Superwindow

Superwindow

A window with a very low U-value achieved through the use of multiple glazings, low-E (low-emissivity) coatings, and inert gas fills, usually argon or krypton, placed between sealed panes of glazing in order to provide resistance to heat flow.

It will also typically achieve multiple benefits from single expenditures -- a superwindow gets 10 kinds of benefits; a premium motor or dimming ballast gives about 18 each.
Energy examples include such things as hypercars, passive solar buildings, superwindow retrofits, super-refrigerators, low-energy beef, and redesigned fans, pumps and motors.
Similar coordinating benefits are achieved in many integrated engineering designs by using superwindows, daylighting devices, and alternative HVAC designs that regulate the temperature of the people as opposed to the spaces.
Hunter Lovins's two-part article ["Mobilizing Energy Solutions," January 28 (mistakenly titled "Supply-Side Stupor"), and "Energy Forever," February 11], the solution is simple, apolitical, and painless: "Policy tweaking" and innovations such as superwindows and Hypercars[TM] can turn gas-guzzling America into a cost- and energy-efficient nirvana.
In the superwindows, argon gas, which is inexpensive, nontoxic, clear and odorless, fills up the cavity to increase thermal performance.
Refuge oil could be displaced by making 4 percent of the light-vehicle fleet as efficient as the 48-mpg Prius hybrid-electric sedan, by making a fraction of car and light-truck replacement tires as efficient as the originals, or by putting superwindows into a fraction of U.
The larger the window, the more effective superwindows are in providing a comfortable temperature.
