Self Sufficiency

Hydroceramic is a project that speculate on the thermodynamic processes in buildings and how these can be tackled passively with a class of materials called “hydrogel”. By combining the evaporation property of the hydrogels with the thermal mass, and humidity control property of clay ceramic and fabric,  a composite material responsive to heat and water was created. The proposed solution is a passive evapotranspiration system able to lower the temperature of an interior space by 5ºC.



The project are divided into 3 phases, The smart material : Hydrogel, The supportive material : Fabric as water channel, and the ceramic.

From this evaporation diagram, We can see that the heat of vaporization of water is about 0.6 kilocalories per gram, that is how the a cooling effect occurs. Taking this phenomenon as a hypothesis, we set up a test to observe the cooling performance of this smart material in composition with other selected materials i.e. Plastic, Aluminum, Clay in order to find the most suitable supportive material.

The performative box compared to the control, after treated with extreme heat (artificial), resulted in 5 degree Celsius difference in temperature (average) and 200% higher in humidity. This gave us a rough conclusion that the composite material has the ability to cool down the enclosed space in high temperature and the ability to transfer humidity.

The project objectives has been answered in the research area. And as far as necessary, with limited time and technology, we have achieved a promising test result which could lead to several further researches and profitable projects. Having in mind that the composite material has very low cost production and the clay natural resources are still abundant, the system can easily be applied to architecture in remote area. With the help of accurate energy and thermal analysis of todays’ technology, hydroceramic’s passive system can effectively keeps the balance of the humidity and temperature inside the human comfort-zone.
