What You'll Learn
Park in the shade
Parking in the shade is one of the simplest and most effective ways to keep your van cool without electricity. This is especially true in the desert, where parking in the shade can lower the temperature inside your van by ten degrees or more. If you're in a hot, sunny location, seek out natural shade from trees or other vegetation. Coastal areas, river corridors, and higher elevations tend to be cooler, so consider parking near these spots. If you're in a dry, sunny area with little natural shade, such as a desert, consider investing in a large, affordable tarp or an awning to create your own shade. You can also use tarps to rig up a shady spot to relax under while still taking advantage of any available natural shade. Just be sure to use tree-friendly straps, such as wide nylon, to avoid damaging any trees.
When parking in the shade, orient your van so that its windows aren't directly facing the sun. This may require adjusting the van's position throughout the day as the sun moves. Windows have no insulation and will allow the sun's heat to pour into your van. If you can't park in the shade or adjust your van's position to avoid the sun, consider using blackout curtains or insulated window covers to block out the sun's rays. These window coverings will help keep your van cooler by preventing the sun's heat from entering through the windows.
While parking in the shade is a passive cooling strategy, you can also take active measures to enhance the cooling effect. If it's safe to do so, leave your van doors open to maximize airflow. This will allow hot air to escape and be replaced by cooler air. However, be aware that leaving your doors open may result in insects entering your van. If you need to keep your doors closed, consider installing vents and fans to improve airflow and circulate cool air. Simple unpowered fans are affordable and effective at moving warm air and creating a breeze. You can also use battery-operated or 12V electric fans for more powerful airflow.
In addition to parking in the shade and improving airflow, there are other strategies you can employ to keep your van cool without electricity. Proper insulation is key to maintaining a comfortable temperature. Opt for insulation with a high R-value, and ensure it is installed properly without thermal bridges. Reflective insulation on your windows can also help by reflecting up to 97% of the sun's radiant energy away from your van. Solar panels on your van's roof will provide shade while powering your electronic devices. Finally, remember to stay hydrated, especially during those scorching summer days. Drinking plenty of water is crucial to preventing dehydration and heatstroke.

Planning a route through areas with cooler climates is a great way to keep your van cool without electricity. Here are some tips to help you plan a route that will help keep your van cool:
Plan your route along coastlines – Driving along the coast can provide a cooler climate due to the presence of ocean breezes. Aim to stick to highways as they are typically better maintained and equipped to handle extreme heat.
Head to mountainous regions – Higher altitudes offer colder temperatures. Consider planning your route through forested mountain areas to benefit from the shade and cooler air.
Check the weather – Before embarking on your trip, stay updated with the weather forecast. This will help you anticipate any extreme heat waves and plan your route accordingly.
Be flexible with your itinerary – Allow yourself enough time to make adjustments to your route as needed. If possible, avoid travelling during the hottest parts of the day, and consider taking breaks or even stopping for the night in areas that offer shade or cooler temperatures.
Pacific Northwest – A popular route for those seeking cooler temperatures is to head to the Pacific Northwest during the summer months. This region is known for its milder summers, offering a respite from the heat.
By incorporating these strategies into your route planning, you can effectively keep your van cooler without relying on electricity. Remember to also maintain your vehicle, especially by checking coolant levels and tire pressure, to ensure it can handle the journey without overheating.

Use vents and fans
If you want to cool your van without electricity, using vents and fans is a go-to solution. There are a variety of options to choose from, including simple unpowered fans, battery-operated fans, or 12V electrical fans. These fans can be placed near open windows to promote hot air leaving the van and cooler outside air entering.
One effective way to use vents and fans is to create cross-ventilation in your van. You can do this by opening doors and windows, especially if they have screens to prevent insects from getting inside. This allows for airflow throughout the van, keeping the space cool. Additionally, consider installing a pair of powered fans with dual intake and exhaust capacities to maximize air circulation. One fan can be set to pull air in, while the other pushes air out, creating a constant flow of air.
Another tip is to use a fan in combination with a wet cloth. By placing a wet cloth over a fan, you can create a low-cost DIY air-conditioning effect, helping to cool the air inside the van. This can be especially useful in dry heat conditions.
When using vents and fans to cool your van, it's important to ensure that the van's orientation is considered. Keep oversized windows facing away from direct sunlight to minimize heat entering the van. Additionally, if you have the option, parking in the shade can significantly impact the temperature inside the van, making it much cooler.
While vents and fans can be effective, there are also other strategies to consider for keeping your van cool without electricity. These include parking in the shade, using awnings, and minimizing the use of heat-emitting electronics inside the van. By combining these strategies with the effective use of vents and fans, you can create a comfortable and livable space in your van, even during hot summer stretches.

Insulate your van
Insulating your van is an important step to keep it cool in the summer. Insulation doesn't just keep you warm in cold weather, it also keeps the heat out when it's hot.
There are various ways to insulate your van, and the best method, in my opinion, is to get spray insulation done by a professional. They will be able to fill all the crevices in your van, keeping you cool in the summer and warm in the winter. If you are insulating your van yourself, you can use Thinsulate insulation in the front cabin ceiling and door panels. It's important to fill any crevices as air can easily slip through and make your van damp and cold. You should also insulate the floor of your van, as this will help keep the heat out.
Another important aspect of van insulation is the windows. Windows have no insulation and will allow the sun's heat to pour into the van, so it's crucial to cover them. You can use window covers, such as the ones offered by Van Made Gear or Wanderful Window Covers, which fold up accordion-style when not in use. Alternatively, you can use blackout curtains cut to the size of your windows.
To maximise the cooling effect of your insulation, you should also consider parking in the shade, especially in hot climates like the desert. This can cool your van by ten degrees or more. If possible, orient your van so that the windows aren't facing the sun, and adjust its position throughout the day as needed.
While insulation is key, you can further enhance the cooling effect by installing powered fans with dual intake/exhaust capacities to maximise air circulation. Simple unpowered fans can also help create a breeze and improve airflow, especially if you can safely leave your doors open.
