Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Since buildings are associated with a large share of energy consumption, their thermal insulation is a paramount parameter. This can be achieved by integrating eco-friendly materials into building envelopes to mitigate energy consumption. In this context, the proposed study aims to numerically examine the thermal insulation and energy performance of an eco-friendly insulated wall incorporating mycelium and facing south in Marrakech city (Southwestern Morocco) using 2D CFD simulations. The computations are carried out via the CFD software Ansys/Fluent 19.0. The findings were compared to those for the no-insulated wall deemed as benchmark (case #1) in terms of temperatures, transmission loads and the insulation thickness effect. As expected, it was confirmed that the insulated mycelium-based wall (case #2) is more efficient than the uninsulated wall (case #1).First, the time lag and the decrement factor are studied to assess the dynamic thermal behavior of a multi-layer wall insulated with the mycelium. Thereby, based on a life cycle cost analysis (LCCA), the optimum thickness of the mycelium has been turned out to be 0.08 m, and energy saving improved by 87.4% in winter and 55.9% in summer. Besides, in the last time (t = 72h) of simulation, the inner surface temperature decreased by about 4°C and increased by about 1°C during summer and winter days, respectively. Further, the thickness effect on the energy coating increased from 56% to 93% (~1.7 fold).Through these results, it can be concluded that the proposed design could be an appropriate solution for dry and hot semi-arid or even arid climates.
