Adequate natural ventilation not only contributes to indoor air quality but also to occupants' productivity, thanks to improved thermal comfort. When this ventilation is promoted through active strategies, it is crucial to adopt systems with maximum energy efficiency. Thus, this scientific article investigates thermal performance in residential buildings, focusing on the opening rate for natural ventilation. In addition to a bibliometric analysis focused on mapping the relationship between the standards, the research conducted a comparison among NBR 15.575 and municipal regulations of Brazilian capitals, assessing to what extent local codes meet the standards established by the national norm. The main objective is to identify similarities and differences in thermal performance guidelines, providing a comprehensive comparative analysis between the technical standard and local regulations of Brazilian capitals related to natural ventilation in buildings. The analysis revealed a lack of research linking the two topics and also consistent adherence in many local codes, but also specific gaps. Difficulty accessing codes was identified as a challenge, and some recommendations were made to ensure compliance.
