These two green shipping container condos were organized as small living areas that seem similar at a first glance, but are differentiated by a major factor: energy consumption. One of the condos is wasteful, while the other is an example of energy efficiency. The two improvised cribs each feature a glass wall, facilitating passers-by to take a look inside and watch the two actors “living” in their unusual homes. This display demonstrates that the smallest changes make a difference if they are practiced by everyone. It is sure nice to see effective advertising campaigns promoting positive behaviors.
