Window Orientation for Replacement Windows in Scottsdale, AZ

Replacing windows can be a huge investment, and something you want to get right the first time. But how can you decide which options are best with the different style and material options available? Not to mention all of the conflicting advice you get. Here is some advice that will make your efforts a little easier if you are looking for replacement windows in Scottsdale, AZ.

Things to Consider

When it comes to new windows there are a number of things you need to think about before choosing. First you need to think about where your home is built and the climate of the surrounding area. Then homeowners also need to consider how the home is positioned on the lot. That can get a little more complicated. So here is what you need to know:

1. South-Facing Windows

Because of the patterned movements of the sun, these windows are often well suited for allowing in solar heat in the winter. There are different types of glazes you can use on the south facing side that help absorb the sun’s heat and cut down on your heating bills during the colder months. The number to watch where is the solar heat gain coefficient (SHGC). The higher the number, the more heat from the sun passes inside. Also, in order to keep the heat inside once the sun goes down, experts recommend double paned glass so the window stays insulated. Southern facing windows also let in the most natural light and can work to lower energy use in that way. However, in Arizona, there are mild winters and scorching summers. So you will want to find proper window coverings for this glass during warmer months.

2. North-Facing Windows

These do not bring in the warm, direct sunlight. Instead, they emit a cooler, softer natural light—great for the indirect light. The sun hardly impinges on these windows aside from early morning or late afternoon glimpses in the summer. At these times the radiation gets reflected off the glass or blocked by walls and eaves. Not to mention the north wind is usually the coldest. Thus these are the best windows for cross ventilation in the summer.

3. East-Facing Windows

These windows receive both light and heat, and are difficult to shade from the summer sun as it rises in the morning. The east-facing windows welcome in morning sunshine. This is nice to chase off the nightly chill. However, the direct light makes these windows especially difficult to shade. Often the angle of the sun is low in the morning and afternoon, bringing in the unwanted heat in the summer. You might consider some toned glass or a high performance glazing. This will keep heat and light from the direct light down.

4. West-Facing Windows

Conversely, west-facing windows are the biggest energy losers. These close out the day and in the summer these windows overload the home with heat. Not exactly something you look forward to during the hottest time of year in Arizona. For these windows, it is best to use multiple panes and gas fills to insulate. You also want glazing that provide built in shading and a lower SHGC. To keep things cool in rooms with west facing windows you might also require outdoor trees or wide overhangs to block the outside sun.
