How To Keep A Room Cool That Faces The Sun

If you happen to have a room facing that you need to be cooled, you’ve come to the right place. One crucial factor you need to note is that the best way to keep a room cool that faces the sun is to keep heat out of it. There are many options for keeping a room cool, with the main one being the use of an air conditioner.

However, that can be costly and inefficient because air conditioners may increase your electricity bills, and they are not always environmentally friendly.

Although you want to cool a room that faces the sun, you should note that it’s beneficial to have such a room because it lowers heating costs during the winter due to the additional solar heat. Unfortunately, it can be unbearable to stay in a room that faces the sun during the summer.

10 Best Ways on How to Keep a Room Cool that Faces the Sun

So, how do you keep a room cool that faces the sun? Here are some of the simple and efficient ways you can do that.

1. Install Heat-Reflecting Film

One of the best ways to prevent heat from getting into a room that is directly facing the sun is to consider installing heat-reflecting film. This is quite similar to tinting your car and works perfectly to prevent the heat from the sun. 

The benefit of this method is that the film is not expensive, and it also helps to reduce the glare from the sun. What’s more, you only have to apply on windows you want and not the ones you want to receive the sun from during the winter.

2. Consider Using Drapes and Curtains

The second option involves using drapes that have a white side facing the window. The reason why it needs to be white is that it will reflect the sun. Therefore, you can pull the drapes when the day is too hot to keep the room cool.

Curtains also enable you to control the amount of sunlight entering a room. Therefore, if you decide to keep them closed, it helps to block the light and heat that comes from the sun. This way, you’ll be able to keep a room cool that faces the sun without having to strain too much.

3. Use Awnings

Awnings are also known to help control the amount of heat entering a room. Although awnings don’t affect the temperature directly inside a room, they can help ventilate your home when the humidity level is too high.

You also have the option of keeping your windows open during the day to ensure cool air enters. Awnings also provide a shade to protect you from direct sunlight and enjoy a cool breeze.

4. Go Natural and Grow Shade

This is probably not an option that many people prefer because it doesn’t offer an immediate solution to cool a room that faces the sun. This is mainly because it takes longer to solve the issue.

After all, it involves growing trees strategically placed to shade your windows and keep them cooler. It’s a long-term solution that takes years for the trees to grow but can be quite beneficial once that happens.

5. Try to Reduce Humidity

One notable way of keeping a room cool that faces the sun is to reduce the humidity level. There’s a higher chance that you’ve heard people blaming humidity instead of heat when it starts to feel uncomfortable outdoors. Therefore, you should also note that high humidity levels can make a room feel even hotter. 

You can lower the humidity level in the room by using a dehumidifier, which will provide you with a cool breeze and a comfortable experience. When using a dehumidifier, try and ensure the humidity levels are between 30 and 5 percent. This will help keep you comfortable, and you can also consider running exhaust fans in your kitchen and bathroom to reduce the humidity levels.

6. Consider Using Fans

Another option, perhaps one of the best solutions to consider, is using fans. That includes using ceiling fans because they help draw cool air from the floor to the ceiling, usually where hot air hangs. You can also consider using box fans or window fans in the evening to push out hot air and draw in cool air from the open windows.

7. Consider Lighting

Since a room that faces the sun tends to have more sunlight coming in to brighten it, it’s unnecessary to use heat-generating bulbs. Therefore, you need to consider turning off the lights during the day to prevent air conditioning systems from overworking. When there’s less light entering a room, it will help make your AC unit work efficiently and even help you save costs on energy.

8. Use Energy-Efficient Windows

If you happen to have a room facing the sun that you need to cool, you also need to consider installing energy-efficient windows. The benefit of this method is that it will help keep the sunlight without affecting the temperature inside the room.

These are energy-efficient and double-pane windows because they help to reduce the heat and still provide natural light. Additionally, having a lower indoor temperature will reduce the work of your air conditioner, thereby making it able to keep you cool properly.

Pro Tips

There is also the option of considering window treatments. This involves using a light-colored or reflective backing since they are known to work perfectly. Adding a window treatment also helps to add beauty to your interiors. 

Another pro-tip is to limit heat-generating activities in your room/home when the weather is hot. For instance, you can cook outside on a grill or replace incandescent bulbs in the room because it adds heat. 

You should also check the entire room to ascertain that there aren’t any air leaks where cool air may escape.
