Abstract text Arctic regions have a special interest in using urban underground space: one the one hand it offers excellent protection and energy efficiency in extreme weather conditions, one the other construction of underground structures and infrastructure represents significant investment and not always viable given towns size and population densities. Permafrost, including its alteration associated with climate change poses challenges to long term infrastructure resilience as well. Research on, planning, and using underground space resources accelerates globally. While combating extreme external climatic conditions has been long the main driving factor for using underground (e.g. Montreal underground pedestrian networks); nowadays underground space is more and more used to help creating sustainable cities, addressing density and infrastructure efficiency problems. Presented research is revisiting basic challenges and opportunities for urban underground space and infrastructure use, applied to the northern context. The paper will discuss strategic decisions on a sustainable spatial arrangement of a northern city taking into account underground space use aspects, and address a broader perspective of underground resources (water, energy, geomaterials, and space itself) use.
