Within the second design problem, designing a cost effective shelter, are five smaller problems. The first problem is the type of materials that are incorporated into the shelter’s design. To help create a cost effective shelter, local materials, that conserve energy, are used. This is achieved by using a material whose color, reflectivity, and thickness matches that of the regional’s environmental needs. In addition, light durable materials are used to create lightweight shelter packs to ease during the shelter’s transportation to the desired location by both vehicular and pedestrian methods.
The second problem is to analyze the various ways the shelter can arrive at the desired site or village. When doing this, four ways were analyzed (train, tractor trailer, cargo barge, and cargo airplane). Using an average 100 car train, 400 shelters can be transported. Using an average 53 foot long tractor trailer, 4 shelters can be transported. An average Boeing 747 can carry 250,000 pounds of cargo. With the 4,000 pound proposed shelter, a cargo plane could carry 62 shelters. An average cargo barge can carry 20,000 tones. With the 4,000 pound proposed shelter, plus the weight of a shipping container, a cargo barge could carry 2,020 shelters. Therefore, with the village’s close proximity to the Mississippi River, the most practical transportation method is a cargo barge.
Other graphics that need to be explained to help solve the first two problem statements are the shelter’s floor plan, elevations, and shelter model pictures. The floor plan shows the layout of the needed spaces, as well as a general layout of the furniture and appliances. The four elevations show the slopped roof for colleting rainwater, the various sizes and treatments of the windows, and how the adjustable legs raise the shelter to fit a changing grade.

After a natural disaster, the area’s water and power sources can be disconnected for weeks. To help solve this problem, solar gaining fabric, a solar battery (A), and a cistern system (B) is incorporated into the design. In addition, these elements, once the city’s sources are reconnected, can increase the shelter’s cost effectiveness by decreasing the inhabitants’ water and electric bills.

Due to these five cost effective techniques, the materials of the pre-designed temporary shelter, on an average, costs $14,260. However, the estimated does not take the manufacturing, transportation, and storage costs into consideration. Even if the shelters material cost by was multiplied by a factor of 1.5 ($21, 390), the proposed 448 square foot pre-designed shelter would still cost $34,350 less than that of that of an average 350 square foot FEMA trailer.
