Parametric Optimization and Decision Support Model Framework for Life Cycle Cost Analysis and Life Cycle Assessment of Flexible Industrial Building Structures Integrating Production Planning

Abstract

Most industrial buildings have a very short lifespan due to frequently changing production processes. The load-bearing structure severely limits the flexibility of industrial buildings and is a major contributor to their costs, carbon footprint and waste. This paper presents a parametric optimization and decision support (POD) model framework that enables automated structural analysis and simultaneous calculation of life cycle cost (LCC), life cycle assessment (LCA), recycling potential and flexibility assessment. A method for integrating production planning into early structural design extends the framework to consider the impact of changing production processes on the footprint of building structures already at an early design stage. With the introduction of a novel grading system, design teams can quickly compare the performance of different building variants to improve decision making. The POD model framework is tested by means of a variant study on a pilot project from a food and hygiene production facility. The results demonstrate the effectiveness of the framework for identifying potential economic and environmental savings, specifying alternative building materials, and finding low-impact industrial structures and enclosure variants. When comparing the examined building variants, significant differences in the LCC (63%), global warming potential (62%) and flexibility (55%) of the structural designs were identified. In future research, a multi-objective optimization algorithm will be implemented to automate the design search and thus improve the decision-making process.

Evaluation of a Building Life Cycle Cost (Lcc) Criteria in Egypt Using the Analytic Hierarchy Process (Ahp)

“…Life cycle costing is an economic quantitative estimation method (ISO/TC59, B.C. Reisinger et al, 2022). This method evaluates the entire cost of a building over its operating life (Zhang et al, 2018;Noshadravanet al, 2017).…”

Evaluation of parametric multi-objective optimization and decision support tool for flexible industrial building design

“…In the context of this project, flexibility is defined as "the ability of the building structure to resist and adapt to changes in use through changing manufacturing conditions" (Reisinger, 2021a). The presets as well as the conditions the genetic algorithm respects when generating building structures around a previous optimized production layout, are briefly clarified within the next chapter (Reisinger et al, 2020, Reisinger et al, 2021bReisinger et al, 2022a;Reisinger et al, 2022b). The POD tool was tested in 2020 through a pre-study.…”

“…However, while parametric design and automated planning methods are increasingly finding their way into building design processes and individual areas of the planning disciplines are researched to be optimized, a holistic approach for integrated structural building design optimization is missing (Reisinger et al, 2021a). In our previous study we developed a tool to achieve integration and improve structural performance for flexible industrial buildings (Reisinger, 2021c;Reisinger, 2022b). Within this conducted study, we have implemented a MOO in the parametric design process, and the MOO tool is tried.…”

Study on an Integrated LCA-LCC Model for Assessment of Highway Engineering Technical Schemes

“…The current methods with the combination of LCC and LCA tend to lack certain integration and timeliness, and the results show some uncertainty in the input parameters [17]. Therefore, some scholars propose the basic idea of integration [18][19][20][21][22][23][24][25][26]. However, in specific practice, the application of life cycle integration assessment research is narrow.…”
