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 Complex Less complex Least complex complex Development Most time More time Medium time Less time Least time time A week 5 days 3 days A day 2 hours Materials Most amount Medium Decent Less amount Least amount of materials amount of amount of of materials of materials 100 pieces materials materials 25 pieces 17 pieces 50 pieces 30 pieces Longevity Lasts for the Lasts for less Lasts for a Lasts for Last for the less amount amount of medium more amount most amount of time- a time – a year amount of of time- 10 of time- 20 month time- 5 years years years Buoyant Least Semi Effective More Very effective Effectiveness effective effective 100 Ibs. effective 250 Ibs. 50 Ibs. 100 Ibs. 150 Ibs.
