Table 1.
Fall 2018 average monthly electricity and domestic water consumption for the functional groups.
This does not include utility plants, whose needs are considered self-addressed.

Fig 2.
Diagram of the campus network model for electricity and domestic cold water, showing all thirteen actors.
The diagram for domestic hot water is the same with the exclusion of the event venues, sports, TV and radio stations, greenhouses, and museum.
Fig 3.
Digraph for the electricity and domestic cold-water networks.
The top digraph represents the original electricity and domestic cold-water network while the bottom digraph represents the modified network. The digraph for the domestic hot water network is the same, but with only nine nodes. Node 1 represents the utility plants. Node 14 represents the environment. Nodes 2–13 represent the other actors. Orange arrows represent the added links.
Fig 4.
Structural matrix for a hypothetical food web, used with permission from [51].
Flows are transferred from the row to the column. For example, energy is transferred from the rabbit (actor 1) to the bird (actor 2) so there is a one in row 1 and column 2.
Fig 5.
The ecological flow matrix [T], used with permission from [55].
Flows are transferred from row to column. The first row is system imports and the last two columns are system exports (useful and dissipation).
Table 2.
Modifications for electricity and domestic water represent the percentage of solar power and rainwater collection respectively. Food web values are taken from [46, 55].
