The study proposes a low-tech, low-carbon formwork alternative for constructing fiberreinforced ice shell structures in Swedish Artic environments where leveraging local materials like ice and wood fibers can offer significant potential for innovation. A case study analysis of existing ice structures in cold climates identified formwork strategies, qualitatively assessing reusability, material sustainability, and logistical feasibility revealing a gap for low-cost and low-tech methods for building ice-composite buildings. Insights from this analysis informed the parametric design of a modular, reusable formwork, structurally evaluated using Finite Element Modeling (FEM). A wooden frame and fabric membrane were then fabricated and tested for casting fiber-reinforced ice blocks. The proposed method seeks to offer a scalable, affordable alternative for temporary shelter construction during crisis situations in remote cold regions.
