Bioclimatic   zoning   is   an   important   toolto   provide   subsidies   for   structuring   thermal performance  regulations  and  energy  efficiency  codes  of  buildings.  However,  a  consistent methodology for developing zoning proposals still needs to be discussed. This article aims to evaluate  the  applicability  of  the  factorial  design  as  a  method  for  the  characterization  of bioclimatic  zones.  For  this,  the  factorial  experiment  was  used  to  analyze  the  variables  of influence   on   the   thermal   performance   of   residential   buildings   naturally   ventilated   in different  Brazilian  climates.  Thermal  performance  simulations  were  performed  from  the factorial,  and  the  cities  analyzed  were  grouped  according  to  the  performance  regarding thermal  comfort  and  influence  variables.  In  general,  the  main  variables  of  influence  the thermal  comfort  of  the  buildings  are  the  solar  absorbance  of  the  wrap,  the  thermal transmittance   of   the   roofs   and   the   ventilation.   For   milder   climates,   the   thermal transmittance  of  the  walls  also  had  an  influence,  while  the  thermal  capacity  of  the  walls influenced the transition climates. Among the sampled localities, it is possible to recognize four patterns of behavior regarding thermal comfort and the variables of influence, enabling the  grouping of  cities.  Four  bioclimatic  zones  were  identified  and  subdivided  according  to local ventilation needs. The originality of this work is in the proposal of characterization of bioclimatic zones based on an adaptive comfort model. More than one model of multifamily buildings was considered in a factorial analysis.
