Tallest Building in America?


Tallest Building in America?

One World Trade Center Just Might Be!

One World Trade Center has been crowned the tallest building in the Americas, standing at a symbolic (and now official) 1,776 feet. The Council on Tall Buildings and Urban Habitat, an international body that determines the heights of skyscrapers, has ruled that the spire atop One World Trade is an architecturally significant feature of the building — not an antenna. Council chairman Timothy Johnson said that the spire was clearly “the end of the architectural expression of the building,” adding at a press conference today that “for us it was very clear that it was a spire and not an antenna.” Johnson is also a partner at NBBJ, a global architecture firm.

The decision makes the official height of the building 1,776 feet, not 1,368 feet, which is the height of the building’s roof. It also allows One World Trade to beat out Chicago’s Willis Tower as the tallest in the US. Willis Tower’s antenna does not count towards its official “architectural height.” Internationally, the Council is now projecting that One World Trade will be the third tallest building in the world upon completion, behind the 2,717-foot Burj Khalifa and the 1,972-foot Makkah Royal Clock Tower Hotel in Mecca.

One World Trade Center’s spire doesn’t include any radio or broadcast equipment — it only features decorative lighting — and that fact seems to have helped it win the Council’s favor. Johnson explained that “having been on the roof of the World Trade, this is essentially a small building up there,” referring to the spire. He added that a small lightning rod and a light above the spire that serves to warn airplanes do not count towards the height, and the 1,776-foot measurement does not include those minor functional pieces of equipment.

The 25-person Council, comprised of architects, engineers, contractors, academics, and suppliers, met on November 8th in Chicago to make a decision, and as it typically does, the council re-evaluated its criteria before making a ruling. The team concluded that the rules were valid, and then made the unanimous decision to rule that the spire was not an antenna. As for the actual measurement 1,776 feet, the Council relies on One World Trade’s architectural plans. This means that the team is “basically taking the word of the architects and engineers,” as Johnson explained, noting that the procedure is the same for all other skyscrapers.

There are three different height criteria used by the Council on Tall Buildings and Urban Habitat: “height to the architectural top,” “highest occupied floor,” and “height to tip.” The Willis Tower beats out One World Trade for the highest occupied floor, at 1,354 feet vs. 1,268 feet. Only the architectural height is used to determine the tallest buildings in the world, however, and it’s also the most controversial. This measurement officially includes spires, but not “antennae, signage, flag poles or other functional-technical equipment.”


Not only does One World Trade’s spire not include functional equipment, it also is perceived as a permanent fixture on the building. Antennas like that found on Willis Tower have been swapped out and removed in the past. Indeed, the Willis Tower — called the Sears Tower at the time — had its two antennas added in the early ’80s, close to ten years after the building’s completion. In 2000 one of the antennas was replaced with a taller antenna for improved reception. The spire on One World Trade, in contrast, is made of stainless steel and is integrated into the building’s design, according to the Council. Should it ever be replaced or repurposed as an antenna, the Council would revisit its decision, according to Johnson.

The decision was clearly fraught with political interest, and some may point to those forces as influencing the decision today. Johnson said in light of the pressure that “we were very happy that our conclusion was that we were able to ratify that that was the height of the building.”

Does Germany have enough sun for their solar technology?

Does Germany have enough sun for their solar technology?

Article from Zachary Shahan, Cleantechnica.com

Germany Breaks Monthly Solar Generation Record, ~6.5 Times More Than US Best

I live in Poland, which (for the geographically indifferent) is right next to Germany. Actually, the city where I live, Wroc?aw, was once part of Germany, and it’s now just a couple hours to the German border from here. From living in this city for 5 years, I can tell you one thing with great emphasis: this is one super-grey area of the world. Actually, the weather at the moment reminds me of winter weather in Florida (my home state). I was looking at a lot of solar irradiation maps and stats just yesterday, and I happened to notice that Florida gets about twice as much average sunshine per day as Wroc?aw — I’m sure it’s the same across Germany. So, really, I am stunned when I think about how much solar power the country is producing relative to other countries (especially relative to the humungous and sunny USA).

Germany solar power recordIt was just reported the other day that Germany has broken its monthly solar power generation record yet again. (This follows a couple of record-breaking days in terms of solar output, news about the first of which was broken by CleanTechnica, and the second of which is noted in the chart on the right.) In July, the super-grey country rose above 5.1 TWh of electricity from solar panel systems. That’s according to the latest data from the EEX Transparency Platform.

That actually beats the 5 TWh of electricity from wind turbines that the country logged in January (it’s also a wind power leader, in case you weren’t aware).

More emphatically, that crushes the 0.764 TWh of electricity solar PV and solar thermal systems produced in the US in May 2013 (the latest month for which we have data) as well as the 0.522 TWh produced in the US in July 2012.

If we assume the US got the same amount of sunshine in July 2013 as in July 2012, and that solar power capacity grew by the same proportion between May 2013 and July 2013 as between May 2012 and July 2012, the US net generation total for solar PV and solar thermal in July 2013 should equal about 0.780 TWh. In other words, despite having a ton more sun(see the maps below) and being larger geographically than all of Europe, the US generated about 6.5 times less electricity from solar power than Germany did in July. Stunning. Depressing. Motivating….

In terms of total solar power capacity per capita, Germany crushes every other country. At the end of 2012, it had approximately 400 MW of solar power capacity per million people, considerably more than #2 Italy at 267 MW per million people, #3 Belgium at 254 MW per million people, #4 Czech Republic at 204 MW per million, and #5 Greece at 143 MW per million people. The US came it at #20 with about 25 MW per million people (quite pitiful when put into this perspective). The top solar state (per capita) in the US at the end of 2012 was Arizona, which had about 167 MW of solar power per capita (and would have ranked #5 if it were a country).

Getting back to Germany’s new solar power record, sunny weather and increased solar power capacity raised the country’s July 2013 output about 42% over its July 2012 output.

Another wonderful thing to note about Germany’s massive solar power capacity is that it’smostly on the roofs of homes and businesses. Furthermore, the massive increase in solar panel installations in the country has brought down the price of solar considerably, making it nearly half as much as in the US, despite higher labor costs.
