Os sistemas construtivos com terra carecem de normas brasileiras específicas para desempenho térmico. Logo, o objetivo foi realizar um estudo bibliométrico sobre a condutividade térmica do solo-cimento e as demais propriedades físicas que a afetam. Executou-se um levantamento de dados com foco em dois sistemas construtivos: blocos de terra comprimido (BTC) e taipa de pilão. Constatou-se um intervalo para condutividade térmica variando entre 0,7 a 1,1 (W/m.K). O parâmetro de engenharia que exerceu maior influência foi a forma de moldagem do material, que acarreta em mudanças da massa específica e da capacidade térmica do componente construtivo.

Thermal Monitoring and Simulation of Earthen Buildings. A Review

2021

Since ancient times, raw earth has been used worldwide as a construction material. Today, it is well known for its good environmental properties of recyclability and low embodied energy along the production process. Earthen walls regulate the interior temperature of the buildings, providing comfortable temperatures with a very low carbon footprint. As a result of those advantages, earthen building techniques have been revived and used for contemporary architecture. The aim of this paper is to review the state of the art about the thermal behaviour of earthen building, including all the monitoring and simulation analysis of real earthen constructions up to now. The paper presents the different earthen techniques known nowadays, analysing the most important thermal parameters and the thermal comfort achieved with each technique. Regardless the wide differences among the analyzed cases, the authors conclude that earth building is a suitable solution in hot and arid climates, since it preserves the indoor temperature within the thermal comfort limits most part of the time without any active system.

“…Como sustento de esta afirmación, el marco actual de investigación del BT se ha centrado en estudios sobre sus propiedades mecánicas (Gandia, Gomes, Corrêa, Rodrigues y Mendes, 2019;Mahmood, Habeeb y Al-Jumaili, 2019), térmicas (Mosquera, Canas, Cid-Falceto y Marcos, 2014;Molar-Orozco, Velázquez-Lozano y Vázquez-Jimánez, 2020;Miloudi et al, 2019;Wati, Bidoung, Damfeu, y Meukam, 2020) y de durabilidad (Fernandes, Peixoto, Mateus y Gervásio, 2019; Lavie Arsène, Frédéric y Nathalie, 2020; Jové Sandoval, Muñoz de la Calle y Pahíno Rodríguez, 2011). Otros avalan la utilización del BT argumentando aspectos económicos, baja toxicidad e, incluso, como producto que favorece la calidad del aire interior (Fernandes et al, 2019).…”

Although earth block construction (EB) is supported by numerous scientific works, there is a lack of confidence in its constructive viability, aggravated by the lack of specific technical training. In view of this uncertainty, which is widespread in Spain, it is necessary to provide well-founded technical responses. This article, considering these aspects, presents the design and validation of a tool to assess the constructive viability of EB. For this purpose, 29 case studies are chosen in Spain, which establish the constructive use determinations and indicators to assess a degree of technical suitability. This parameter, as a result of the proposed tool, acts as a support for decision-making, the improvement of the design and, the efficiency of the solutions that use EB. It concludes by validating the tool, demonstrating its reliability and adaptability to any situation. Finally, the case analysis shows how the quality of the product combined with adverse external conditions, even with correct construction designs, defines a common situation where the degree of suitability of the solution is reduced. Therefore, it is also necessary to demand products with guarantees and prescriptions that ensure and offer sufficient technical safety.
