So talk about solar heat gain and energy star windows needed. As you might know, The U.S. Department of Energy estimated many things to me in previous posts and statements. However this post was recently updated. It use to say that the amount of energy lost annually through windows is $35 billion.

However, most interestingly, it is now not listed on the Energy Star website. So therefore I therefore State I believe it.

Yes folks, for if everyone in the USA decided to use Energy Star windows or even weatherstripping and caulk up for most sake. Again, for it’ll save more than $35 Billion in energy bills.

Because the amount of energy lost by windows is too tremendously big to not consider that: Period!

Furthermore, the DOE states that the average American household spends between $1,500 and $2,000 every year on energy bills.

Also, it estimates that 45 percent of that amount spent on heating and cooling. Most of heat and cold that is lost can be attributed to windows. That’s whether they are old and aged or they are simply woefully unsuccessful models of energy efficiency.

Energy Goes Out The Window

How do windows “lose” energy? According to the National Fenestration Rating Council (NFRC), in winter, poor quality windows that aren’t well insulated. For they create drafts in the home.

Therefore, these inefficient windows create the feeling of a draft. All due to changing air temperatures. Because warm air near a cold pane of glass. You know how it will quickly cool and then fall. Thereby creating a cycle of moving air. Moving air generally creates, as a result, a cooling effect.

In summer, it’ll seriously take time to efficiently cool a room. Therefore that’s a window with poor window quality.

That’s because the sun is able to directly influence and heat the temperature of the room.

So combating the problem of energy loss is a major issue for home and business owners. That’s especially in areas that are subject to extreme temperature fluctuations. That’s why a growing number of these consumers are searching. Searching for ways to improve their energy efficiency.

To help, a series of ratings exists which can help consumers decide which windows are not only the most energy-efficient, but cost-effective as well. These ratings adopted by the NFRC and displayed on all NFRC-approved windows. At the bottom of the post is a sample label with energy and performance ratings. Source: nfrc.org

About Energy Performance Ratings

U-Factor measures how well a product prevents heat from escaping a home or building. These ratings generally fall between 0.15 and 1.20.

The lower the number (factor), the better a product is at keeping heat inside. During winter months, U-Factor is a particularly important rating. Especially in colder climates. In other countries, U-Factor may be displayed in metric units.

Solar Heat Gain from Windows

Solar Heat Gain Coefficient (SHGC) measures the amount of heat from the sun that blocked by a window. Expressed as a number between 0 and 1, ratings closer to 0 show better blocking of solar heat gain. Blocking solar heat gain is particularly important during the summer cooling season in hot southern climates (www.nfc.org).

Windows with a lower (SHGC) can lessen the effect that direct sunlight can have on a window. It can also improve the ability to efficiently keep a room cool during warmer months. In contrast, people in northern climates may prefer a higher solar heat gain during the cold winter months. All to lessen the cost of heating a home. Overall, the windows with lower SHGC ratings will effectively lower cooling bills. That’s as well as reduce frequent temperature fluctuations.

Visible Transmittance (VT) measures the amount of light that is transmitted through a window. Like SHGC, VT is expressed as a number between 0 and 1. Therefore, the higher the VT, the more daylight is allowed to pass through the window.

Air Leakage

Air Leakage measures how much outside air comes into a home or building through a window. In addition, air leakage rates generally fall between 0.1 and 0.3. So the lower the air leakage, the better a product is at keeping air out. Also, air leakage is an optional rating. So some manufacturers choose to omit it from their labels.

Other important ratings to consider when researching potential windows include condensation resistance. Also water infiltration, structural performance ratings, acoustical performance ratings, and security performance ratings. Perhaps the most important is the product’s endorsement from the ENERGY STAR program.

ENERGY STAR

First of all, ENERGY STAR is a joint program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). Its official mission is to help consumers save money while protecting the environment through energy-efficient products and practices. The EPA and DOE set strict energy-efficiency guidelines for ENERGY STAR qualified products. In 2012 alone, ENERGY STAR helped Americans save more than $27 billion on their utility bills.

To become ENERGY STAR-qualified, windows, doors, skylights and other products must be independently tested and certified. All by the NFRC and labeled according to ENERGY STAR climate zones. Manufacturers that are certified ENERGY STAR partners tailor the components of their windows to work most efficiently.

Consequently and especially in these specific climate zones. These climate zones take into consideration typical energy usage and costs. They do this within their respected geographic locations.

Here is the official ENERGY STAR climate zone map:

Each ENERGY STAR-approved product is recommended for at least one of these zones. Furthermore, the second image shows the most recently-recommended criteria including U-Factor and Solar Heat Gain Coefficient for residential windows.

The HERO Program

To encourage energy-efficient homes, some utility companies offer rebates for home improvements such as installing new windows. Consumers are urged to check with their local utility company to find out about rebates in their area and to ensure that they are purchasing qualifying products.

Government-assisted programs like California’s HERO (Home Energy Renovation Opportunity) provide special financing opportunities to residential home owners as well as commercial property owners. So The HERO program offers 100% coverage of the costs associated with purchasing and installing eligible products.

In addition and also HERO, like many similar programs, offers low-fixed interest rates. Also flexible rates for most products (sometimes between 5 – 20 years) and the option to have repayments made through your property taxes each year.

Interest paid on the principal balance is also tax deductible.

There are currently over 150,000 products eligible for HERO financing. Windows make up a large portion of the eligible products and other items include doors, water heaters, lighting fixtures, flooring, and much more.

The HERO program ultimately lowers utility bills by lowering energy consumption and reduces harmful carbon emissions.

Play An Active Role
Energy efficiency is quickly becoming a top priority. Not for only homeowners and business owners but manufacturers as well. Installing new windows is easier than ever before, and with the help of local government-backed programs like HERO. Plus finding ENERGY STAR and NFRC-approved windows and other home improvement items is quite simple and affordable.

In conclusion, manufacturers are building their windows to exceed ENERGY STAR and NFRC requirements. Because to meet the rising demand of consumers who are actively taking part in energy conservation and purchasing and installing is growing. Yes folks, in goods like energy efficient windows.

Reliable companies also guarantee that all of their products are compliant.  You know, with the highest of standards. So they are proud to sell products that not only look great. However they help to save money as well as the environment. Replacing windows is one of the easiest as well as the most recommended ways to improve energy efficiency.
