Choosing the Right Replacement Windows for California

Choosing the Right Replacement Windows for California

Right now it makes sense for homeowners to consider energy efficient replacement windows in California. For one thing, you may qualify for a Federal tax credit of $1,500 and at the same time cut your annual heating and cooling costs. But there's even more to it. The Department of Energy reports that with new ENERGYSTAR rated windows you can also:

• Improve daylight and view through your windows
• Prevent winter cold drafts, strong summer sunlight
• Reduce fading of furnishings and internal moisture, mold or mildew

Finding Replacement Windows for Your Part of California

The National Fenestration Rating Council (NFRC) applies stickers to windows in the showroom or those shown by contractors to identify the energy performance of replacement windows. The ratings vary by the portion of the state in which you reside. In the north of the state, windows designed to improve home heating are common, while in the southern part of the state, windows should be optimized for home cooling.

Requirements for rebates and top window efficiency by minimum U-factors and Solar Heat Gain Coefficients (SHGC) are:

• Northern California: U-factor: d 0.30, SHGC: no requirement
• North Central California: U-factor: d 0.32, SHGC: d0.40
• South Central California: U-factor: d0.35, SHGC: d0.30
• Southern California: U-factor: d0.60, SHGC: d0.27

U-factors measure non-solar heat loss and gain. The lower numbers reflect a replacement window's insulating efficiency. SHGC measures heat gain from sunlight. The lower the number on the rating, the greater the window's ability to block harmful rays.

In California, window replacement contractors are required to hold a license. To determine if your window replacement specialist is licensed, contact the Contractors State License Board within the California Department of Consumer Affairs.
