California: American scientists have invented a white color that reflects 98% of the light and heat coming from the sun. That is, if this color is applied to a building, it can stay cool inside even in extreme heat.
So far, the typical white paint on buildings has the ability to reflect up to 85% of sunlight, meaning they absorb 15% of sunlight and heat. This keeps them warm in extremely hot weather, as a result of which these buildings also heat up considerably from the inside, which requires air conditioning arrangements to cool them.
