Innovative construction in Canada’s extreme environments: Combining computational design and digital fabrication with modern timber techniques

Abstract

To help solve the housing crisis in Northern Canada’s permafrost zones, this article-based thesis explores the combination of Computational Design (CD) and modern construction techniques. The study discusses how Cross-Laminated Timber (CLT) and 3D printing can be used to develop adaptable, sustainable, and culturally suitable housing solutions that address the logistical, cultural, and environmental challenges of extreme climates. The research highlights the use of CD for the optimization of structural configurations and resources in remote construction sites, where transportation costs are expensive, and access is often challenging or even impossible. The research is organized around two main themes: the need to incorporate Indigenous culture values into architectural design and the technological potential of employing CLT and 3D printing in extreme environment. The case studies from Canada and international projects are used as references to evaluate how these construction technologies are applied in real-world contexts. Findings suggest that 3D printing presents a great opportunity in terms of waste reduction, customization, standardization, and ease of assembly. On the other hand, CLT offers a great alternative for conventional building materials, accelerating construction and reducing the carbon footprint. An important aspect of this research involved a participation in a two-week analog mission at LunAres Research Station in Poland. The mission simulated an isolated environment and brought relevant information of psychological challenges that a human can face in daily life during space missions. The mission underlined the need to design spaces that support psychological well-being, reduce stress, and offer privacy and human interaction. The mission presents essential results on resource management, health monitoring, waste reduction, and self-sustained habitat. Finally, the research reveals the need of continued innovation and collaboration between, industry, researchers, and indigenous communities to effectively address the distinct housing crisis of Northern Canada and promote environmental sustainability and respect of cultural heritage.
