Holistic Quality Model for Extension of Existing Buildings

Research Project 18-2 (RP 18-2)

HOLISTIC QUALITY MODEL FOR EXTENSION OF EXISTING BUILDINGS: SOCIAL, ENVIRONMENTAL, TECHNICAL AND ECONOMIC INTEGRATION

In this project we will extend the Holistic Quality Model (HQM) developed in the previous Research Project RP 18-1 with its social, environmental and technical characteristics to include economic characteristics and their interrelations. Thus, all aspects of the sustainability triangle will be considered within the HQM. This makes it possible, for example, to link economic and environmental aspects by providing the same result in terms of environmental quality at lower cost or in less time.

IntCDC is developing several novel building systems (e.g. for fibre and biocomposites), which require interdisciplinary as well as disciplinary research on quality modelling and assessment when adopting the HQM.

Holistic quality assessment is a challenge not only for newly planned buildings, but also for the existing building stock. For the latter, we will consider and acquire the initial or boundary conditions and establish new quality criteria for the various quality parameters in order to inform and support decision making already at the earliest stage when the decision about extension/conversion vs. demolition and new construction in the urban context is at stake. The HQM and the corresponding quality assessment will provide a methodical contribution to support these co-decisions.

Coreless filament winding extends industrial processes, reduces formwork, and allows for tailoring of fiber layups to specific requirements. A previously developed computational co-design framework for coreless filament winding is extended toward the integration of reciprocal design feedback to maximize design flexibility and inform design decisions throughout the process. A multi-scalar design representation is introduced, representing fiber structures at different levels of detail to generate feedback between computational design, engineering, and fabrication. Design methods for global, component, and material systems are outlined and feedback generation is explained. Structural and fabrication feedback are classified, and their integration is described in detail. This paper demonstrates how reciprocal feedback allows for co-evolution of domains of expertise and extends the existing co-design framework toward design problems. The developed methods are shown in two case studies at a global and component scale.}}, author = {Kannenberg, Fabian and Zechmeister, Christoph and Gil Pérez, Marta and Guo, Yanan and Yang, Xiliu and Forster, David and Hügle, Sebastian and Mindermann, Pascal and Abdelaal, Moataz and Balangé, Laura and Schwieger, Volker and Weiskopf, Daniel and Gresser, Götz T and Middendorf, Peter and Bischoff, Manfred and Knippers, Jan and Menges, Achim}, doi = {10.1093/jcde/qwae048}, eprint = {https://academic.oup.com/jcde/article-pdf/11/3/374/58347694/qwae048.pdf}, issn = {2288-5048}, journal = {Journal of Computational Design and Engineering}, month = {05}, number = 3, pages = {374-394}, title = {{Toward reciprocal feedback between computational design, engineering, and fabrication to co-design coreless filament-wound structures}}, url = {https://doi.org/10.1093/jcde/qwae048}, volume = 11, year = 2024 }

During design iterations, vast amounts of data in different reference systems, origins, and significance are generated. This data is often not directly comparable or is not collected at all, which implies a great unused potential for advancements in the process. In this paper, a novel workflow to process and analyse the data sets in a unified reference frame is proposed. From this, differently sophisticated iteration loops can be derived. The developed methods are presented within a case study using coreless filament winding as an exemplary fabrication process within an architectural context. This additive manufacturing process, using fiber-reinforced plastics, exhibits great potential for efficient structures when its intrinsic parameter variations can be minimized. The presented method aims to make data sets comparable by identifying the steps each data set needs to undergo (acquisition, pre-processing, mapping, post-processing, analysis, and evaluation). These processes are imperative to provide the means to find domain interrelations, which in the future can provide quantitative results that will help to inform the design process, making it more reliable, and allowing for the reduction of safety factors.

An interdisciplinary approach is taken by combining the perspectives of social and engineering sciences to discuss the contribution of green façade systems for more-than-human conviviality in cities. Green infrastructures can support this endeavor by enabling functions that help to integrate the heterogeneity typical for semi-natural structures into urban ones, especially regarding microclimatic and biodiversity-enhancing functions. The theoretical distinction between “gray”, “green”, and “revolutionary” infrastructure is used to differentiate between conventional and posthumanist conceptualizations of urban naturecultures. The performance of the UNA TERRA living wall prototype as a green and revolutionary infrastructure is evaluated. The results show that the living wall has beneficial microclimatic effects and adds a heterogeneous habitat structure that supports biodiversity in the urban context. By adhering to “egalitarian humility” in design, the uncertainty and openness of more-than-human conviviality are acknowledged. The study finds that green infrastructures such as green façade systems can fulfill the criteria of revolutionary infrastructure if the contribution to local biodiversity and structural complexity is prioritized and the heterogeneous interrelations between human and non-human actors are taken into account.}, author = {Bornschlegl, Sebastian and Krause, Pia and Kropp, Cordula and Leistner, Philip}, doi = {https://doi.org/10.3390/ buildings13061393}, journal = {Buildings}, language = {engl}, month = {05}, number = 6, pages = 1393, title = {Analysis of the Microclimatic and Biodiversity-Enhancing Functions of a Living Wall Prototype for More-Than-Human Conviviality in Cities}, url = {https://www.mdpi.com/2075-5309/13/6/1393}, volume = 13, year = 2023 }

The final geometry of the produced part results from the interaction of fibres in space and is initially undetermined. Therefore, the success of large-scale coreless wound fibre composite structures for architectural applications relies on the reciprocal collaboration of simulation, fabrication, quality evaluation, and data integration domains. The correlation of data from those domains enables the optimization of the design towards ideal performance and material efficiency. This paper elaborates on a computational co-design framework to enable new modes of collaboration for coreless wound fibre–polymer composite structures. It introduces the use of a shared object model acting as a central data repository that facilitates interdisciplinary data exchange and the investigation of correlations between domains. The application of the developed computational co-design framework is demonstrated in a case study in which the data are successfully mapped, linked, and analysed across the different fields of expertise.

A graded concrete slab serves as an example to illustrate how to consider technical, environmental, and social quality criteria and their interrelations. The evaluation of the design and production process of the graded concrete component shows that it has advantages compared to a conventional solid slab, especially in terms of environmental performance. At the same time, the holistic quality model identifies potential improvements for the technology of graded concrete. It will be shown that the holistic quality model can be used to (a) consider the whole life cycle in decision-making in the early phases and, thus, make the complexity of construction processes manageable for quality and sustainability assessments and (b) make visible interdependencies between different quality and sustainability criteria, to help designers make better-informed decisions regarding the overall quality. The results show how different quality aspects can be assessed and trade-offs are also possible through the understanding of the relationships among characteristics. For this purpose, in addition to the quality assessment of graded concrete, an overview of the interrelations of different quality characteristics is provided.

  @article{yang2021monitoring, abstract = {Accepting the ecological necessity of a drastic reduction of resource consumption and greenhouse gas emissions in the building industry, the Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart is developing graded concrete components with integrated concrete hollow spheres. These components weigh a fraction of usual conventional components while exhibiting the same performance. Throughout the production process of a component, the positions of the hollow spheres and the level of the fresh concrete have to be monitored with high accuracy and in close to real-time, so that the quality and structural performance of the component can be guaranteed. In this contribution, effective solutions of multiple sphere detection and concrete surface modeling based on the technology of terrestrial laser scanning (TLS) during the casting process are proposed and realized by the Institute of Engineering Geodesy (IIGS). A complete monitoring concept is presented to acquire the point cloud data fast and with high-quality. The data processing method for multiple sphere segmentation based on the efficient combination of region growing and random sample consensus (RANSAC) exhibits great performance on computational efficiency and robustness. The feasibility and reliability of the proposed methods are verified and evaluated by an experiment monitoring the production of an exemplary graded concrete component.

This model should consider social, environmental as well as technical aspects and thus enable a holistic quality assessment of the building. For the technical part of the model quality parameters and characteristics for many different disciplines like architecture, structural engineering, engineering geodesy, mechanical engineering and system engineering should be included. This definition of the critical parameters will take place in close alignment with the co-design-based development of building systems. In addition, the construction processes are modelled in order to allow quality propagation through the construction process. This contribution will deal with a first quality concept, a first quality model as well as exemplary quality characteristics and parameters gathered from concrete and timber constructions.

  @article{horn2020bim2lca, abstract = {An increasing degree of digitalization in construction planning offers significant potential for building life cycle assessment (LCA) to reduce access barriers, as well as the assessment effort itself. To realize the widespread application of LCA tools and their potential to effectively minimize life cycle impacts, an open approach is required that allows for flexible application of comprehensive LCA studies and early integration in planning processes. The authors present an approach for LCA integration in all phases of digital planning which aims at a DGNB (Deutsche Gesellschaft für nachhaltiges Bauen) certification based on the open Building Information Modeling (BIM) standard Industry Foundation Classes (IFC). The approach takes into account varying levels of development and resulting data availability during integral planning phases, as well as resulting LCA application contexts. It goes beyond existing strategies and allows one to consider both BIM and LCA software through a workflow based on a single data format. The assessment framework is operationalized through standardized interface development and technical realization following the information delivery manual (IDM) process standardized for IFC interfaces. The Extensible Markup Language (XML) schema, as a specific implementation for certification, provides the target system for LCA data requirements and is generalized to a planning phase specific IDM base table. The technical realization based on respective model view definitions and distributed data suggests a pathway to the standardization of LCA-IFC integration based on an open approach. The overall approach exemplarily applies to the “LERNZENTRUM” at the Karlsruhe Institute of Technology (KIT) campus. We conclude that an open BIM approach for LCA integration in model-based planning is feasible, but requires several adjustments in IFC, LCA, and planning practice. Adding a lifecycle element to the IFC to connect BIM and LCA provides comprehensive feedback for informed decision making based on environmental impact.}, author = {Horn, Rafael and Ebertshäuser, Sebastian and Di Bari, Roberta and Jorgji, Olivia and Traunspurger, René and Both, Petra von}, doi = {10.3390/su12166558}, journal = {Sustainability }, language = {english}, month = {07}, number = 16, pages = 6558, title = {BIM2LCA Approach: An Industry Foundation Classes (IFC)-Based Interface to Integrate Life Cycle Assessment in Integral Planning}, url = {https://www.mdpi.com/2071-1050/12/16/6558}, volume = 12, year = 2020 }

In Albania the building sector accounts for 26, 9% of final energy consumption, offering high energy saving potentials due to the great number of old residential buildings. Intervention is not always possible and, in order to achieve significant environmental savings, the national action plans cannot rely only on the physical improvement of existing buildings. This paper proposes a probabilistic LCA and LCC evaluation model using MC simulation, for the prediction of intervention options in existing buildings. The potential environmental and economic impacts of three intervention options: standard, ambitious retrofitting and new construction during the whole life cycle of a building are analysed. A framework is defined, with the purpose of estimating the value of a building in a specific time during its life cycle. Comparing the generated values of potential environmental impacts and associating them with the changes on the buildings value enables the process of deciding upon the most desirable and/or agreed combination. The results of the SLED Study 2015 on Albanian building typology are used, while the new construction model is defined according to German EnEV2014 requirements. The GWP values from the LCA/LCC assessment of the intervention scenarios, done through the SBS tool of Fraunhofer IBP, are used to create a prediction model for future alternative solutions especially in early planning phase.

Lightweight and at the same time adaptive solutions for building shells and structures are a potential answer to the high and increasing use of resources in the construction industry. To live up to this expectations, adaptive solutions need to provide damagefree buildings with appropriate quality of living as well as significantly higher resource efficiency. Both criteria apply to the entire life cycle and need to include the additional operating energy required for adaptivity. In a previous study on adaptive lightweight constructions for facades, the physical functionality and environmental impact of some use cases were discussed at component level. In the present article, the horizon is extended to the room level. This extension enables the inclusion of characteristic values for thermal and moisture protection of the shell as well as the comfort in the room as evaluation indicators. This increases the required effort and complexity of the assessment, but the application potential of adaptive alternatives can be assessed more thoroughly and thus the information quality for decision-making on the further utilization is improved. In the study three conventional constructions, partly massive and partly lightweight constructions, as well as equivalent adaptive facades, are considered and assessed on room level. The essential evaluation criteria are quantitative statements on the fulfillment of building physics requirements and on environmental impacts. The results of the applied inter-methodological research indicate a great potential for reducing resources without restricting functionality by adaptive constructions.

The model may also be complemented by the static and energy performance of buildings. Facing the growing demand of sustainability strategies in the construction sector, the consideration of environmental information within the planning process influences the decision making of planners and stakeholders. Nevertheless, the life cycle assessment of buildings has been so far excluded in BIM, due to the high variety of accurate information and time required. In this paper, a systematic framework is presented and applied to a case study. BIM-LCA assists actors along the planning and designing phase, from the building conception as a whole, up to the elements' details and materials' definition. BIM and LCA intertwine in an application scheme of seven phases for integral planning and four levels of structural composition of a building. With respect to these, involved actors examine potential solutions through a tool which exploits alternative specifications in order to assess the environmental impacts. The goal of this paper is to demonstrate the application of a BIM-LCA model regarding decision making for reliable values of environmental impact in a given structural level of the building. The main findings of this framework are due to the multitude of actors and information orchestrated, namely to uncertainties which characterize the whole planning process and data handling.
