TLDR
In this paper, the authors investigate the radiative heat transfer between blackbody-like surfaces confining an infrared-absorbing gas layer, and find that the gas is able to diminish the heat flux across a 1 cm-thick slab by a factor -0.7 in comparison with the case of a nonabsorbing medium.Abstract:
We investigate the radiative heat transfer between blackbody-like surfaces confining an infrared-absorbing gas layer. Spectrophotometric measurements on selected gases lead us to optimized compositions with sulfur hexafluoride, propyne, and different freons. Theoretically, the gas is able to diminish the radiative heat flux across a 1 cm thick slab by a factor - 0.7 in comparison with the case of a non-absorbing medium. Infrared-absorbing gases seem to offer interesting possibilities for improved transparent thermal insulation of windows.read more

Double-layer nanoparticle-based coatings for efficient terrestrial radiative cooling
TL;DR: In this paper, a double-layer coating consisting of a top reflective layer with high solar albedo and a bottom emissive layer are achieved by properly designed TiO 2, SiO 2, and SiC nanoparticles.

Comparison between PCM filled glass windows and absorbing gas filled windows
TL;DR: In this article, a comparison between the thermal efficiency of two glass windows one filled with an absorbing gas and the other with a PCM and exposed to solar radiation in a hot climate is done.
The utilization of participating gases and long-wave thermal radiation in a passive cooling skylight
TL;DR: In this paper, Radiative cooling using the window concept is used to simulate thermal insulation and cooling and the effect of window material on thermal insulation is discussed. But the authors do not consider the effects of gas and window material.
