What better way to add style to your home while cutting energy costs at the same time, than adding energy efficient window treatments? Take a look at these options:
Look for drapes with lining and interlining—blackout lining protects from summer sun and heat, while thermally lined drapes (which have interlining made of thick flannel or other heavy material) shut out the cold. Homeowners in climates that don’t often dip below freezing can skip the interlining and save a bit of money, since the drapes and lining alone should insulate effectively.
Like shades and shutters, draperies are only efficient when they’re closed. However, if they’re used in conjunction with another window covering, such as a honeycomb shade or a wood blind, you can let sun in during daylight hours and effectively shut out colder air at night. When fully closed, the R-values of thermally lined drapes range from R-3 to R-5, depending on the type of fabric and the thickness of the lining and interlining.

When properly installed, window shades can be one of the simplest and most effective window treatments for saving energy.
Shades should be mounted as close to the glass as possible with the sides of the shade held close to the wall to establish a sealed air space. You should lower shades on sunlit windows in the summer. Shades on the south side of a house should be raised in the winter during the day, then lowered during the night.
For greater efficiency, use dual shades—highly reflective (white) on one side and heat absorbing (dark) on the other side—that can be reversed with the seasons. The reflective surface should always face the warmest side—outward during the cooling season and inward during the heating season, and they need to be drawn all day to be effective.

Both interior and exterior blinds help reduce solar heat gain while maintaining desired light, ventilation and privacy. When closed and lowered on a sunny window, reflective blinds (white or near white) are capable of reducing heat gain by 45 percent.
Ideal locations: South- and west-facing windows.
Best uses: Reducing heat gain where you still want options for light, ventilation and privacy.
Exterior blinds are potentially even more effective than interior blinds. Unlike interior blinds, they block heat before it is transmitted through the window and warms up the room. They are tricky to add to an existing window, however, so are best left for new construction. Source: Forbes
