Flexible form rammed earth, also known as earthbag construction or super adobe, is another earthen building tehnology that can be robust for the right use. The client commissioned this building as research into building technologies that would be appropriate for creating an optimal thermal envelope for a controlled environment agriculture research project. Constructed with earth bags and volcanic rock. The thermal perofrmance metrics exceeded the client’s expectations. Another example of how low tech materials can be used to create high performance buildings.
