Simulation of a New Building, building resource passport, and life cycle assessment (LCA) Wangen
LIST Eco conducted an analysis of the demolition of an existing structure and its potential for the construction of a new LIDL store in Wangen.
As part of the analysis, a digital as-built survey was conducted in the form of a 3D point cloud, which served as the basis for creating the as-built BIM model. Various sources of information—such as as-built drawings, hazardous material reports, material analyses, and data from the demolition bid—were used to create a BIM-based building resource passport using Madaster. In addition, assessments of circularity and detachability were conducted using the Madaster Circularity Index and Detachability Index.
Subsequently, the results from the existing building were compared with the BIM-based new construction plans. To this end, LIST Eco identified, among other things, CO2 hotspots and material values in the existing building and derived measures and requirements for potential reuse. The goal was to evaluate different variants in terms of their material values and material-related CO2 emissions and to define at least five measures to promote climate protection and resource efficiency.
Simulation of the Existing Building and New Construction
As part of the remodeling process, both the existing building and a potential new construction were captured and evaluated as BIM models. The existing market in Wangen was captured using a point cloud and subsequently remodeled. Both the existing building model and the new construction model served as the basis for the further sustainability assessment and the final comparison of variants. The goal was to conduct a well-founded comparison of alternatives in terms of life cycle assessment (LCA) and circularity. In addition to greenhouse gas emissions and primary energy demand, the reusability and demountability of the materials and components used were also evaluated. This made it possible to identify which alternative offers the greater long-term potential in terms of sustainability. The findings from the variant analysis were incorporated into the evaluation and direction of the planning for future supermarkets.
