Evaluation of the thermal performance parameters of an outside wall made from lignocellulosic sand concrete and barley straws in hot and dry climatic zones

Influence of using clay block with increassed mass on energy performance of an office builidng in Nis

“…The decrement factor is defined as the ratio between amplitudes of the heat flow in internal and external surfaces (ratio of differences between maximum and minimum inside and outside surface temperatures) during its propagation for 24h. Time-lag and decrement factor are the primary metrics for existing material wall configurations [7,10,11,21] and for comparing new construction materials/wall systems [22][23][24][25], although with some variations in the definition for time-lag. Belhadj et al [23] defined time-lag including a period of investigation of 24h (if the time of occurrence of inner surface maximum temperature is lower than the time of occurrence of outside surface maximum temperature, time-lag is the sum of the difference of occurrences of the temperatures and period of 24h; if the two temperatures are identical, time-lag equals the period of 24h; in all other cases it is the difference between the time of occurrence of the two surface temperatures).…”

“…A similar definition had been implemented in [25] but with the addition of 24h period on difference of time of occurrence of the maximum inside and outside surface temperatures in all cases. In [24] average time-lag is introduced as the average between maximum time-lag (difference between the time of occurrence of the maximum inside and outside surface temperatures) and minimum time-lag (difference between the time of occurrence of the minimum inside and outside surface temperatures) for the construction over the same time period. L.Y.…”

“…The values of time-lag and decrement factor defined as in [23], as primary indicators of thermal inertia, during winter and summer weeks for the modelled building are given in table 5. Their change with unit mass is shown in figure 4 and correlates well with [7] and [24]. It should be noted that these indicators have been calculated by using outputs of the simulation and do not represent the values from the standardized procedure [20] but it can be helpful to see their variation when a building is exposed to transient outside conditions and considering the building layout and location.…”

Reuse of banana fiber and peanut shells for the design of new prefabricated products for buildings

“…One of the ways to contribute to the sustainable development of nations, especially those that rely heavily on the primary economy, is through the use of agricultural wastes by a recycling process, to convert them into a source of raw material for the production of construction materials that satisfy quality parameters (Pinto et al, 2012). In this regard, the usage of lignocellulosic waste in eco-friendly composites of several kinds is a valid alternative (Belhadj et al, 2020;Jami et al, 2019). In cases where the characterization and dosage are optimal, even an improvement of some properties can be achieved when comparing with the reference materials (Thongtha et al, 2014).…”
