Human Centered System

These are some little diagrams I've made, representing what a person needs in life and what they produce. I tried to focus on things that are currently considered 'waste', such as grey water, that could be re-used to provide something else they need. By creating a diagram I can see what needs will be fulfilled by the house itself.
These could be a great way to get some collaborative input from people, they're quick and easy to do. If you have a chance to draw one yourself, I would love to see it posted!
Doing a diagram exclusively of human 'output' was pretty revealing. I found it a lot harder to do, and the concrete items were much fewer. Most of the things on the 'output' chart were things that are generally considered "waste", but with some ingenuity they could actually be used to provide for more of our needs. The other problem was that although we consume lots of food, it's hard to quantify what we actually produce with it aside from living.
