The Eco-network focuses on the multi-agents system. In the system we have different sub-systems:1.Network system 2. climatic system and more. We want to use parametric software to simulate people's behavior. We use people's angle of view, positive points in the garden and the negative points in the garden as our variable for calculation the people's paths. Then we will define the different characters of entrances and people's identities to control the paths. Lastly we will use this algorithm to build our whole networks in this garden. The network would be our mapping notebook to guide our cafe pavilion design. Because of the property of our cafe, this pavilion will give a feedback to our networks. As a result , our network is dynamic system .What we want to do is finding a balance in this dynamic network . At same time, the climatic system will affect our network system by solar variable and light variable. Then the network system would give a feedback to adjust itself for the requirements of entertainment.
