The thermal characteristics of today's insulating technologies closely resemble animal thermal adaptations. Since architecture and walruses are both faced with the same internal problem of thermal stability it seems only logical to look to animal adaptations to understand how these new innovations could be implemented into architectural design. With an emphasis on design expression of these thermal materials, this project is split between both investigation and exploration of thermal adaptations. The first, being an evolutionary investigation of animal and architecture thermal strategies. The second is the exploration of thermal expression in architectural design.
