Nowadays it’s evidently more than ever that buildings are a lot more than only a design and construction process, but a system of relations occurring through them. Because of this, they have been started to be studied as a complex system, in order to try to understand the influences that occur between the different design, construction and management process. While the biggest amount of literature explores by a downstream point of view this topic to make analyses and studies about the structure of the complex system, this work tries to manage by an upstream approach the issue, by reversing the process and use common elements in building complex system as a design tool.
