Natural cooling the cheap and beautification way of cooling a shipping container home if you take a look at these photos below which are actually a medical housing centre called Salam Center located in Soba,Khartoum. Using natural materials to form partitions and a roof structure between container units you can get an idea from the photos below how much shade is being given. In the second photo you can see the partitions have created a walkway at the same time keeping the suns heat away from the container units but also allows airflow along the new partition corridor to aid in natural cooling.
Anderson Architecture + Nishiyama Architects, built this Japanese home although not made from shipping containers i thought it was an important find worth posting. The first thing is the use of natural materials that could brighten up any container home with things like solid or plywood ceilings with an added beam affect. The next was the layout of the structure as you can see it would fit in with using shipping containers very easily side by side or even better create a span across a few containers to allow maximum space with the least amount of material waste. The blend of natural woods, metal and white paint also give an airy feel to the property to give it a much wanted feeling of space.
