Understanding EnergyStar Window Ratings and Savings

Something everyone has in common these days is the desire to save money. Homeowners can do this by upgrading their old, single-pane windows to EnergyStar-rated double- or triple-pane windows.

Savings
Modern windows can save over $450 in energy spending per year. This is especially true for areas which suffer from extremes in temperature. In places with hot, balmy summers and frigid, dry winters, homeowners have been known to save up to $665 on their energy costs.

Many high-performance options prevent water damage and mold by working to repel moisture, preventing it from entering the home. Savings are also possible in preserving the color of carpeting and fabrics, thanks to many of the different UV reflective coatings available.

How Ratings Work
The two primary ratings used to measure the efficiency of the window are the R-value and the U-value.

The R-value is what measures the level of insulation the glass and frame provides. The higher the value, the better insulated it is. The U-value is what’s used to rate how much solar energy is let in. The lower the U-value, the less solar energy is let in.

Windows with low-e coatings also have their own rating method. This is based on how much outdoor heat enters the home. Generally, they can repel up to 70% of the heat from outside. This gives your air conditioning a little less work to do in the summer.

Many windows have all three of these ratings to maximize efficient performance. The film, for example, can assist in further insulating the home, which in turn makes the unit more effective in lowering energy demand. When the warm weather rolls around, it can then reflect heat from the sun.

When you install new windows, you’re taking great strides to lowering your energy usage and therefore your monthly bills while adding more value to your home.
