Every home has windows; their placement will decide how much light and breeze they will let in. Though you may enjoy keeping the windows open at some times of the year, there will be times when it’s either too hot or too cold to do it. This is when you should shut them and use either the heating or cooling function in the HVAC system.
The fact is that heat that transfers through the windows can easily account for 10-25% of your air-conditioning and heating costs and the biggest culprits are the older, single-paned ones. The one way to prevent this from occurring is to replace them with double-paned energy saving windows. Though the latter isn’t going to be very light in your pocket; the long-term benefit is that they can reduce your energy use by almost 30%.
Aspects to Consider
If you opt for Energy Star-rated windows, these are twice as energy efficient as the standard models that were sold even up until a decade ago. So, how exactly do new windows save energy and what are the factors that determine this aspect?
- Solar Heat-The SHGC (solar heat gain coefficient) of a window (a value that ranges from 0-1), is an indicator of the fraction of incoming solar radiation admitted via a window. A higher number means a greater amount of heat will get transmitted; energy saving windows have a low coefficient and this means they have low heat gain.
- Heat Transfer- The heat transfer rate between the indoor spaces and the outside of your home (which isn’t related to solar radiation), is called the U-Factor of the window; typically, this ranges from 0.2-1.2. A lower value indicates a lower heat loss from your home. This is very helpful in the winter months. Today, it’s also possible to buy double paned energy saving windows that contain argon. This inert gas is “sandwiched” between two panes and helps minimize heat transfer.
Glazing- New energy saving windows are coated; this helps reduce heat transfer. Low-E (Low-emissivity) coatings that are made of microscopic metal particles are effective in bringing about a 40-70% reduction in heat transfer, even as they allow most of the light to filter through. It’s also possible to opt for reflective/tinted glass; however, these variants also block a certain amount of incoming light.
