, in Rio Janeiro, including free running and air-conditioned buildings. The architectural design was the subject of a national competition in 2004, encompassing over 100.000m2 and ten buildings....

This paper presents the a study of the thermal performance of the new Petrobras research centre, CENPES II, in Rio Janeiro, including free running and air-conditioned buildings. The architectural design was the subject of a national competition in 2004, encompassing over 100.000m2 and ten buildings. According to the design brief, four buildings should be naturally ventilated, whilst six had to be either air-conditioned, due to specific occupation requirements. In the case of naturally ventilated buildings, adaptive comfort was applied as performance criterion, and the environmental assessments were supported by advanced simulation tools. In most of the spaces within the free-running buildings the performance assessments showed environments with similar conditions to the exterior. Considering the working spaces pre-determined to be air-conditioned, the potential for natural ventilation in the working spaces reached 30% of occupation hours, justifying the case for the mixed-mode strategy. Este artigo apresenta um estudo do desempenho térmico dos edifícios do novo centro de pesquisas da Petrobras, CENPES II, no Rio de Janeiro, incluindo edifícios naturalmente ventilados e edifícios condicionados artificialmente. O projeto foi objeto de um concurso nacional em 2004, com um programa de 100.000m2 e dez edifícios. O edital propôs quatro edifícios naturalmente ventilados e outros seis artificialmente climatizados, pelas exigências do uso e especificidades da função. Nos edifícios com ventilação natural foi aplicado um modelo adaptativo de conforto térmico e as avaliações de desempenho foram realizadas com o suporte de ferramentas avançadas de simulação computacional. Na maioria dos ambientes com ventilação natural encontrou-se condições similares ao clima externo à sombra, comprovando a adequação da arquitetura ao clima. Nos ambientes de trabalho em que a climatização artificial foi colocada como premissa foi identificado, inicialmente, um potencial de 30% de ventilação natural durante as horas de ocupação, justificando a verificação das possibilidades do modo-misto de climatização.
