A biological system, such as the human body, has to overcompensate when there is a deficiency. For example, if an individual is cold then the body will limit the blood circulation to the least important parts of the body in order to keep the prioritized parts functioning properly. For example, fingers will become pale and extra cold as the body tried to keep the other parts warm. Similarly, unequipped buildings will have to overcompensate by adding additional heaters where humans are most present and use a lot of energy to achieve thermal comfort. Many times, this means having extra cold spaces.
