The BBVA Tower demonstrates that it is possible to create sustainable architecture that goes hand in hand with design

( Spanish) — Since its inauguration in 2016, the BBVA Tower has become an icon of Mexico City. Not only is it a modern, sustainable and innovative building, it is also a space that promotes a sense of community and celebrates Mexican culture in its design.

Located on Paseo de la Reforma, the main avenue of the Mexican capital, this towering skyscraper marks the entrance to the Bosque de Chapultepec —a huge park covered in leafy trees— or, depending on where you look at it, it is also where the financial center begins. of the Mexican capital.

The 50-story project, with large terraces and raised gardens, was designed by the Mexican architect Víctor Legorreta and the British architect Richard Rogers, after they won a competition in 2010. From this came LegoRogers, the merger of the British firm Rogers, Stirk Harbor + Partners (RSHP) and the Mexican Legorreta + Legorreta.

A sustainable architecture that goes hand in hand with design

With the BBVA Tower, Legorreta and Rogers reinforce the existing possibility of building from an architecture that responds to the environment and is aesthetic at the same time.

They took advantage of the qualities of a wooded urban environment that surrounds the building and the climate of Mexico City to integrate a system that allows the natural circulation of air, without the need to use the air conditioning much of the year.

In addition, the building is fully illuminated with LED technology, which allows a more efficient use of light, and its wall-free interior design means that natural lighting occupies a central place, reducing consumption by 20%.

“Both Rogers and we are passionate about sustainability […] That’s where the idea of ​​making a double façade came from, in which there was a kind of filter, which would let you see from the inside out but would not allow the sun to pass through,” Legorreta says in an interview with en Español.

Not only is electricity used less in this skyscraper, it also has “treatment plants for the recirculation of water”, which translates into a consumption reduction by 80.5%.

These innovative solutions in environmental matters that the BBVA Tower has, earned it LEED Certification (Leadership in Energy and Environmental Design, for its acronym in English) Platinum, awarded by the US Green Building Council, a global movement that advocates for sustainable building.

In turn, the engineering used in the second façade is complemented by a design that evokes the particular geometric figures of pre-Hispanic culture and the vibrant colors that characterize Mexico.

“The use of color, of course, is very Mexican because I can’t imagine anywhere else in the world where you can make a tower with more than 50 levels with a purple façade… in London, Tokyo or New York it would have to be Gray”.

A building that reinterprets the work space

The idea of ​​this tower is a reinterpretation of the traditional organization of an office space. According to Legorreta, it was important for the BBVA bank that its headquarters in Mexico City be a space that promotes coexistence, giving it a sense of community.

“It has this happy part and this human part and that people can come with a different spirit to work, to see friends, to have more community and not just to fulfill a specific task.”

For this, they created dining rooms with access to triple-height gardens, inspired by the central patios of the classic constructions of the colonial era, which give variety to the building’s facilities.

It also has a heliport that “was an area that was going to be purely utilitarian and ended up being a phenomenal terrace to see the whole city,” says the Mexican architect.

Build a 235-meter building in a seismic zone

One of the great challenges that Legorreta and Rogers faced was to build a 235-meter-high building in one of the riskiest seismic zones in Mexico City.

“It’s quite a challenge because you’re still on the shore of what was Lake Texcoco. So, the ground is very bad, to begin with. We found the solid ground more than 52 meters deep.”

Legorreta explains that they had to create a project in which engineering and architecture went hand in hand.

“We had to build a foundation at more than 52 meters with piles and a whole wall around the building, which is called the Milan wall, to make it stable. Then we had to put a structure that also had flexibility but that would resist tremors,” he explains. .

Víctor Legorreta started this project with his father, the renowned Mexican architect Ricardo Legorreta, who passed away at the end of 2011, a year after they won the competition with Richards to build the BBVA Tower and when they were just starting with the executive plans.

“Of course I would have loved for my dad to see it finished as well. I think he would be very proud of this project and in some way it is a tribute to him from a city where he lived all his life and that he loved very much.”
