IZD Tower

IZD Tower is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IZD Tower rather than just read about it. In short: The IZD Tower (German: IZD Turm) is a high-rise office building in the Donau City district of Vienna, Austria. Built between 1998 ad 2001, the tower stands at 140 m (460 ft) tall with 37 floors and is the current third tallest building in Austria.

Key takeaways

IZD Tower belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IZD Tower to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IZD Tower from memory before moving on to harder problems.

Reference excerpt

The IZD Tower (German: IZD Turm) is a high-rise office building in the Donau City district of Vienna, Austria. Built between 1998 ad 2001, the tower stands at 140 m (460 ft) tall with 37 floors and is the current third tallest building in Austria.

History

Architecture The design and building permit for the 150 meter high building were provided by the architectural partnership NFOG (Nigst, Fonatti, Ostertag, Gaisrucker). Architect Thomas Feiger was responsible for the overall planning and construction management. Construction began in 1998 and the building was completed around three years later. It is used by rental offices; tenants of the IZD Tower include Ernst & Young, Huawei, Estée Lauder Cosmetics GmbH, easyJet Europe Airline GmbH and Austrian Power Grid AG . The total rental space on 42 floors is 63,530 m2. The highest floor is 130 m above ground level; the roof height is 137 m. The IZD Tower is one of the tallest buildings in Vienna. In 2006, the British real estate fund Matrix Securities acquired the building from the investment firm Doughty Hanson & Co for 244 million euros. In 2010, Signa took over the skyscraper. The US representation to the United Nations is located on the top floor of the IZD Tower. In the wake of the surveillance and espionage scandal in 2013, suspicions arose that a National Security Agency (NSA) listening post was located there, which could observe the UNO City, which is only 40 meters away. In September 2014, photos were leaked to the press showing special structures on the roof of the tower. The IZD Tower Staircase Run has been held every year in September since 2005. Depending on the accessibility of the top floors, participants run up to the 34th or 35th floor, which corresponds to around 630 steps. The current record time (2014) is 3:07.20 minutes.

Worked examples

Example 1 — a first encounter with IZD Tower

Start with the simplest possible case. Write down what IZD Tower claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IZD Tower before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IZD Tower ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IZD Tower

In research: IZD Tower appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IZD Tower in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IZD Tower is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2001 establishments in Austria, 21st-century architecture in Austria, Buildings and structures completed in 2001, so understanding it makes those chapters shorter.
In everyday life: Look for IZD Tower outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is IZD Tower in simple terms?

Why does IZD Tower matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study IZD Tower?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
