Holistic Quality Model for Extension of Existing Buildings: Social, Environmental, Technical and Economic Integration

IntCDC, RP 18-2

as part of the Cluster of Excellence “Integrative Computational Design and Construction for Architecture“ (IntCDC)

Funding: German Research Association (DFG)

Duration: 2022 to 2025

In the first project phase, the research partners developed the Holistic Quality Model (HQM) for supporting decision-making regarding the technical, environment and social quality of buildings and building processes already during the design and construction phase along control and decision points (Frost et al., 2022; Zhang et al., 2020). In the second project phase, economic quality will be added to the model to truly reflect all dimensions of sustainability. In addition, for its second iteration, we will extend and adapt the HQM to the use case of building within the existing building stock – whether this means extending, converting, or demolishing an existing building and building anew. While such infill development is important to the overall goal of compact and livable cities, it also presents potential sustainability trade-offs that require informed decision-making. The HQM 2.0 aims to support planning and construction stakeholders in this regard, thereby maximizing sustainability outcomes throughout the life cycle of buildings. An Expert Delphi will be used to gather insights on how experts in the field currently manage these types of tradeoffs. Based on these findings, the interrelations between the quality dimensions of HQM will be refined to better reflect the challenges faced by professionals today.

The research is conducted by the following institutes of the University of Stuttgart: Institute of Construction Management (IBL) (PI: Prof. Dr.-Ing. Hans Christian Jünger), Institute for Acoustics and Building Physics (IABP) (PI: Prof. Dr.-Ing. Philip Leistner); Institute of Engineering Geodesy (IIGS) (PI: Prof. Dr.-Ing. Volker Schwieger); and Institute for Social Sciences (SOWI) (PI: Prof. Dr. Cordula Kropp).
