Patrones constructivos de enfriamiento pasivo para mampostería cerámica de bajo costo

Abstract

The present research studies the thermal performance of a new masonry enclosure configuration that generates a mixed system by employing 2 types of traditional hollow ceramic block from the nortesantandereana industry, the 100mm thick H10 block and the 150mm thick H15 block, to produce modulations that incorporate thermal cooling strategies by introducing air renewal channels and a discontinuous initial surface that allows solar control by shading, inhibition characteristics and dissipation of accumulated energy that mitigate thermal transmittance under high temperature environmental conditions. Thermal simulations are applied to analyze profiles of temperature distribution and heat flow in 6 building systems with passive cooling patterns in the form and function of the exterior surfaces. For the analysis, the models are exposed to the most extreme climatic conditions of a hot semi-arid climate taking as reference the periods of highest temperature and solar radiation in Cúcuta, Colombia to determine the thermal performance of the different configurations and evaluate the feasibility of the solutions. The results show that the implementation of passive cooling strategies based on low-cost ceramic products in masonry systems is an efficient and economical alternative that favors the thermal performance of the envelope, an especially important aspect in extreme hot climates.
