The construction sector is under increasing pressure to reduce its environmental impact while maintaining structural performance. Replacing massive and environmentally burdensome steel-reinforced concrete elements with thin-walled, geometrically complex components, guided by new design strategies, paves the way toward more environmentally sustainable construction. This study opens up the possibility of a dynamic evaluation strategy for the potential environmental impact of a modular ceiling element based on variable geometric design parameters.
The objective of this study is to evaluate the environmental performance of an innovative modular ceiling system based on a waterbomb origami design made of carbon reinforced concrete (CRC). The potential of design innovation and material substitution is assessed to collectively mitigate potential environmental impacts without compromising structural performance. A parametrized cradle-to-gate Life Cycle Assessment (LCA), in accordance with ISO 14040/44, is conducted to quantify potential environmental impacts. By implementing a parametrized approach, a large range of module configurations based on variable geometric design parameters can be modelled and evaluated.
The findings suggest that the implementation of CRC waterbomb modules provides the opportunity to significantly mitigate concrete demand while ensuring structural integrity. The parametrized approach is a promising solution that can be used to highlight trade-offs between design choices, structural reliability, and environmental performance. This can open the opportunity for future optimization of modular construction configurations. In conclusion, the study demonstrates the potential of coupling advanced structural design approaches with material-efficient CRC technologies to drive environmentally sustainable construction. The work contributes to the redefining of criteria for sustainable building components and supports the transition towards more resource-efficient construction practices by systematically integrating structural and environmental performance into design decision-making.
