Resumo

O estudo investiga a eficiência térmica e o conforto interno das fachadas verdes em habitações de interesse social localizadas em Santa Maria, Brasil. Ao longo de um ano, seis unidades habitacionais foram monitoradas para avaliar o desempenho durante o verão, sendo que cinco unidades incorporaram fachadas verdes e uma serviu como unidade de controle sem vegetação. A coleta de dados concentrou-se em parâmetros climáticos, como temperatura do ar e umidade relativa, registrados a cada 15 minutos por meio de sensores térmicos e imagens termográficas. Os resultados revelam que as fachadas verdes melhoraram o desempenho térmico, reduzindo as temperaturas superficiais e aprimorando o conforto térmico. A diferença máxima de temperatura observada entre as unidades com fachadas verdes e a de controle atingiu 12,6°C. As imagens termográficas validaram visualmente esses resultados, confirmando o efeito de resfriamento. As análises da Temperatura Fisiologicamente Equivalente (PET) demonstraram o aumento do conforto térmico nas unidades com fachada verde, com a maior diferença de PET registrada em 6,5°C no dia 24 de fevereiro. A pesquisa reforça a importância da adoção dessa estratégia em habitações sociais para mitigar desafios ambientais, melhorar a eficiência energética e promover o bem-estar em áreas urbanas
