What is the principle behind a passive cooling system?

A passive cooling system operates based on natural phenomena and does not rely on mechanical or electrical energy to achieve cooling effects. The main principle behind this system is the utilization of natural elements such as ventilation, thermal mass, and material properties to maintain comfortable temperatures within a building.

For instance, passive cooling methods may include the strategic placement of windows for cross-ventilation, the use of materials that absorb and release heat slowly, and shading techniques to protect spaces from direct sunlight. These approaches create a comfortable indoor environment without the need for energy-intensive equipment, making passive cooling an environmentally friendly and sustainable choice.

This method stands in contrast to systems that depend on mechanical components, such as fans and air conditioners, or electrical inputs to generate cooling. Additionally, while some advanced cooling strategies might involve chemical processes (like absorption cooling), passive systems fundamentally rely on non-mechanical, natural cooling methods.
