ABSTRACT
Recycling is an alternative
for preserving historical heritage buildings. Through such process, buildings
are occupied by new usages that assure they are not abandoned. However,
conservation issues, like pathological manifestations by filamentous fungi, are
common even in buildings receiving new uses. Thus, it is extremely important to
know the microclimate behavior of these buildings and analyze if there are
usages that favor the appearance of filamentous fungi or not. This study aims
to verify if new usages modify the microclimate in historical buildings and if
such possible change favors the appearance of pathological manifestations by
filamentous fungi in some specific use. To achieve the
results, three buildings that have gone through
recycling processes were chosen in the city of Pelotas, in Southernmost Brazil.
The city possesses a large number of buildings with historical value and its
climate conditions are propitious for appearance of filamentous fungi. For 12
months, microclimate was monitored, the environments modus operandi was
characterized and there was a survey on the pathological manifestations by
filamentous fungi in the three buildings with two different uses:
administration offices and exhibition rooms. Conclusion was that usages that
allow natural ventilation and lighting favor conservation, which is what
happens in the ones used as administration offices. Besides that, it was
noticed that the construction system also influences, since buildings with a
high cellar that is being used did not present filamentous fungi, which also
shows the influence of ascending humidity on the appearance of such
pathological manifestations.
