This section indicates the life principles related to energy management form nature species. For example, the water is captured by the tree from cloud. In tropical forest the trees need deal with the dry season which lead insufficient water from the ground to satisfy the need of trees. Thus, leaves use their surface to absorb water from cloud or fog.

The function of water collection can inspire designer to generation for urban building design.

The sunlight is harvested form oriental hornet. Hornet tend to work in direct sunlight because the surface of them allow them to absorb sunlight by multiple layers. Besides, oval-shaped bumps can increase effectiveness for sunlight absorption on the outer yellow layer. The successive thinner pigments have ability to absorb the solar energy and transfer heat to other locations. Further and detailed biological solution is shown in the version level 3 BID card.
