Abstract

RAMOS, Ana Lin  and  BAUER, Elton. Study of the facade degradation agents associated with temperature and driving rain in different Brazilian bioclimatic zones. Rev. ALCONPAT [online]. 2022, vol.12, n.2, pp.248-262.  Epub Apr 29, 2024. ISSN 2007-6835.  https://doi.org/10.21041/ra.v12i2.560.

Therefore, the aim is to study the conditions of exposure to these degradation agents in buildings located in different Brazilian bioclimatic zones. Knowing the action of weathering is essential to understand the facades degradation. For this purpose, eight cities were selected: Curitiba, Santa Maria, Florianópolis, Brasília, Niterói, Goiânia, Picos and Belém. A model building was defined for hygrothermal simulation to assess total radiation, temperature range, thermal shock, intensity index temperature and driving rain. As a result, zones of critical conditions are identified, providing exposure rankings. For temperature agents and directed rain, the most exposed cities are Goiânia-GO and Belém-PA, respectively. Finally, the mildest exposure zones are Belém-PA for temperature agent and Niterói-RJ for driving rain.

Keywords : degradation; facades; ceramic coating; bioclimatic zones; temperature.
