Considering the opportunities presented by porosity to increase the thermal resistance of ceramic materials, this study is articulated from the design framework to add thermally efficient properties to fired clay blocks in the generation of low-cost construction solutions for Norte de Santander, Colombia a warm tropical climate. The research uses as a technological additive sawdust to generate porosity to a ceramic product that presents morphological modifications in the internal partitions interrupting the conductance by thermal bridge, and evaluates comparatively the influence of the increase of thickness in the piece and the addition of internal walls as techniques to reduce heat transmission. The methodology is developed from thermal simulations in ANSYS R16 software to determine temperature distribution and heat flow profiles in a traditional block-type piece and three samples with dissipative forms in a composition of 5 % sawdust and 95% clay, taking the specimens with the best performance to execute physical-mechanical analyses implementing Colombian Technical Standard 4017. The results present an opportunity for development in the dissipative forms of the partitions and in the implementation of residual pore forming substitutes, rescuing characteristics of a traditional piece to configure more efficient construction units.
