Thank you, Mr. Jowhari.
Our solution basically applies to both retrofits and new construction. As we build more and more high-rises and more buildings, we are using concrete as architectural surfaces. That's one of the highest carbon-embodied materials you can use, as compared with the technology in solar, which has among the lowest carbon-embodied profiles.
At the same time, our point of view and our glasses to this world is that we integrate more solar into the materials that are in touch with the sun. Our building walls, our building windows or the roof are all in the line of solutions that we have created, and they're all applicable to the retrofitting of buildings that you mentioned from the 1970s and 1980s as well as to new construction.
One issue that we're going to face in the coming years is that all of those people who are living in older buildings won't have access to the EV markets, because these buildings are not designed to have more electricity, and it is the solution that we have. This is the key point, integrating more solar into the building materials and using it in retrofit and new construction, and we keep it in mind. We know the cost and we know the aesthetics and we know the installations. Those are all barriers to entry that we have had in the past many decades. It's why these products haven't been developed.
This is part of our solution—the retrofit and the EV market that's going to be connecting all of these buildings and charging all of those cars in the coming decades.
