In Norte de Santander, Colombia, there is a ceramic cluster made up of 59 companies
dedicated to the production of construction materials derived from clay, a vernacular material
with a wide extraction potential in the region. Fired clay products in different hollow block
presentations represent 15% of industrial production, these construction pieces are low cost and
show a high demand in the local masonry market, therefore, their thermo-physical characteristics
largely build the thermal envelope of “Cucuteña”. This research comparatively evaluates the
thermal behavior of four types of ceramic blocks with different perforations, applying the finite
element method in thermal simulations that consider a conductivity of 0.407 W/m°C in the
ceramic to establish the influence of the shape on the temperature distribution and heat flow
profiles of each piece subjected to environmental conditions of a warm semi-arid climate, with
average maximum temperatures of 33 °C and an average maximum solar radiation of
796.8 Wh/m² under extreme climatic conditions in the city of San Jose de Cúcuta, Colombia.
The results of the study allow identifying the ceramic block of 6 rectangular holes as the product
that, due to its physical characteristics, presents a better alternative to be applied in constructions
that seek thermal efficiency.
