Drawing inspiration from the veinous ears of jackrabbits and elephants, Drexel University researchers have come up with a new ...

The Passive House certification process typically unfolds in two phases, the first being instruction on building science, which includes study of thermal environment, air quality, high-performance ...

In the U.S., it's still easier for developers to pass on the cost of cooling homes to residents rather than invest in passive ...

A huge chunk of energy usage goes towards heating and cooling homes and buildings, so it’s important to find new ways to regulate temperature passively. A new wood-based foam could drastically ...

Passive radiative cooling utilizes that thermal energy can leave an object in the form of infrared radiation. All objects emit heat as infrared light -- trees, buildings, water and even humans.

Peak Energy debuts the US's first grid-scale sodium-ion battery, cutting costs and boosting reliability with passive cooling ...

In contrast, passive radiative cooling technologies, which use outer space as a near-limitless natural heat sink, have been extensively examined as a means of energy-efficient cooling for buildings.

A tailored indoor setup for reproducible passive daytime cooling characterization. Cell Reports Physical Science, 2022; 100986 DOI: 10.1016/j.xcrp.2022.100986 ...

The new radiative cooling system incorporates a number of optically interesting design features. One of the central components is the polymer/metal film, which is made from a sheet of aluminum coated ...
