Physical properties of straw bale and its effect on building energy conservation and carbon emissions in different climatic regions of Iran

Low-tech passive solar design concepts and bio-based material solutions for reducing life cycle GHG emissions of buildings – Life cycle assessment of regenerative design strategies (2/2)

“…An important note to add is that the scienti c literature further suggests that the use of bio-based materials in building envelopes (such as hempcrete or straw) can result in less energy consumption for air-conditioning because of their excellent thermal and moisture buffering capacity [20,43] 3.5 Limitations this study In a rst step we analyzed the life cycle GHG emissions (GWP indicator) for both buildings, which showed that material-related, embodied environmental impacts are most important, albeit with very different outcomes. For the massive brick be2226 building, focusing on longevity and exibility in use, embodied emissions are around 2.4 times higher than for the mass timber SolarHouse, focusing on circularity and the use of bio-based materials.…”

Artificial Intelligence Approach for Bio-Based Materials’ Characterization and Explanation

“…Overall, the introduction of plant fibers in concrete has the potential to improve the sustainability and resilience of construction materials while also providing economic benefits through reduced maintenance and repair costs according to M. Charai et al, and Y. Shang et al [10,11]. M. Mehravar et al have carried out research on saving energy [12]. A recent study showed that the use of straw bales as a building material reduces construction energy consumption and the embodied carbon emissions were reduced by 93.12% and 76%, respectively.…”

Numerical modeling of conjugate heat transfer through concrete hollow bricks

“…Several studies assessed the value of using insulating materials to improve buildings' thermal efficiency. [18][19][20][21][22][23][24][25][26][27][28] Li et al 18 conducted a computational investigation on the effect of the thermal efficiency of sintered hollow bricks filled with insulation materials. The findings show that internal surface heat flux is lowest when expanded polystyrene (EPS) materials are placed in the external brick cavities and the degradation rate is 5.3%-10.9% greater when EPS is placed in the internal cavities.…”

“…The results demonstrate that the hollow blocks' low emissivity will contribute significantly to a reduction in construction energy use. Several studies assessed the value of using insulating materials to improve buildings' thermal efficiency 18–28 . Li et al 18 conducted a computational investigation on the effect of the thermal efficiency of sintered hollow bricks filled with insulation materials.…”
