“…From BIM (Building Information Modeling) model, the file with the extension “rte” was exported directly from Revit to the Autodesk CFD 2021 software, through the “Add-Ins” ribbon ( Calautit et al, 2020 , Kim et al, 2020 ). This made it possible to model in 3D geometry in the Revit model in a parametric way; considering parameters and constructive interfaces in relation to the types of modular materials that make up the building as related to air speed ( Mousa et al, 2017 , Porras-Amores et al, 2019 , Calautit et al, 2020 ).…”

“…After assigning the appropriate material to each element and texture for a better approximation of the actual structure, the boundary conditions were configured according to the aforementioned wind angles, considering wind inflow and outflow ( Mousa et al, 2017 , Porras-Amores et al, 2019 , Calautit et al, 2020 ). To define air flow, a side surface of the generated external volume is selected as the normal direction in which the air is moving.…”

“…Porras et al [14] monitored a warehouse in-use underground building located in San Esteban de Gormaz (Spain), a location with an oceanic climate (Cfb). The volume of the construction is around 250 m 3 and is excavated to an average depth greater than 10 m. The construction has a tunnel, a cave and a ventilation chimney.…”

Thermal Monitoring and Simulation of Earthen Buildings. A Review

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.

“…Among these techniques, natural ventilation is widely studied numerically by using computational fluid dynamics (CFD). A study [7] examined natural ventilation for underground constructions in Spain, while another study [8] used a methodology and a case study for optimizing the natural ventilation of buildings by simulating the CFD wind environment in three different aspects, namely site planning, building shape, and building envelope. This study was conducted to propose ideas to remedy the inadequacy and weak synergy between the architectural design and technological analysis.…”

This study tested the effectiveness of some natural ventilation basic configurations for the thermal comfort of occupants in different local climates in Algeria. Due to the diverse Algerian climate, the study was performed during the mid-season period that includes three months of May, September, and October and the summer that includes the months of June, July, and August. The ventilation potential of the selected configurations was analysed through numerical simulation by using TRNSYS software coupled with COMIS aeraulic software. The results showed the significant contribution of natural chimney ventilation caused by a stairwell to improve occupant comfort. However; its integration requires a judicious and permanent inspection to control temperature decreases or overheating risks.
