(WIBC Indianapolis)   New 'super-white' paint that reflects 95.5 percent of sunlight off buildings is so good at reducing heat it could one day replace air conditioning. Subby would like to have them test this in Houston during the month of August   (wibc.com) divider line

Fingerware Error: The difference is in the paint's recipe: it's filler is calcium carbonate, a compound found in rocks and seashells.

Sounds like a whitewash to me.

The paint is white in color, non-toxic, and it can be sprayed or brushed like any other paint. The difference is in the paint's recipe: it's filler is calcium carbonate, a compound found in rocks and seashells. The paint also has layers of particles that are different sizes, which allows the paint to defend against a wider range of sunlight wavelengths.

Sounds like a chemical to me! I don't like chemicals! I only use organic free-range paint.

Unfortunately I have to close my eyes and feel around for the door handle to insert the key in. Long ago, my eyes fried outta my head when I took a good look at my place at the wrong time of day.

dittybopper: Difficulty:  its manufacture depletes the ozone and exposure to it causes birth defects, cancer, and a predilection for listening to show tunes and performing jazz hands.


Well, that explains a lot...

Target Builder: In infrared it looks like this:
[buildingscience.com image 225x300]

Yup. They built an 80 story heat exchange in the middle of a city noted for cold winters.

But because of how building energy sustainability scoring was written at the time, focusing on avoiding heat gain, it scored very well. The rules have since been changed.


Everything about that building, from an energy perspective, is a huge lesson in what not to do.
I'm an architect with a specialization in building envelope science, practicing in an even colder climate than Chicago. If you want lessons on how to reduce energy costs in buildings, look up north - we've been the experts for 50 years - and this white paint stuff is nonsense.

Could you imagine trying to navigate a city of buildings painted like this in the middle of a clear day?

No thanks.
