“0” being the least amount of heat being allowed through a window
“1” being the most amount of heat being allowed through a window

Solar heat gain can warm a room during the day in the winter (providing free heating), but it can also cause overheating in the summer. Keep in mind, there is no solar gain at night.
Window & glass manufacturers are able to control the intended solar gain or decreased loss through various levels of tinting or coatings that can be applied to the glass.

High solar gain windows can be controlled in the summer with the use of external or internal shading devices.
