Item A Review on Numerical Modeling of the Hygrothermal Behavior of Building Envelopes Incorporating Phase Change Materials(Multidisciplinary Digital Publishing Institute (MDPI), 2023-12) Sawadogo, Mohamed; Godin, Alexandre; Duquesne, Marie; Hamami, Ameur El Amine; Belarbi, RafikBuildings are submitted to various external and internal solicitations that could affect its energy performance. Among these solicitations, temperature and moisture play a crucial role and could irrevocably affect the comfort of the occupants and the indoor air quality of the living environment. To assess the impact of the solicitation on building performance, a precise modeling of the heat, air, and moisture transfer phenomenon is necessary. This work proposes an extensive review of the hygrothermal models for building envelopes. The different models are divided into nodal and HAM techniques for heat, air, and moisture (HAM) transfer models. The HAM approach has been classified based on four driving potentials: moisture content, relative humidity, capillary pressure, and vapor pressure. Phase change materials (PCMs), alongside hygroscopic materials, enhance building thermal capacity and energy efficiency. There are various approaches to studying phase changes, with enthalpy-based and heat capacity approaches being the most popular. Building performance can be improved by combining PCM thermal inertia with hygroscopic moisture management. This review has exhibited the need for numerical models that address phase change and moisture behavior in these hybrid materials, capable of controlling temperature and humidity. © 2023 by the authors.Item Comprehensive Review of Innovative Materials for Sustainable Buildings’ Energy Performance(Multidisciplinary Digital Publishing Institute (MDPI), 2023-11) Nasr, Yara; El Zakhem, Henri; Hamami, Ameur El Amine; El Bachawati, Makram; Belarbi, RafikThe building sector, one of the most energy-consuming, is among the most current topics due to the maturing concerns about the anthropogenic factor’s impact on CO2 quantities in the atmosphere and its association with global temperature rise. Using sustainable building materials is a promising alternative in building envelope applications to improve in-use energy efficiency. These materials, having a low environmental impact, the advantage of being renewable, and low embodied energy, contribute to global sustainability. This comprehensive literature review presents a broad overview of these materials’ hygrothermal characteristics, thermal performance, and energy use. The main goal is to compile the most important research findings on these materials’ capabilities for building construction and their contributions and effects on energy performance and thermal insulation. © 2023 by the authors.Item High-Volume Recycled Waste Glass Powder Cement-Based Materials: Role of Glass Powder Granularity(Multidisciplinary Digital Publishing Institute (MDPI), 2023-07) Younsi, Akli; Mahi, Mohammed Amar; Hamami, Ameur El Amine; Belarbi, Rafik; Bastidas-Arteaga, EmilioThe use of recycled waste glass powder (RWGP) as a partial substitute for cement in cement-based materials offers a promising solution for reducing environmental impact and promoting sustainable waste management practices. An experimental study was conducted on a reference material made with Portland-limestone cement CEMII/A-LL42.5R and three other materials containing 50 wt% RWGP with different mean diameters, d50: 16, 18, and 25 µm. The main objective was to analyze the role of RWGP granularity in the short- and medium-term properties of the cement-based materials. The results showed that coarser RWGP granularity led to an increase in fluidity and Portlandite content, while water demand and mechanical properties decreased. However, the range of RWGP granularities tested did not significantly affect the initial setting time, fresh and dry density, hydration temperature, and water porosity. These findings suggest that the choice of RWGP granularity should depend on the desired properties of the cement-based material. © 2023 by the authors.Item Investigation of eco-friendly and economic shape-stabilized composites for building walls and thermal comfort(Elsevier Ltd, 2022-03-01) Sawadogo, Mohamed; Godin, Alexandre; Duquesne, Marie; Lacroix, Elodie; Veillère, Amélie; Hamami, Ameur El Amine; Belarbi, RafikItem The Thermal and Mechanical Behaviour of Wood-PLA Composites Processed by Additive Manufacturing for Building Insulation(Multidisciplinary Digital Publishing Institute (MDPI), 2023-07) Bahar, Anis; Hamami, Ameur El Amine; Benmahiddine, Ferhat; Belhabib, Sofiane; Belarbi, Rafik; Guessasma, SofianeThis study was aimed at considering the potential of wood-based composites processed using additive manufacturing as insulators in the building sector. A polylactic acid blend with 30% wood particles was used as a feedstock material in fused filament technology. Its thermal and mechanical properties were determined for various processing conditions, including printing temperature and infill rate. The results showed a minor contraction in its tensile performance as a result of the printing process. The printing temperature had a negligible effect on its stiffness and a limited influence on the other engineering constants, such as the tensile strength and ultimate stress. The thermal properties of printed structures have been found to significantly depend on the infill rate. Although the tested 3D printed wood-PLA material exhibited good thermal properties, which were tuneable using the printing conditions, its performance was still 38% to 57% lower compared to insulators such as the glass wool of the synthetic foams used in the building sector. © 2023 by the authors.
