Abstract: The potential of natural materials is becoming more and more important as concerns about the environmental impact and energy efficiency of the construction sector grow. Incorporating waste from fiber sub-products seems like a wise choice, in line with the circular economy model. Despite the fact that date palm materials have been extensively researched and developed for use in modern buildings, the potential of using date palm fibers has not been widely explored. This research intends to examine how date palm fibers thermal insulation affects a building’s thermal efficiency in an Atlantic climate. An analysis using a numerical simulation using the TRNSYS software is conducted to determine the effect of this passive approach on cooling/heating loads and indoor comfort. This technique is measured against a hypothetical reference case of homemade traditional building materials without thermal insulation. The results show that insulation with date palm fiber materials has a significant effect on the indoor air temperature and the cooling and heating loads of the house. In comparison to the reference case, the studied house achieves better comfort conditions when thermal insulation is adopted since the indoor air temperature is increased by up to 3 °C in winter and decreased by up to 5 °C in summer. In addition, annual cooling and heating requirements can be reduced by 25% and 18%, respectively, by insulating the roof and walls with date palm fiber materials. On the other hand, it allows financial savings and a reduction in CO 2 emissions.
