“…In addition, some studies tried to apply to the parametric design by the growth pattern of the L-system (Prusinkiewicz et al, 1988). Cai et al (2020) used the Paifangs' composition system, which transforms a graph and built-in components with L-system grammar derived from architectural rules. Therefore, deconstructing the system of components and applying computer logic to parametric design is a way to inherit the original system and carry out the generative design.…”

The work collected in these volumes has been produced during extraordinary circumstances, as the Covid-19 pandemic has continued to impact working and living conditions. Papers have been written, reviewed and edited throughout lockdowns, challenging family situations and health crises. The high number of submissions and quality of the papers is a testament to the resilience and strength of the CAADRIA community.The papers in this publication have been selected through a two-stage, doubleblind peer review process. All reviews and papers have been evaluated by the Paper Selection Committee. After receiving an initial 488 abstract submissions, a final set of 150 full papers has been selected for publication. We thank all authors for their contributions to the process and congratulate the accepted paper authors.The papers in these proceedings are specifically selected for their contribution to this year's conference theme, following the conference organisers' call for authors to position their work in relation to the United Nations Sustainable Development Goals (SDGs). As the world is experiencing the increasing impacts of climate change, there is an urgent need to reflect on the potential of the latest research in architecture, urbanism and construction to address these global challenges.Our special thanks go out to our more than 180 international reviewers, who volunteered their valuable time and effort. We also thank the organising team in Sydney for developing the 2022 CAADRIA Conference as a strong collaborative effort between academic institutions, industry and practice. We thank Gabriel Wurzer for his support during the proceedings' final production stage, and for facilitating their publication via the open access database CumInCAD.org. Finally, we sincerely thank the CAADRIA community for offering us the honour to serve as members of the paper selection committee for Post-Carbon, the 27 th International CAADRIA Conference 2022.

Realistic and delicate window models are in great demand for detailed LOD-3 urban reconstruction. However, current research tends to oversimplify the window models due to the difficulties in describing the complex window types and structure parameters. This work proposes a sketch-based window reconstruction method for procedural fac ¸ade modelling. With a rough sketch of the target windows, the method can quickly identify the window type and estimate the grammar parameters, eventually producing detailed 3D models with textures. The whole task is adopted within two neural networks: the classification network to judge the grammar category and the regression network to estimate the parameter value. The non-photorealistic rendering technology adopted in the present work can generate abundant training datasets, and meanwhile, the attention mechanism is used to identify the grammar parameters precisely. Experimental results on various data verify the effectiveness and accuracy of the proposed approach.

The large-span wooden construction project uses a sophisticated tenon joinery system to overcome the limitation on the size of the material. However, making a clear layout and knowledge transfer is an important issue under the complex structure. This research takes "Dougong" as an example to sort out the possible knowledge graph of Dougong. Through the geometric feature classification and the relationship between the joints, we found that the structural relationship of traditional Dougong is like the branch system of the L-system. But it has the characteristic of horizontal connections that make Dougong restrain one another more firmly. Besides a graphical representation of the complex joinery system, it can quickly visualize and adjust the type changes and therefore provide another network related to the building model. Besides computational geometry to traditional wood structure analysis and automation, we also explored two new types of Dougong from a perspective of the traditional wooden structure. So, in this research, we developed automatic digital tools for Dougong and propose new applications of Space Syntax, attempting to break through the existing limitations of Dougong.
