SUMMARY:

Climate change represents one of the greatest global challenges of our time, highlighting the importance of design decisions in mitigating its impacts. In this context, international environmental agreements have encouraged the development of sustainable strategies, promoting the reduction of adverse environmental impacts across various sectors and directly influencing the planning and conception of architectural projects. In Brazil, a prominent solution is the application of brise-soleils as solar control elements on building openings. In this Regard, it is evidente that color can impact their termal performance. Thus, the objective of this study is to analyze the influence of colors in metallic brise-soleils on the variation of their surface temperatures within the climatic context of the Federal District (FD). Based on an analysis of existing protocols and the selection of the northwest façade of Escola Verde, located in the Administrative Region of Riacho Fundo in DF, a thermographic analyses were conducted using infrared thermography over seven months (march to september 2024) as a case study. The data were analyzed through correlations and convergences to understand the relation between surface temperature and the hues and brightness levels of the colors present on the building’s metallic brise-soleils. The tabulated data reveal the predominance of blue tones getting 62% of the highest temperatures, the thermal stability of yellow tones corresponding to 59% of the lowest temperatures, and the intermediate behavior of red tones representing 11%. Regarding brightness, 55% high-luminosity metallic brise-soleils were more effective at reflecting heat, while 59% of metallic brise-soleils with highest radiation absorption rates were those with low luminosity. In this context, clear correlations between hue, brightness, and the surface temperatures of metallic brise-soleils emerge as a strategy to support design decisions.
