Passive Cooling: What Is It?

The heat is a significant problem for many homeowners and renters. Many places have exprienced shifts in temperature that have made them hotter or that have a tendency to experience a lot of warmth during specific seasons. The problem with this is that many people spend hundreds on air conditioning to keep cool or have to surge up their electric bills to keep their homes at a suitable temperature. The new trend for coping with this issue is passive cooling that can save you money and can keep the home comfortable without the need to worry too much about air-conditioning or investing a lot of money. Let’s take a look at what passive cooling is and how you can apply it in your home.


What’s Passive Cooling?

Passive cooling refers to a set of strategies that can help you reduce the temperature of your home by organizing and employing specific materials or tactics. It means cooling down the place by means other than air-conditioning. Once you have designed your passive cooling strategies, it is free to employ them, because these tactics used change the organization of your home, shading, insulation, materials, and other things that can be done once and then used as a long-term strategy. The benefits of this strategy are clear. First, it saves money on bills and air-conditioning, which requires the purchase of expensive equipment and installation. Secondly, it provides additional cooling strategies even if you do have air-conditioning, so you can save power and reduce the overall temperature of your house. For places that get especially hot, this can be highly beneficial.


What Can You Do To Reduce Overheating?

Now that we have defined passive cooling and its benefits, let’s talk about the specific strategies you can use to implement it in your home. First, consider whether you want to apply it to a new place, after a renovation, or to your existing home. It’s possible to do all three but if you choose to implement passive cooling while doing significant rehauls or to a new place, you might be able to go further. For example, planning for cooling when you build a home can guide your choice of materials, which you can’t do when working with an existing apartment. Here are some general strategies that you can consider to cool your home:



Fans, openings, and windows can be used to create a nice flowing breeze that comes through your house. You generally want to consider this at the planning stage but you can improve the ventilation in your home by changing the placement of fans and opening or closing windows strategically.



An important step is to protect the windows. By tinting or coating the glass, you can reduce the heat that enters your home. There are many different options you can choose from, and glazing is a low-cost option for keeping out the heat. The one downside is that a glazed window will keep out the warmth in winter as well as in summer.



Shading provides a more customizable alternative to glazing. There are hundreds of shading options for your home that can block out the sun from your window, protect your walls, and be utilized in other ways to prevent the heat from building up.  Shading is a topic all in itself but you might consider available options, including shades, curtains, external shading, and others.



Insulation keeps the heat in and out depending on the season. This can be done by changing the color of the roof, putting plants on the walls, and also glazing. Insulation is another thing better implemented at the planning stage but you can easily renovate your house to have a more significant ability to keep heat in.


You can add to these main strategies by having plants and water in your home, installing fans and AC to be used as needed, and generally being mindful of the heat. Just keeping the shades closed can make a difference in the temperature of your home.
