Insu-ram is a system of assembling blocks inspired by the cells in the wing covers of certain beetles that allow internal air flow to circulate. Insu-ram both cools and insulates a space from external heat without the use of machinery. The external pattern of the block generates a micro-shading effect that reduces the solar contact surface. Local biodegradable materials, such as rammed earth, clay, and manure can be used in making the blocks. The blocks can be produced locally and offer a way to build thermally comfortable houses in a fast, cheap, and efficient way. These cells of the beetle wings increase their density towards the outside, generating a rigid layer that insulates them from heat and decreases towards the inside, allowing the passage of fluids.

Reducing carbon emissions due to heating and cooling, as well as offering a way to build thermally comfortable houses for a lower cost.

This system is particularly sustainable because of the materials used, its low carbon footprint, and the lack of need to introduce electrical cooling mechanisms to make it work. Nature uses chemistry and materials that are safe for living beings, and all the materials utilized to fabricate these bricks are biodegradable and non toxic, ensuring that the footprint on the ecosystem is minimal.
