Abstract
Filamentous fungi are important agents of deterioration, able to result in actual losses in many construction materials. Relative humidity (RH), surface temperature, and nutrient availability, in addition to the characteristics of substrates such as hygroscopicity and pH are critical factors in the development of related pathological manifestations. This study presents an analysis of the microclimate in a nineteenth-century historic building in the city of Pelotas, Southern Brazil, in order to verify the probability of recurrence of filamentous fungi. Eight sensors were installed in different indoor environments, for monitoring RH and temperature values in one year. The data analysis shows that, regarding microclimate, the recurrence of fungi is possible due to exposure of walls with high values of RH (above 70 %) for a prolonged period. The development of this type of analysis intended to indicate strategies to control the filamentous fungi growth from the microclimate control and ongoing maintenance of the historic building materials.
