Construction of Qatar’s ‘greenest’ office building completed

Construction of Qatar’s ‘greenest’ office building completed

After two years of construction, one of Qatar’s most environmentally-friendly office structures is finally open for business.

In a sign of the changing times, the QR120 million (US$32.95 million) redevelopment is not located in the downtown financial district, but in Bin Mahmoud.

There, an old cafeteria situated amid blocks of villas has been transformed into a new eye-catching office building.

The GATH building – named after its corporate owner, Ghanem Al-Thani Holdings – is located on Salwa Road, across from the Radisson Blu.

The office is part of a string of high-end developments along the road that also includes a nearly complete Westin hotel and apartments at Center Junction, near Megamart.

According to proponents of the building, the new office space is among Qatar’s greenest.

Though that title may soon be lost to one of the eco-friendly buildings under construction in Lusail, the GATH building contains several firsts for the country, including distinctive fan-shaped shades that run horizontally along the exterior of each floor.

Suspended by cables, the mesh shades are expected to reduce the building’s air conditioning requirements by 10 percent over a conventional office building, said Arab Engineering Bureau architect Martin Jakobson, who designed the building.

Inside, the ground floor is illuminated by an unobstructed skylight eight stories above it. In addition to the natural light, the hollow core of the building provides a “chimney” effect, Jakobson said.

Air rises up until it is trapped by the warmer air under the skylight, which contains the cooled air at the lower level. The cooled air in the office walkways will also flow down, lessening the cooling requirements on the lower levels.

The overall building design is loosely based on some of the more unusual coral found off Qatar’s coastline. Inside, the layout is intended to resemble traditional Arabic planning and architectural elements.

Visitors walk in to a central “courtyard” ringing by two stories of retail space. Above, a 25m-high plastic screen dotted with a randomized pattern of openings visually separates the private office areas from the semi-public courtyard below.

“We’re using traditional features in modern architecture,” said Jakobson, who firm also designed Al Sharq Hotel & Spa, the Kempinski Residences and the Barwa Al Sadd complex, among other projects.

So far, the only commercial tenant with a presence in the building is a luxury car dealer on the ground floor. But Jakobson said several of the two-story retail units were designed with cafes and restaurants in mind.
