The concept of performance is of paramount importance when it comes to meeting user
requirements in civil construction. This is because a building with satisfactory performance is
one that meets the objectives and minimum requirements for which it was designed. Therefore,
worrying about performance when designing a building is primarily to think about the well-
being of the inhabitants. Thus, the thermo-acoustic comfort of a property capable of meeting the minimum performance requirements significantly contributes to the owner's satisfaction,
bringing benefits even for their physical and mental health. In this context, the ABNT NBR
15575:2013 performance standard was developed in an attempt to establish minimum
performance criteria that buildings must meet, aiming to provide more safety, comfort and
economy to the user, in addition to being an important means to measure the level of
performance that the building is capable of achieving. In the present work, we sought to analyze
the thermo-acoustic comfort of a building built in structural masonry with the use of ceramic
blocks in Palmas/TO. The result obtained from the study was that the building did not present
the minimum performance required by the standard in any of the two criteria analyzed. As for
thermal comfort, the maximum internal temperature on the day of verification was 33.4 °C
while the maximum external temperature was 33.0 °C. For acoustic comfort, the measured
DnT,w was 40 dB, while the performance standard determines it to be at least 45 dB for the
situation analyzed. It is concluded, therefore, that there is a need to seek ways to improve the
performance and comfort of buildings in general, dedicating greater attention to this situation
at the time of designing the property.
