Leaf Venation
To ensure that resources are evenly distributed to all part of the tree, and even all parts of leaves, nature has calculated an ultra-efficient model of distribution.
Biomimetic Designs
Architectural Development:
Structural components of buildings are all centered around even distribution of problems or resources. This problem of distribution can be found in anything from circulation and ventilation, to heating and cooling, and even how the weight is distributed within the structure. For example, New York based architect, Hart Marlow, is currently in the works of designing a building constructed primarily from the venation patterns shown in leaves.

Infrared Absorption Material:
Leaf venation is not only responsible for the distribution of nutrients and removal of waste, it is also responsible for the temperature regulation of the plant's extremities. Scientists are now looking to leaves to inspire the distribution of IR-absorbing or reflecting polymers to enhance materials. Such materials can be used to trap heat, such as the glass of a greenhouse, or block it, like the metal walls of a furnace.

The Science Behind Leaf Venation
Venation is the pattern of veins present in the blade of a leaf. The veins are made of vascular tissues that support and control everything from the distribution of nutrients and temperature, to the extraction of waste and products. Depending on the type of plant and the specific functions the leaves must account for, there are a variety of venation patterns. However, no matter the pattern, the main purpose of veins within the plant are to control the distribution of resources. This is done through a hierarchical system of veins, most clearly shown in the structure of a tree. From the tree trunk come branches, which diverge into smaller branches, from which leaves grow. Even within the leaves, there becomes a progressively higher order (one through four) of veins until they terminate at the end of the veining system.

Along with the architectural inspiration provided by the technical functions of the veins, "venation geometry and density influences mechanical stability". Both of these aspects can be interpreted by architects to then morph their buildings in an ecophysiological context.
