California imposes white roofs for new construction.
According to the expert interviewed (presented as a shoe size), doing this for all buildings would be equivalent to removing half of the cars in circulation.

Ah yes, good idea of the last century and for poor countries, but today?
These Americans always at the forefront of progress in terms of energy consumption
They have not yet understood all the advantage they could get from the energy that strikes their buildings, whose surface of the facades is much larger and requires much more climialtization than rikiki roofs ...
As for small constructions, individual houses, even if they are sometimes flashy, they are quite rudimentary on the technological level (you have to see the requirements of their construction standards, you do practically what you want in them: that's what 'they should start by reforming ...) I don't know if you've been there, but when it comes to construction, these are really terrible colanders. With air conditioners that have an inverter producing heat using a resistor (no need to tell you all the electricity that it eats). Result: when it's hot, it's always too hot, and when it's cold it still curdles!
Aaaah the "American dream" it has lead in the wing. In the building it's more like a nightmare. I understand that such a measure may be appreciated there. Because in a way it is still a "luxury" within their reach! An emergency measure to deal with the most urgent. This is what leads a country where Sarkozy-style ultra-liberalism has reigned almost always! And despite being under this model, it is the most indebted country in the world! You speak of a model of democracy!
So hey, if it can amuse them to repaint America white ... I doubt that is the right priority, but the Skull & Bones will like it! And that proves one thing: it's a country "developing».

Ah the French (or Swiss, I don't know)! Always giving lessons!
We will see what the French will do in the next 5 years in terms of the environment!
For the moment, we are content to take care of the week of 5 days at school and the 2 weeks of vacation at All Saints!
Yupi, that was the urgency!

Where do you see that lessons are given? Have you ever been there?
It's just a statement of the facts. From someone who went there on a study trip and who knows the SIA building standards as much as he saw with his own eyes the Yankee constructions and lived there from New York to San Francisco ... ( it was the same thing but it was the same ...)
That European standards have nothing to envy to the one in force there is just the reality of the facts. They would do well to take inspiration from the Canadian model (that's a lesson!)
Painting constructions in white? It is about time they got started! The Arab countries, which they present as a sub-civilization, have been doing this for several centuries.
Mebon, it more impresses to have gone to the Moon with the money they looted elsewhere in the world. But the party is over.

Or ? Above.
Yes, I have been there too. And, by deducting "55 years" and "study trip", it is more recent. And, no, they're not perfect. However, we can talk about good things.
Yes, many countries have white roofs, but not "rich" Europe.
So it's good to talk about it here.

Pfff! What a revolution! ...
At the North Pole too?
In my house, there is a black roof, and that is as much heat recovered when there is a bit of sun.
In summer, it's more like the bread oven, but we do it without air conditioning.
The hot season with us has been rather rotten for a few years .... So ... the problem is different.
The idea of generalizing white roofs around the world to save half of the carbon emissions of cars around the world is an understatement.
It all depends on the climate.
Local tips.
And air conditioning is not practiced worldwide ...

No, but it is spreading at high speed
Too bad there are no progress figures, but:
http://www.developpement-durable.gouv.fr/IMG/pdf/Rapport_clim_Art5_LG1_280811.pdf a écrit :The fleet of air-conditioned buildings is still small, but it is constantly increasing in the
tertiary sector, and rapidly developing in the residential sector.

It's not just white roofs.
A friend of mine noticed that his photovoltaic panels (fitted mounting) put his roof in the shade and significantly lowered the temperature in his rooms in summer.
