Technique for measurement of metabolism under work, from Francis Benedict Human Vitality and Efficiency, 1919 in Fluxtopia: On Life in the Metabolic City

We will begin by understanding the metabolic systems of the city, the key qualities of these systems and the agents responsible for their deployment. Through metabolism—or the processes that occur within an organism in order to sustain it—we can read the material and energy flows within a city. The metabolic model provides a framework to engage the natural and human systems intertwined in the urban environment. By understanding how people, materials and energy move into and out of the city, in multiple time cycles, it is possible to read the city dynamically through its various constituencies.
