The lighting configurations of buildings can be similar to how biological systems react to its environment. For example, many biological systems rest and conserve energy during night time, while lights would be turned off automatically during inactive periods in a smart lighting system. These adapatations also save energy. On the other hand, lights would still be turned on or adjusted in response to any stimulus (such as voice and movement). This is analagous to how biological systems wake up and react to environment stimulus even during sleep.
Pathways in buildings can also be analagous to the circulatory system of human body. The circulatory system moves blood and nutrients throughout the human body. Similarly in buildings, entrances and exits allow people to go in and out, and hallways, stairs, and elevators allow and facilitate the movement across the buildings. Their design determines how well the different areas of the buildings can be reached. Systems like power and water systems in buildings can also be part of this analogy, as they also need to deliver the necessary resources to different parts of buildings efficiently.
