• Abstract:

  Given the worsening of climate change and intense heat waves in the Amazon, it is necessary to reevaluate the thermal comfort criteria adopted in Manaus. This study analyzes, through bioclimatic modeling, the effectiveness of passive natural ventilation strategies, based on the year 2023, the hottest of the decade. The methodology uses the software Climate Consultant 6.0 and Analysis Bio 2.2 with data from INMET, SBMN, and SBEG, seeking to identify passive cooling solutions under extreme conditions. The results indicate that natural ventilation, combined with shading, can reduce air conditioning use by up to 30%, provided that the openings are properly sized and integrated into the urban fabric. This is the first study using extreme 2023 data for bioclimatic modeling in Manaus. The comparison between the software programs reveals distinct approaches, reinforcing the importance of methodological adjustments to the local context. The research provides practical insights for architectural design, promoting thermal comfort and reducing the need for artificial climate control.
