The reuse of shipping containers in architecture has grown in popularity worldwide. However, few studies focus on understanding its thermodynamic behavior. The present study addresses, through numerical simulations, the transitory behavior of a typical house built with containers under different climates, both cold and warm. From completely naked containers, they are coated with materials of different insulation and thermal inertia, and observing their effect. Additionally, the orientation and other design resources such as height with respect to the ground, shadow elements and the position of the windows are taken into account. With all these multi-parametric studies, quantitative conclusions are obtained that can be taken into account in the design.
