Park It can be Odyssey in some cities. But the worst is not the time that is needed. The worst, according to a study recently published by Portuguese scientists, is that you may prefer to give Heat accumulation In the neighborhood, where you finally managed to park. Especially if your car is Dark color
According to this study, parked cars contribute to phenomena known as Heat islandswhich explains why in general in Urban environment A kind of microclimate is generated, in which the temperature usually suffers much more than usual.
The main perpetrators of the formation of the islands is the heat, according to previous studies, are asphalt, buildings and lack of green areasHowever, according to this last work, the field, parking on the street can make a contribution a lot. So much so that their authors believe that very specific measures should be taken in order to avoid this.
What islands are warm?
City Islands – urban areas, usually with many designs that are wonderful warmer than the surrounding rural areasThis, how we advanced, is usually connected with the presence Asphalt and buildingsas well as with Lack of green areas.
Asphalt, both for its color and for its composition, Absorb very warmlyThus, it remains on the ground, doing what that happens is hot. For their part, buildings are usually made with Materials that also absorb very warmly. When they are painted white, it is possible to reflect part of this heat, since the white surfaces reflect most of the radiation, unlike the dark ones that absorb them. This is due to the fact that Black said very briefly, a mixture of all colors, and white is their absence.
All waves of sunlight corresponding to all colors are absorbed by something completely black and are reflected in something completely white. That is why it is in recent years that the production of colors. No, the target goal, which is usually used, is not complete and completely white.
Even white buildings absorb heat, so that, next to the asphalt, it concentrates a lot around him. To top it off, the absence or lack of green areas do not help. Plants have the ability absorb water with its roots, and then release it in the form of steam through sweat. This causes an effect similar to the effect of microsres that are placed in the summer on the bars terraces. It generates cooler micro -inflection. Therefore, if there are few plants in this area. Now that all this should park on the street or not?
The harmful effect of parking on the street
Cars consist of Metal structures that absorb very heat. Yes, to complete this, they are black or dark colors, They absorb even more solar radiation. Consequently, the authors of this study suspected that park cars on the street, the effect of the island could be increased.
To check it, They parked a black car and another white car In the city region with the asphalt of Lisbon. They left them there during the sunny hours of the day and measured the temperature before and after. Thus, it was clear that the air temperature around the cars, especially in the case of black, increased greatly.
With a dark machine was increased 3.8 ºCThe field in the case of whites was the greatest increase in the degree lower, but an increase in temperature was equally. After analyzing the data on parking and traffic in Lisbon, they saw that parking on the street could be very harmful if the effects measured in one car were extrapolated to the real figures of the Portuguese capital.
Measures must be taken
Despite all this, the authors of the study believe that in some places where the effect of the island of thermal islands should be more acute Prohibit the parking of a black vehicleThe field also more shadows should be provided, So when the parking lot does not affect it so much. And, of course, the method of using the materials by which the part of this heating should be used.
Of course, the ideal is to convince all drivers to buy clear cars, but this is impossible. Now, if you thought about getting a new car, and you are worried about the heat of your city, you can always put your sand grain. Your neighbors will be grateful to you, but you will also do it.
