Abstract
An emergency shelter for cold climates is disclosed. The shelter has a thermally insulating inner shell shaped to provide an occupant with adequate space for sitting, lying down or performing necessary tasks, while minimizing a technical volume and surface area for thermal efficiency. To this end, the shell has a small foot section, a taller knee section and a taller and wider head section joined to the knee section by an appropriate transition. The shell has an inflatable, impervious, self supporting outer layer and an air pervious, insulating inner layer. A canopy extends over the foot, knee and transition sections to provide a heat transfer diameter around those sections of the shell. The outer layer of the shell has an opening into the heat transfer chamber for ventilation.
