Contribuições da integração BIM/BES para análises de desempenho térmico e conservação de livros em bibliotecas icônicas

Abstract

As a spreader of knowledge, universities should be practical examples of adapting to environmental constraints, building or intervening in their buildings without mischaracterizing them. Among these buildings are libraries, which must adapt the internal microclimate to their specificities, such as thermal performance and conservation of books, which require different parameters. The main objective of this research was to jointly analyze the thermal performance and conservation of books in iconic libraries from the BIM/BES integration, using the UFU Library at Campus Santa Mônica in Uberlândia/MG as an object of study, in addition to producing inferences about scenarios alternatives. The analyzed spaces have open plans with natural ventilation and environments that house a study area and book collection for consulting. The method adopted was the hygrothermal simulation based on the transfer of BIM/BES data, having as parameters for thermal performance and books conservation, respectively: the monthly operating temperature ranges of ASHRAE 55 (2020) and the isoperm method of Sebera (2001). Regarding the thermal performance, we concluded that the best scenario is the existing one, between 82.44% and 87.35% of the occupied periods throughout the year, and was considered more satisfied than the alternative scenario. For the conservation of books, we concluded that the current scenario is unsatisfactory since isoperms between 0.28 and 1, corresponding to paper longevity between 12.6 and 45 years. BIM/BES data transfer still needs to be more accurate in transferring geometry, thermal properties, and information such as use, occupancy, and scheduling.
