Computational design and robotic fabrication for high environmental quality timber constructions: the livMatS Biomimetic Shell case study

The dataset includes the raw data and the corresponding report for the life cycle assessment of the building demonstrator 'livMatS Biomimetic Shell' (Website). The pressure on the construction industry to reduce its environmental impact is leading practitioners to investigate the use of more sustainable materials, such as timber. Still, due to its limited availability, it is questioned to which degree timber could substitute steel and concrete, and strategies to reduce its consumption are necessary. The Cluster of Excellence “IntCDC” investigates novel approaches to sustainable architecture. These exploit integrative computational design and automatic fabrication. These have been showcased in the livMatS Biomimetic Shell, for which a hollow timber cassette has been realized. In this study, the Lifecycle Assessment (LCA) analysis evaluated the developed cassette's environmental profile compared with other functionally equivalent systems. The analyses showed that the livMatS Biomimetic Shell reduced material consumption by 51% and a Global Warming Potential (GWP) 39% lower than conventional timber construction. Optimized fabrication processes allowed for emissions reduction by 60% in comparison with a solid cross-laminated timber box.

本数据集包含建筑示范项目'livMatS仿生外壳'（网站）的原始数据和相应的生命周期评估报告。面对建筑业降低环境影响的压力，从业者开始探索使用更可持续的材料，如木材。然而，鉴于木材的供应有限，人们对其能否替代钢材和混凝土的程度表示怀疑，并有必要制定减少其消耗的策略。卓越集群“IntCDC”致力于探索可持续建筑的新方法，这些方法利用整合计算设计和自动制造技术。这些技术已在livMatS仿生外壳中得到展示，其中实现了中空木材卡匣。在本研究中，生命周期评估（LCA）分析评估了所开发卡匣的环境特征，并与其他功能等效系统进行了比较。分析结果显示，livMatS仿生外壳将材料消耗降低了51%，其全球变暖潜力（GWP）比传统木结构低39%。优化的制造工艺与实心交叉层压木材箱相比，实现了60%的排放减少。
