Scale: The greater, the better Complexity: 1 most complex, 5 least complex A more complex design will be inefficient to build, whereas a less complicated design is able to be build in must less time. Development Time: 1 most amount of time, 5 least time A design that needs more time to organize the details will not be worth the time put into it while a simple design will be easy to follow. Materials: 1 most amount of materials, 5 least amount of materials Being conservative, even in a recyclable project is very important. The less waste the better. As the number of materials and the quantity of materials becomes less, the efficiency of the design is increased, making the eco-project even more environmentally friendly. Longevity: 1 lasts for a short period of time, 5 lasts for a long period of time Even the lifespan is important for a product. If the product will not last for more than a few months than it isn’t worth the small cost put into it on top of the materials cost. The product lifespan is to be maximized. Buoyant Effectiveness: 1 not very effective, 5 very effective The goal of the eco-project: Floating Dwelling is to float a small residence, if the design is unable to float very much weight, then the design is not a good one. Cost: 1 not very cost effective, 5 very cost effective A net cost of the project, including outside materials, which is not ideal, shows how truly eco-friendly the project is. 1 2 3 4 5 Complexity Most complex More
