New Building In London Reflects Sun And Melts Cars

An interesting development in London today. A new building due to its design is causing extreme heat to be reflected off the building onto cars and shops below.

Walkie-Talkie Skyscraper Beam 'Melts Cars'

Blinding rays of light from a skyscraper in the City of London are being blamed for melting vehicles below it.

Developers of 20 Fenchurch Street, better known as the "Walkie-Talkie" because of its distinctive shape, are investigating reports of the damaging glare, and a number of nearby car parking spaces have been suspended, say reports.

Businessman Martin Lindsay said he was distraught when he returned to find his luxury Jaguar XJ saloon with warped panels along one side.

The wing mirror and badge had also melted from the heat of the reflected sunlight, he claimed.

Holidaymakers at a new hotel in Las Vegas have been left with severe sunburn after the building's windows reflected 'death rays' onto certain areas around the pool.
The Vdara hotel has a concave shape which reflects the blistering Nevada sun from its all-glass front and directly onto sections of the swimming pool area below
The result has left some guests with burns from the powerful rays and even plastic bags have been recorded as melting in the heat.

You'd think "don't use a giant sun-focusing parabola on the south, east, or west side of any building you design for the northern hemisphere" would be a maxim that would get imparted to architecture students at some point during their formal education.

From peripheral experience of architects, their philosophy would appear to be that they can design anything and it's up to other people to make it work so minor inconveniences such as their building cooking passers-by or melting cars don't enter the artistic process.

Proof positive that architects should be forced to live and work in, or in this case directly across from, the buildings they design.

It was the same architect, Rafael Viñoly, who designed both buildings.

The infamous Vdara "Death Ray". I didn't spend any time at the pool there when I stayed there a few months ago (It's a pretty nice hotel even though it was originally designed as a condo property.), and not because of the "Death Ray".

They tried to put a coating on the windows to cut down on the effect, but it didn't work too well. What's interesting is the guy that runs one of the Vegas sites I hang out on predicted the "Vdara Death Ray" a few years earlier based on looking at the architectural renderings of the pool deck he had been sent. They ended up placing plants and landscaping in strategic spots to mitigate the effect.

Ah, but those two buildings are his concept-proving prototypes.

and he's from Uruguay, in the southern hemisphere.

I'm sure he's very talented but I have a feeling he's going to end up responsible for some major building code revisions

This was my first thought too, as others have mentions it's even the same lead designer.

In *some* cases. Most of the time this is not true, but as with any profession there are sometimes egos bigger than their skill level or understanding. My suspicion here however is of an over-reliance on technology. This building will have been computer modeled extensively, where the most minor of adjustments separate failure from success. We've gotten to the stage where real world construction can't adhere to the computer world standards, so with a few panels out by a few millimeters the building's dynamic change and often there are unexpected results. My suspicion is that this 'death ray' is one of them.

In the story it states that the temp on the sidewalk was 92.6F, hot enough to cook an egg. Heck, that temp is very common in the U.S. during the summer months. What about the Jag's that get bought by the Saudi's? Do they also melt in the summer heat there too? Jaguar needs to make it's cars more temp resistant.

I think it's a tad different when the heat is concentrated on one point rather than it being the ambient temp, focus a magnifying glass on your hand and see how that goes, same principle I think.

Sure, in the summer we regularly hit 100+ in the Valley here in LA, but it's not concentrated into one point. My car sits in 90-100+ F for several hours a day, it doesn't melt. I could, however, probably fry an egg on the bonnet...

It would seem to me though, that the inside of said buildings would be very energy efficient as they would not be using a lot of AC.

They screwed up. 92F is NOT hot enough to cook an egg.

For an egg to cook and cars to melt, the temperature would have to be upwards of 160 degrees. Incidentally, 92C is roughly 200F.

100 degrees is 100 degrees. I think what you mean to say is concentrating the radiant energy from the sun that heats things up onto a small point, increasing its effectiveness at heating something up.

FWIW, this past summer at PHX when the temperature hit 118F, a local news station brought an infrared thermometer to the airport and recorded the ground at 160F.

Right, the intensity of the heat would be elevated versus it dispersing normally.

The story I saw on this also said it was 92° but added that this was °C. They were showing a digital thermometer that read 92 point something in big LCD letters held by someone in London. I wouldn't be surprised if some lazy American reporters didn't question the scale and reported it is °F. That temp would be unusually hot by Las Vegas standards, let alone London.

It was the same architect, Rafael Viñoly, who designed both buildings.

There was a snippit in this morning's Times that indicated that the aforementioned Mr Vinoly was aware of the heating problem, but the journo had the level of heating as "double what was expected". From the Guardian, below, the temperature "in the beam" was 72C instead of the expected 36C (really only about 10% higher in absolute terms. The joys of dumbed-down science)

http://www.theguardian.com/artanddes...tect-predicted-reflection-sun-rays



The architect of the Walkie Talkie building in London has admitted that he predicted it might reflect hot sun rays to the street below but "didn't realise it was going to be so hot".

Visiting London this week, Rafael Viñoly said the original design of the building had featured horizontal sun louvres on its south-facing facade , but these are believed to have been removed during cost-cutting as the project developed.
.
.
.
"When it was spotted on a second design iteration, we judged the temperature was going to be about 36 degrees," he said. "But it's turned out to be more like 72 degrees. They are calling it the 'death ray', because if you go there you might die. It is phenomenal, this thing."
