This paper attempts to approach and explore dynamic shells. A dynamic shell is defined as a building structure  that can use its artificial intelligence, manufacturing and materials to adapt to external environmental conditions with the ultimate goal of comfort of users  and the maximum energy saving of the building itself.

Through a historical overview of responsive architecture, intelligent buildings to the wall of Mike Davies and through “the mur neutralisant” of Le Corbusier to the double skin façade, we investigate the chronological evolution of the architectural innovations of the century that led to what we now call dynamic-responsive shell.

Then the study focuses on the close connection between architecture and ecology. This is achieved through a series of similes with the human nervous system and other adaptive mechanisms found in nature, through the use of biological structures and functions that can inspire the design of dynamic shells  and through the ecological interest to be found in high architecture through the movement of Eco-Tech.

A reference is also made to the quality requirements of the indoor environment that should be provided by a dynamic shell, with an emphasis on visual comfort, and the reinforcement of the building ensured by the contribution of passive systems.

The object of this research is quite new so the literature found is limited. The conclusions seek to provide an answer to whether the dynamic shells today have accomplished and to what extent  to reach their goal as well as if they can be used effectively in the future.
