Tour Hekla

Tour Hekla 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 Tour Hekla rather than just read about it. In short: Tour Hekla is an office skyscraper in the La Défense district of Greater Paris. Built between 2018 and 2022, the tower stands at 220 m (720 ft) tall with 48 floors and is the current third tallest building in France.

Key takeaways

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

Reference excerpt

Tour Hekla is an office skyscraper in the La Défense district of Greater Paris. Built between 2018 and 2022, the tower stands at 220 m (720 ft) tall with 48 floors and is the current third tallest building in France. Named after the Icelandic volcano Hekla, the building is located in the Rose de Cherbourg area. It was designed by French architect Jean Nouvel.

History The building received its building permit in June 2016. Construction began in May 2018. Since completion in December 2022 it is the second-tallest building in France, only surpassed in height by Tour First, the tallest tower in the La Défense district. It's the third tallest structure in Paris under the Eiffel Tower. On April 13, 2012, an exclusivity agreement for the realization of the project was signed between Epadesa and the Hines/AG Real Estate/Gecina group. The Hekla Tower received its building permit in June 2016. On December 13, 2017, the Hines and AG Real Estate groups, which have developed the project so far, have signed the sale of the Hekla tower in its future state of completion (VEFA) to Amundi Immobilier and Primonial REIM, which plans for work to begin in June 2018. In April 2018, the public development establishment for La Défense announced the groundbreaking of the site for April 30, with the start of the foundation work for the tower on August 2018. After more than a year of work, the symbolic ceremony of laying the first stone took place on June 17, 2019, in the presence of the architect Jean Nouvel. The inauguration of the tower took place on December 1, 2022.

Architecture The project involves the complete rehabilitation of the Rose de Cherbourg sector, currently dominated by a motorway interchange, which will be pedestrianised and overlooked by a group of buildings including the Hekla tower. In addition to the Hekla tower, it will include nearly 35,000 m2 (380,000 sq ft) of housing, including 10,500 m2 (113,000 sq ft) of student accommodation. Led by the real estate groups AG Real Estate and Hines, the tower overlooks the N13 at the level of the Rose of Cherbourg in Puteaux. It occupies a total of 8,000 m2 (86,000 sq ft) of ground area, providing more than 76,000 m2 (820,000 sq ft) of offices on 48 floors, including five restaurants and a 250-seat auditorium, on a total of 51 levels. It is able to accommodate 5,800 employees on floors of 1,700 m2 (18,000 sq ft) and 3 meters of ceiling height. Due to its location on the Butte de Chantecoq, it will dominate the skyline of the business district, by 252 meters in relation to the Seine quays of the Esplanade de la Défense compared to 231 meters for the First tower, currently the tallest tower in the district. Of significant environmental quality, the tower has obtained 6 environmental labels, including HQE exceptional and Breeam Excellent. The cost of the project is estimated to be 248 million euros.

Worked examples

Example 1 — a first encounter with Tour Hekla

Start with the simplest possible case. Write down what Tour Hekla 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 Tour Hekla 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 Tour Hekla 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 Tour Hekla

In research: Tour Hekla 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 Tour Hekla 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: Tour Hekla is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2022 establishments in France, 21st-century architecture in France, Buildings and structures completed in 2022, so understanding it makes those chapters shorter.
In everyday life: Look for Tour Hekla 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.
