Abstract

The cooked block H10 of dimensions L: 300 mm, A: 100 mm, H: 200 mm and 6 rectangular cavities is the leading product of the ceramic masonry industry in the Norte de Santander region, this research takes as its starting point its Initial characteristics: dimension, shape and weight to perform a morphological exploration of the geometry of the internal cells in this constructive unit in search of the optimization of its thermal properties to obtain insulation in high temperatures of 33 ° C characteristic of warm climates, a study framed in the context of clay as a vernacular material under the environmental conditions of Cúcuta city, Colombia, structuring an exploration that articulates strategies towards the development of energy efficiency. A finite element method (FEM) was applied in ANSYS R16 simulation software to establish comparatively the thermal behavior in the standard product of Form-A and 3 variations in the type of internal cells in the same thickness of 100mm and 6 horizontal cavities, applied analysis of temperature distribution and heat flow in a traditional masonry building system with equal heat incidence in the initial surface; the results allow to compare the final temperature derived from the morphologies in the Form-B, Form-C and Form-D, from the analysis is derived 54.948 W/m2 in the heat flow on the partitions of the Form-C as the geometry with better performance, achieving a decrease in thermal energy of 0.981 ° C in the final surface of the enclosure related to Form-A this procedure links up the variables that favor the dissipation of energy from -the form-, a passive technique that can be applied from the industrial process to reduce the percentages of heat accumulated by enclosures in ceramics, displaying an opportunity to add value to low-cost products.
