“…The design phase is the preliminary stage of the process, and the final results greatly depend on that. Therefore, it is necessary to supply technicians and designers with smart tools to accelerate the design procedure and to guarantee high performance standards [47][48][49]. In this study, a novel method was developed to support designers in the building process of modular temporary housing.…”

Building information modeling (BIM) is a process for managing the construction information model. The possibility of managing very complex construction orders using information processes has made the work of designers both easier and more productive. In this research, a new process of “assisted design” was implemented for self-assembling temporary houses with high environmental sustainability. The developed procedure allows for the supporting of a nonexpert user in the configuration of housing modules, using the base elements, and assisting them until the energy verification process based on the place of installation. Furthermore, a lifecycle assessment of emissions is made available. This is the result of the interoperability of software enabled by using BIM logic. The proposed work contributes to enriching the range of technical solutions developed to meet the demand for temporary buildings, providing a valid support tool in the design phase, especially when it needs to be completed within a short timeframe. This study introduces a smart configuration procedure that combines aspects of project automation and flexibility with energy efficiency and environmental sustainability needs required for the green transition of building stock.

The moving morphable components (MMC) method has been widely used for topology optimization due to its ability to provide an explicit description of topology. However, the MMC method may encounter the instability issue during iteration. Specifically, the iteration history is highly sensitive to parameters of the optimizer, that is, the move limits in the method of moving asymptotes (MMA). Additionally, the final topology obtained from the MMC method usually depends on the initial values. To address these issues and improve the stability of the MMC method in practical applications, this article introduces two strategies. The first strategy is based on the time‐series MMC (TSMMC) method, which proposes a unified description of curved components. However, the use of control‐points‐based design variables may introduce instability into the iteration process due to the strong locality associated with these variables. To mitigate this, global design variables have been incorporated into the formulation. Numerical examples demonstrate that this mixed formulation, combining global and local design variables, can enhance stability significantly. To further enhance stability, the second strategy involves using the trust region‐based moving asymptotes (TRMA) method as the optimizer instead of MMA. The TRMA method incorporates an accuracy control mechanism, resulting in stable and fast convergence behavior, as demonstrated in the numerical examples.
