Conforto e desempenho térmico nas edificações do novo centro de pesquisas da Petrobras no Rio de Janeiro

Abstract: 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 natur… Show more

“…For naturally ventilated internal spaces, dry bulb temperature, relative humidity and mean radiant temperature extracted from the simulations' results are used to calculate TE* for each hour, which is assessed in relation to the comfort zone. Comparing the TE* figures calculated for each hour of the reference year with the limits of the adaptive comfort zone created for the climate of Rio de Janeiro, one can observe that 50% of occupation time are in accordance with the acceptable thermal comfort conditions [19]. In other words, in a hypothetical scenario where the internal conditions are equivalent to the calculated TE*(for the external climatic conditions), comfort would be obtained for 50% of the occupied hours, which was then considered as a reference for the performance of the naturally ventilated environments.…”

“…Looking at the yearly percentage of comfort hours in the naturally ventilated environments, the highest performance was found in the changing rooms in the Operational Support Building, featuring approximately 60% of the yearly occupation hours within comfort conditions (considering the hours found in "cold" conditions are insignificant) (see table 9). In addition, it was estimated that the addition of the mechanical system would increment the number of air changes per hour could raise the hours in comfort to 75% (an increase of 65% comparatively to its performance before the implementation of the initial architectural modifications) [19]. On the other hand, the lowest performance was in the kitchen of the same building marking 51% of hours in comfort (see table 10).…”

“…O crescente aumento na demanda de energia elétrica se depara com a limitação dos recursos naturais existentes. Com isso, torna-se inevitável que os setores sociais se preocupem em desenvolver suas atividades de forma mais eficiente e sustentável, com menos impactos ao meio ambiente (BITTENCOURT et al, 2007;MARCONDES et al, 2010;ALTOÉ;OLIVEIRA FILHO;CARLO, 2012;BRUGNERA et al, 2019).…”

“…Diante dessa realidade, pensando no conforto térmico humano dentro de edificações, atrelado à economia de energia, estudos vêm sendo realizados, bem como práticas menos degradantes ou de baixo consumo energético estão sendo adotadas com maior frequência, para o controle de temperatura nesses ambientes com eficiência energética (MARCONDES et al, 2010;KRÜGER;MORI, 2012;RUPP;GHISI, 2013;FAZLIKHANI;GOUDARZI;SOLGI, 2017;BRUGNERA et al, 2019).…”

“…Energyefficient buildings with special designs such as orientation, insulation and windows are being appropriately adapted to withstand severe weather conditions (HOLOPAINEN, 2017). Natural ventilation (MARCONDES et al, 2010) and natural light (FONSECA; DIDONE; PEREIRA, 2012) also play an important role in energy saving. Additionally, one can have buildings with walls composed by different materials (SPECHT et al, 2010) and the consideration of daylight when evaluating buildings regarding energy performance PEREIRA, 2010).…”
