I’m just referring to Jensen Huang’s presentation in the video above.
It starts with “Every house starts with an idea. Getting from idea to design (whatever that means) takes a myriad of tools, expertise, and a lot of time. Now an ai agent…”
If possible, I try to dodge classical 2D drawings. They are kind of hard to fully automate by a script and take a lot of time. Many manufacturer can direcly work with stp files. For the different stones, I provided measurement lists in combination with scheme drawings. Usually its the best to customise the fabrication data in exchange with the manufacturer.
Reasons why this kind of fins are added in many architectural projects:
Looks “cool”, expensive (for sure it adds to the cost) and different to many people;
Partial shield against the Sun in warm days;
Helps against small drone attacks;
May help if somebody tries to break and jump through the windows (not guaranteed for fit people, but the biggest fans of “McDonald’s” are secured for sure);
Makes it far more difficult for somebody watching from inside to be seen from the people outside, especially at an angle (good hiding place for James Bond 007 during a chase).
Negative impact:
As mentioned above, it makes the project more complicated and expensive for the sake of looking complicated and expensive (just like most modern cars with ton of random creases, fake grilles and other details that exist for no other reason);
Increases the bills for heating during the Winter, and also requires earlier turning of the lights inside, further increasing the electricity bills;
Increasing the wind noise (makes the winter more memorable);
If not secured properly, some fin may fall and do damages or even injury to somebody near the building;
Catches more dirt, thus the cleaning must be 10 times more frequent, requires a special equipment and is way more expensive.
Since I did not work on the architectural design, I do not want to elaborate on or defend the design in detail. However, there are many areas in the building where the pilasters create outdoor spaces and terraces. I think reducing the pilasters solely to sun protection would be somewhat simplistic. If I imagine the building without the pilasters, the overall architectural impression would be completely altered.
vertical fins have lingered around the facades of buildings and cities for ~70 years.
for whatever brain-dead “aesthetic” motives, buildings “must have” fins in order to be Modern™ or else the building looks Ugly™ to certain designers - typically the cosmopolitan types found in NYC, LA, LON etc. the worst offenders are fins that protrude from the building by no more than 100-150mm and are spaced ~1500mm. they do nothing beneficial for thermal environment of the city or building (since they are not ever [okay rarely] connected to thermal mass of the building, they don’t work like heatsink fins*); they cost large sums of money that could arguably be better spent on other parts of a building with a far greater impact on the human experience; they are superficial - icing on the cake - visually interesting if only for a couple seconds before which is about equal to the attention span of most people today; and they will be seen poorly by later generations, if not just totally removed from buildings (akin the funny collars worn by european elites in the 16th -17th centuries; they were status symbols, but we laugh at how goofy they look in paintings now)
the cons vastly outweigh any benefits - unless you’re in the desert and your site has extensive east and west exposures, but even then you better be okay with all the dust/garbage/cobwebs that will accumulate on them + the mediocre quality of daylight that occurs because of the zebra-striping.. the anti-drone resistance is a new perspective though
* i am aware of “carbon-capture” paints which are effective in storing CO2, but the amount of CO2 locked in place is a drop in the ocean compared to the amount of CO2 needed to produce every other part of the building and the electricity to operate the building. plus paint needs to be maintained more frequently than resilient materials like your stones/marbles/bricks/metals
tldr: fins are dumb, and i’m disappointed that so many of my architect colleagues continue to use them as an element of “performative architecture” or “high-performance architecture”
