The role of facades is fundamental to determine the energy performance of a building. According to the properties of construction elements, the heat transfer towards the interior can be strategically controlled to avoid increases in energy demand by the cooling system. The development of insulating products can solve this problem. In Norte de Santander, Colombia, the thriving clay industry is based on raw material quality. This paper designs and validates the thermal behavior of two proposed ventilated bricks, called eco Design. The thermal validation was fulfilled using the ANSYS R16 software to simulate the transfer and heat fluxes according to shape and material. The best performance was achieved by an extruded process to determine the mechanical properties on a laboratory scale in different mixtures with technological additives. The results show that the ventilated air chamber can reduce the inner surface temperature up to 45.5 °F. Nevertheless, the strength of these new products is considerably reduced compared to traditional multi-perforated brick.

Currently, internal combustion engines face the challenge of reducing fuel consumption and reducing polluting emissions due to their significant impact on the environment. Therefore, it is necessary to use tools that allow us to evaluate the operating characteristics of this type of thermal machines. In the present investigation, the development of a virtual bench was proposed for the analysis of the behavior and performance characteristics of an internal combustion engine for use as a learning tool in higher education students. From the results obtained, it could be demonstrated that the pressure curves of the combustion chamber and the rate of heat release obtained by means of the virtual bench presented a high concordance with the experimental records. The maximum deviation obtained was 5% and 15% for the pressure curve and the heat release rate. Comparing the performance parameters of the brake specific fuel consumption of the engine and energy efficiency, a maximum deviation of 2.96% was shown compared to the real engine. In general, the virtual development bank can describe the behavior of the engine, allowing the characterization of physical phenomena, as well as evaluating the effect of auxiliary technologies such as turbo-compression systems.

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 p
