There is a way to againt the global warming. You can start from your house. For more information, read this article.
Roof color is usually red brick, blue, black, dark green, and others. Very rarely do we see the white roof. For buildings with no cement is used to follow the color gray.
It turned out that for us who live in tropical and hot, the white roof will be much more useful.
Surface of the roof covering on average 25% of the entire surface of the city. Meanwhile, the streets covered approximately 35% of the entire surface of the city. According to the study of Hashem Akbari,
a researcher of the Heat Island Group, when the 100 cities in the world to replace the roof with a white color, and also the street with a more reflective material, such as concrete roads than paved roads, then the resulting global cooling effect would be enormous.
specifically for the use of the roof is black: a black roof can add to the hot temperatures at the surface of the roof. (It’s because like what we had learned in school, that the black color absorbs heat (heat) is higher compared to white color. It will also result in increased temperature in the room
nah, to reduce the heat, probably the least expensive way is to paint the roof using white paint.
why?? : It’s because the white roof to reflect ultraviolet rays more compared to a dark color like black, and can reduce heat transfer into the room.
even the state of California is requiring all new buildings since 2005, using the white roof, the roof surface for flat or declining
then what to do to paint the roof using white paint to the reduction of global warming?
it is because, the use of white roofs can save or reduce the use of air conditioning by up to 15% in one year.
it’s just for one house. then imagine if there are 1 million homes that save the use of air conditioning as much as 15% of each house it would probably be helpful for global energy conservation. consequently, could be slightly reduced heating globalpun
application of this white roof, but can save energy and money, it can also be of little help in the process of saving the environment
agan afraid of his peculiar plasticity if the roof is painted white?
This might be a little picture.
here are some examples of p-colored building with a roof
