Why Underground Parking Areas Are Hot

You might assume that underground parking lots would be fresh. Unfortunately, that is not the case.

There are plenty of reasons for this. Below, we will be going over some of the different reasons why underground parking areas get so hot.

Reasons Underground Parking Areas Are So Hot:


One of the reasons parking lots underground are so hot has to do with what is being stored in them. The fact is, a parking lot meant for vehicles. Because the majority of these vehicles are warm themselves, they give off a lot of heat. Therefore, it can cause warm air to take up the garage.

Exhaust Fans.

Another reason it gets so hot in the parking lots that can be found underground have to do with the exhaust fans that are needed throughout the garage. Because CO2 permeates throughout these garages due to the exhaust fumes, the garages require a lot of high-intensity exhaust fans which can give off a lot of hot air.

Driving Vehicles.

Another reason has to do with the fact that a lot of vehicles are actively driving throughout the day in these garages. Because of this, you are going to have constant exhaust fumes and hot cars, causing the air to heat up. This makes the entire garage feel much warmer as a direct result. The longer for the vehicles to park or exit because of a lack of parking guidance solutions, the hotter the parking area becomes.


Garages typically do not have a lot of places for heat to escape. Because of this, the parking garage can heat up and cause the hot air to get trapped itself. This can cause the garage to feel much warmer than it should be.


Concrete is known to retain a lot of heat and allow heat to enter. Because of this, a hot day can cause the garage to heat up, and because garages cannot get rid of hot air quickly, it ends up increasing the overall temperature.

Now that we have gone over some of the reasons parking garages can get so hot, we will go over some of the ways to cool it down.

Ways To Cool Parking Garages Down:


One of the ways you can cool these garages down is by investing in fans. By running fans at night, you should be able to get more air moving throughout the day. This will allow the garage to expel hot air much quicker, and it can help with overall circulation, which should make for a much more comfortable ambient temperature.

Open Air.

Another significant way to help cool down a garage that is located underground is by making it open-air parking. You can do this by allowing air to have plenty of room to escape. Because hot air rises, you could have portions of the garage opened to allow for the heat to escape easily.

Overall, there are plenty of different reasons these garages get so hot. There are specific ways you can cool them down, but underground parking is likely always to be reasonably hot.
