- Energy & Cost Savings
Solar Heat Gain in Southern California climates climates that mainly require cooling (such as Palm Springs, Riverside and San Bernardino Counties, Los Angeles, Inland Empire, and parts of Orange County and San Diego County), windows have represented a major source of unwanted heat gain. In recent years, low-E coatings that reject solar heat without darkening the glass have undergone a technological revolution.
It is now possible to significantly reduce solar heat gain and improve comfort while providing clear views and daylight. The savings in cooling season costs associated with improved windows for a house in a cooling-dominated climate can save you anywhere from 7% to 35%. That means if your cooling bill is $150 a month, energy saving windows can reduce your bill from $150 to $630 annually-just in cooling costs. Depending on the condition of the old windows in an existing home, the savings can be higher, if window replacement leads to long-term air leakage reduction.
Heating Season Savings
In Southern California climates with a significant heating season (such as San Diego North County Coastal, Los Angeles County Coastal regions, Big Bear and other higher altitude areas), windows have represented a major source of unwanted heat loss, discomfort, and condensation problems.
Home windows have undergone a technological revolution to have lower heat loss, less air leakage, and warmer window surfaces-all to improve comfort and minimize condensation. The savings in typical heating season costs associated with improved windows for a house in the winter climates can save you anywhere from 11% to 28%. That means if your heating bill is $200 a month during winter season, energy saving windows can reduce your bill from $110 to $280 from November to March (typical winter season)-just in furnace costs. As with air elak loss in the summer, the savings can be even higher compared to old windows in an existing home, if window replacement leads to long-term air leakage reduction.
- Improved Comfort
Solar Heat Loss: An older window with a lower glass temperature feels colder because more heat is radiated from a person's body to the window. Cold glass can also create uncomfortable drafts as air next to the window is cooled and drops to the floor. This sets up an air movement pattern that feels drafty and accelerates heat loss. High performance windows with lower U-factors will result in a higher interior window temperature in winter and thus greater comfort. Proper installation along with weatherstripping designed to seal tightly (for operable windows) will also improve comfort by reducing the cold air leakage.
- Less Condensation
High-performance windows create warmer interior glass surfaces, reducing frost and condensation. High-performance windows with warm edge technology and insulating frames have such a warm interior surface that condensation on any interior surfaces is significantly reduced under all conditions.
- Increased Light & View-without the added cost of Window Tinting
- Reduced Fading-without the added cost of Window Tinting
Coatings on newly designed window glass can reduce the UV transmitted by up to 75 percent. UV absorbers can be incorporated into thin plastic films in multilayer windows, or as an interlayer in laminated glass. In both cases, the UV transmission can be reduced to less than 1 percent. Using Low-E coated glass, or windows incorporating plastic layers rather than clear uncoated glass, will reduce fading for many modern interior furnishings.
- Lower HVAC Costs
High-performance windows reduce the peak heating and cooling loads as well. The peak load for a building is the maximum requirement for heating or cooling at one time. These loads determine the size of the furnace, heat pump, air conditioner, and fans that must be installed.
Reducing peak load may allow homeowners to install a smaller heating or cooling system. Smaller HVAC systems cost less and as such can offset some of the cost of the efficient windows.
In warmer Southern California climate regions, using low-solar-gain low-E windows may allow cooling equipment to be two tons smaller than with single-pane windows and at least one ton smaller than with clear double-pane windows. Even in the cooler climates of Los Angeles, Orange and San Diego Counties, window choices can impact cooling equipment size by up to a ton.
