Analysis of the availability and autonomy of daylight in indoor spaces of three cities in São Paulo within Bioclimatic Zone 3B.

Abstract

This study analyzes the availability and autonomy of daylight in indoor spaces in Campinas, Bauru, and São Carlos, three cities in São Paulo classified within Bioclimatic Zone 3B according to the ABNT standard (2024a). These cities have similar climatic data, and this study complements the Brazilian Bioclimatic Zoning with natural lighting data. The methodology was based on computational simulations using Climate Studio software, considering two periods of the year: warm (September to March) and cold (March to September). The results, presented through graphs and visual maps, include metrics such as average illuminance, UDI, and ASE 1000/250. The analyses revealed similarities in daylight distribution, with excessive light being the main concern. The conclusions highlight the importance of specific strategies for each opening orientation to optimize direct sunlight control and address the particularities of these cities.
