Abstract: The sun is a historical premise for the city's quality of life, human health, and well-being. However, there is a discrepancy between what is produced by the construction industry in densely populated urban areas and the environmental comfort of their residents. With this in mind, the article investigated the behavior of the new metric for minimum sunlight exposure from ABNT NBR 15.215-3:2024 in verticalized neighborhoods of Curitiba/PR and Porto Alegre/RS, metropolises located in bioclimatic zones 1M (very cold with a moderate winter) and 2R (cold), respectively, where compliance with the requirement is mandatory due to the susceptibility to cold discomfort. Based on the construction potential of current master plans, it was observed that more restrictive urban planning parameters, as seen in Porto Alegre, greatly favor compliance with the standard at higher levels, even considering higher latitudes. In more permissive scenarios, such as in Curitiba, the metric alone does not provide definitive results, since it, in isolation, is not sufficient for a conclusive result on solar exposure, since most analyzed units would need to be subjected to thermal performance evaluation by NBR 15.575:2021 to verify compliance with Level I. Finally, authors concluded that aligning public policies, standardization, and market interests is necessary to ensure residents' comfort.
