IR imagery of heat loss through windows (IMAGE) DOE/Pacific Northwest National Laboratory Caption Infrared (IR) imaging technology (shown here) is one of the tools used to measure heat loss through poorly insulated windows. A series of research studies shows that a new generation of triple-pane windows can help improve energy efficiency in homes.
