Passive cooling refers to technologies or design features that lower the temperature in spaces without the need for power consumption. The strategy uses free, renewable sources of energy (wind and sun ...

A new passive cooling system relies on evaporation and radiation and requires no electricity. The device can provide up to about 19 degrees Fahrenheit (9.3 degrees Celsius) of cooling from the ambient ...

With rising temperatures, humans have become more reliant on cooling technology to maintain stable temperatures. As a result, buildings are using more energy to cool, and urban areas are particularly ...

Researchers in Sweden sought to raise the efficiency of ground source heat pumps by combining their operation with that of PVT systems and free cooling. Through a series of simulations, they found ...

As the world gets warmer, the use of power-hungry air conditioning systems is projected to increase significantly, putting a strain on existing power grids and bypassing many locations with little or ...
