|Title||Predicting Evaporative Cooling Performance of Wetted Decorative Porous Ceramic Systems in Early Design Stages|
|Authors||Chilton, M., Gillott, M. and Vallejo, J.|
Passive evaporative cooling methods using porous ceramics were widely applied in the Islamic culture to reduce ambient air and surface temperatures and thus improve thermal comfort conditions under hot-dry environments. However, the integration and performance prediction of evaporative Porous Ceramic Cooling (PCC) systems in contemporary architecture is still complex due to the large number of environmental and physical parameters involved.
This paper explores alternative and more efficient applications of PCC systems: maximising cooling capacity, minimising water consumption and promoting the artistic expression of ceramics in architecture.
Laboratory testing and fieldwork were conducted using an optimised prototype and monitored data provided with relevant information regarding cooling performance. The obtained data was used to calibrate a Computational Fluid Dynamic (CFD) model which was used to explore the performance of different ceramic designs exposed to a wide range of environmental conditions.
The results were post-processed to develop a multi-steady state calculation tool to advise professionals on the design and performance prediction of PCC systems at early design stages. The system proved to be a good alternative to minimise local thermal discomfort, reducing ambient air temperature by 2°C and mean radiant temperature by 1.8°C on the leeward of certain PCC systems.
