Matrix of Multifunctional Systems

Multifunctional facade and component systems integrate multiple building and construction-related functions into a single element or system. This functional integration enables optimized resource utilization, reduced spatial requirements, and streamlined construction processes. Typical examples include multifunctional ceiling systems that combine load-bearing capacity with heating, cooling, and technical building services, as well as facade systems that simultaneously provide structural support, solar energy generation, and ventilation (Deng, 2022, pp. 99–115; Penaranda Moren & Korjenic, 2017, p. 1).
Although numerous such systems currently exist or have existed in the past, there remains a lack of systematic analysis addressing the underlying physical processes, technical solutions, potential combinations of building and construction components, and resulting application scenarios. Consequently, there is also an absence of qualitative market analyses and structured identification of development potentials (Eßer & Keil, 2022, p. 1). The present application-oriented basic research project seeks to close this gap by specifying research needs for a subsequent COMET project.
The methodological approach builds upon the creativity technique of the Morphological Box, which facilitates criteria-based idea generation. This technique is operationalized through the systematic development of linked matrices representing relationships among technical, functional, and application-oriented aspects of multifunctional systems. Sequential analysis and combination of these matrices enable the identification of development potentials and their evaluation in terms of usability and market relevance (Kaufmann, 2021, pp. 163–175).
The project aims to deliver the following outcomes:

A precise definition of the relevant functional domains of multifunctional systems.
A systematic classification of applicable technologies and materials.
Identification of promising system configurations with high innovation potential.
A detailed description of research gaps, forming the basis for defining research objectives and work packages within a subsequent COMET project at the Alpine Building Center.

These results will contribute to advancing the development and application of multifunctional façade and component systems for both new construction and renovation projects, thereby maximizing their contribution to sustainable building practices.
