One of the first and most interesting discoveries was the relationship between the absorbed surface radiation and the downward atmospheric emittance. (scienceofdoom.com)
- Low - e windows (the «e» stands for emittance or emissivity) feature a metallic oxide coating that doesn't let heat or UV - rays pass through, which will keep warm air in during the winter and prevent heat from the blazing summer sun from turning your home into a sauna in the summer.

Ronggui Yang, a professor and S.P. Chip and Lori Johnson Faculty Fellow in the Department of Mechanical Engineering at the University of Colorado at Boulder, who was not involved in the study, noted that significant challenges exist in obtaining wide - angle high solar absorptance materials with low thermal emittance.
