The YKKAP Shinagawa showroom is amazing!!

I had the privilege of visiting the YKKAP Shinagawa showroom, which will be reopening on June 5nd. I've been to many showrooms, but to be honest, this one was the most mind-blowing. In a vast man-made space that is kept at minus 55 degrees Celsius all year round, there are five rooms of about 20 tatami mats each with different insulation levels. There are five levels: 1 level, next-generation energy-saving level, HEAT2 G5 grade, GXNUMX grade, and passive house level.

Each room is equipped with a wide-angle thermography camera and a large touch-screen display measuring over 40 inches, allowing you to compare the real-time thermography of your room with that of one of the other four rooms you wish to compare side-by-side.
I don't think you'll find a more realistic simulator anywhere in the world. Professor Iwamae and Professor Mae have already seen it, and Professor Mae, in particular, is close to the University of Tokyo, so I think it will be a great teaching material for students to use in their research.
Also, being able to experience the actual difference that cannot be seen through simulation alone is very important. I don't think there is a facility that is as easy to understand as this for persuading construction companies that are like, "I don't understand the logic, but I'll go with my instincts." I would like all practitioners who read this to visit the facility at least once.
There were two other things worth seeing. The first was a remodel-compatible window called "Madrimo." Until now, when it came to remodel-compatible windows, the standard was an inner sash. However, double-opening the window was a hassle, and it didn't solve the problem of condensation on the inside of the outer window. It was also true that problems such as poor opening and closing due to damage to the outer window remained. The new Madrimo solves these problems.
I knew the product name, but honestly I didn't have high expectations until I saw it in person. However, when I saw it in person, I was convinced that "This is the window renovation of the future!" Here's why.
・If you remove only the shoji screen (movable part) of the existing window, you can install it inside the existing frame. Therefore, there is no need to destroy the exterior wall or waterproof layer. In addition, attachments for the appearance of the joint and waterproofing are available for both the exterior and interior.
・Construction can be done from the inside without the need for scaffolding. This has enormous cost benefits.
・Opens and closes in one go, eliminating condensation problems
・Previously, I think these types of products would have been commercialized at best as plastic aluminum products.
However, this time it has been commercialized by repurposing the high-performance windows APW330 and 430. I think this also gets to the essence of the matter.
From now on, new construction will certainly decrease. And the baby boomer generation will enter the late elderly stage. Most of them live in homes with low or no insulation. I think that from now on, products like these windows will need to be adopted at a rate of more than one million homes per year.
I believe that for all the practitioners who have read this, this is currently the best option for them if they are planning to undertake a renovation in the future.
Finally, I saw the front door, D50 (U-value 70) and D70 (U-value 50). Although the performance of windows has been steadily improving for several years, the front door, which is the face of the house, has been lagging behind. Therefore, I often had no choice but to use foreign-made front doors, but it felt like a domestic front door that could be used with confidence had finally been released. DXNUMX uses real wood and has an extremely high quality feel, but the price is also quite high... it seems difficult to use this as a standard. On the other hand, DXNUMX looks closer to the conventional Venato and is within an acceptable price range, so I think it will become the main one from now on. If the windows are from APW, I think DXNUMX is a good balance for the front door.
So, I thought it was a showroom with a strong sense of community that I couldn't help but visit after it opened. I can honestly say that it was the most impressive showroom of all the building materials showrooms I have ever seen.
