as limited ductility. Mechanical properties: NIAC tends to equalize the mechanical properties, especially ductility, in contrast to both natural and passive cooling. They concluded NIAC is viable and comparable to conventional cooling methods such as passive and natural cooling. Comparison with passive cooling Active cooling is usually compared alongside passive cooling in various situations to determine which provides a better and more efficient way of cooling. Both of these are viable in many situations but depending on several factors, one could be more advantageous than the other. Advantages Active cooling systems are usually better in terms of decreasing temperature than passive cooling systems. Passive cooling doesn't utilize much energy for its operation but instead takes advantage of natural cooling, which takes longer to cool over a long period of time. Most people prefer the use of active cooling systems in hot or tropical climates than passive cooling because of its effectiveness in lowering temperature in a short time interval. In technologies, it helps maintain proper thermal conditions, preventing the risk of damages or overheating of the core operation systems. It is able to better balance out the heat generation from the technology, maintaining it in a consistent manner. Some active cooling systems also contain the possibility of being self-sustainable as shown in the application of the thermoelectric generator compared to passive cooling where it is highly dependent on natural means to operate. Disadvantages The issues with active cooling compared to passive cooling are mainly the financial costs and energy consumption. Because of active cooling's high energy requirement, it makes it much less energy efficient as well as less cost efficient. In a residential setting, active cooling usually consumes a large amount of energy in order to provide enough cooling throughout the entire building which increases the financial costs. Engineers of the building would need to take in account that an increase in energy consumption would also play a factor in negatively affecting the global climate. Compared to active cooling, passive cooling are more seen being used in places with average or low temperatures.
