Resumo

O nível de hermeticidade ao ar de uma habitação influencia diretamente as condições térmicas, acústicas e de salubridade que se apresentam em seu interior. Diante da ausência de estudos que abordem o tema no âmbito local, a presente pesquisa teve como objetivo identificar o valor e os fatores que condicionam o nível de hermeticidade de habitações precárias construídas em assentamentos informais da cidade de Lima. Por meio do método da "porta ventiladora" (blower door), realizaram-se medições em cinco habitações, que evidenciaram taxas de renovação de ar entre 280 e 40 ACH (renovações de ar por hora) a uma pressão diferencial de 50 pascals — valores consideravelmente elevados, que refletem a baixa hermeticidade dessas edificações. Estes resultados constituem uma primeira abordagem empírica sobre a hermeticidade ao ar em habitações precárias, ao fornecerem dados preliminares úteis para a análise do conforto térmico em contextos de alta vulnerabilidade urbana.
