Commencing with a foundational understanding of the vital role energy modeling plays in optimizing building performance, this study meticulously compares a lowenergy lightweight concrete wall with a wooden stud wall featuring an air gap. The objective is to determine the most advantageous wall type for the construction phase, considering factors such as energy efficiency and cost-effectiveness. Additionally, comprehensive calculations will be performed to assess the heat resistance of each wall type and ascertain the most cost-effective option in terms of heating expenses for residential purposes.Acquiring pertinent information to successfully complete this study, our analysis considers variations in calculations based on whether the lightweight concrete wall is homogeneous or if the wooden stud wall consists of diverse materials.The findings of this study underscore that low-energy lightweight concrete walls offer notable advantages in terms of production aspects, primarily due to cost savings during the construction process. Moreover, in direct comparison to conventional lightweight concrete blocks, the study demonstrates that low-energy blocks outperform wooden stud walls in terms of energy efficiency and consumption.
