Comparison of future weather files for Brazilian cities

Abstract

There is an increasing interest from academia, government, and private companies in future weather generation to predict new climate realities and prepare our assets for resilience and adaptability. In the built environment, practitioners have evolved by building simulation weather files with new tools to implement updated climate change predictions. Thus, this paper focuses on testing and understanding Brazilian climate change using the tool Future Weather Generator. Simulations under different Shared Socioeconomic Pathways were carried out, and future climate variables were discussed. This paper is part of an ongoing effort to understand how future climates may impact buildings, including comfort and energy consumption. In conclusion, the climate in Brazil is expected to become warmer in all cities, although there is a higher dry bulb temperature increase in the centre-west and northern regions. As for wind speed, relative humidity and radiation, different trends were observed in each climate. Brazil must adapt to each new climate reality and focus on efforts to provide adaptability and resilience.
