The uneven bark of the tree is designed to regulate the temperature of the tree as well as protect it from abiotic factors such as harsh winds or extreme sunlight. With reference to the physical appearance of the tree trunk applied to a building surface, we alternated the bark with solar panels which absorbed light to store energy as well as create shade(beneath the solar panels) throughout the hot seasons. Lastly, it is important to note that the panels are transparent(for windows) and at the same time deflect light rays in order to minimise heating.
