The consumption of energy for cooling is an important issue, especially in subtropical climates where there are high temperatures and dry weather the summer; this climate forces homeowners to use mechanical-electric ventilation. main advantage passive minimize demands which required achieve thermal comfort buildings, with exhibiting ambient temperatures. This paper presents a detailed literatur...

Passive radiative cooling materials that spontaneously cool below ambient temperature can save tremendous amounts of energy used for applications. A multitude materials, structures, and fabrication strategies have been reported in recent years. Important material parameters like a tailored or broadband emissivity, angle selectivity, the influence nonradiative heat losses were discussed detail. ...

Existing passive cooling solutions limit the short-term thermal output of systems, thereby either limiting instantaneous performance or requiring active cooling solutions. Active cooling requires relatively large amounts of power, and cannot easily and efficiently handle temperature spikes. PCMs (phase change materials) are materials that can change phase at a device’s operating temperature, ab...

A passive no electricity and sustainable cooling on-demand (NESCOD) system can convert store solar energy for cooling.
