Vacuum-Insulated Windows

by
If you look closely at a low viewing angle, you can see the tiny pillars in this prototype Guardian VIG panel.

Last week we took at look at one way to achieve very-high-performance windows: adding additional layers of glazing and multiple low-emissivity (low-e) coatings. This week, we'll look at another option that's even higher-tech: vacuum-insulated glass.

Making the Case for Triple-Glazed Windows

by
Reglazing the Rocky Mountain Institute in 2007 with R-20 center-of-glass Alpen Windows (now Serious Windows).

Just Say No to Idling

by
Idling a medium-sized car just five minutes each day will crank out about 30 pounds of harmful pollutants in a year plus 300 pounds of carbon dioxide.
