You must pay attention on energy efficient windows if you want to live green
In order to save our planet, we must pay attention on many things. One of them are windows. Maybe you believe that there is no need to replace your windows or to spend a lot of time on choosing the right one, but they are important for green living. You probably know that the best choice is energy-efficient windows. But, you should be careful when you choose them. Luckily, you can use a NFRC (National Fenestration Rating Council). Their labels can help you compare the energy performance.
The two, most important things, you must pay attention on are SHGC (Solar Heat Gain Coefficient) and U-factor. If you truly understand both of them, you will use less energy to heat or cool down your home. This is important for green living. U-factor means how well a window is in preventing the heat from leaving the building. It is rated from 0.09 to 1.20. The lower the rating, the better the window. SHGC measures how well a window is in preventing the sun’s heat from entering into a house. It is rated from 0 to 1. The lower the rating the better.
But, it is important to talk with a professional before you go to the shop. Which windows are the best for you, also depends on your climate. Different climates, require different windows. However, all of them are a wise choice if you have old windows or a lot of air leaks.
This simple upgrade will help you use less energy. This is an important part of a green life. Probably the most important.
