Foster + Partners Unveils Lusail Towers in

Qatar, a Landmark Project for a New Central 

Business District in the City

Written by Christele Harrouk

Foster + Partners has revealed its latest project for Qatar, a 1.1 million-square-meter landmark development consisting of four high-rise buildings. Part of a larger masterplan also designed by the architects, to be completed ahead of the 2022 Football World Cup in Qatar, Lusail Towers is envisioned as a “catalyst for a new central business district in the city”.

포스터+파트너스. 카타르  새 랜드마크 '루사일 타워' 공개

   세계 유수의 설계회사 포스터+파트너스는 4개의 고층 빌딩으로 구성된 110만 평방미터 규모의 랜드마크 개발 사업인 카타르를 위한 최신 프로젝트를 발표했다. 2022년 카타르 월드컵을 앞두고 건축가들이 설계한 대규모 마스터플랜의 일부인 루사일 타워스는 "도시의 새로운 중심 비즈니스 지구의 촉매제"로 구상되고 있다.

기후에 민감하고 새로운 교통 허브와 연결되는 새로운 도심 지역을 조성하는 포스터 + 파트너스는 카타르를 위한 4개의 고층 건물인 루사일 타워를 공개했다. 70층짜리 타워 두 개와 50층 높이의 타워 두 개를 중앙 광장에 대칭으로 배치한 이 프로젝트는 카타르 국립 은행, 카타르 중앙 은행, 카타르 투자국 본부를 카타르 디아르를 포함한 몇몇 다른 글로벌 기관과 함께 유치할 것이다.

새 축구 경기장과 협곡을 연결하는 대로의 끝에 위치한 이 개발은 도시를 위한 포스터 + 파트너 마스터 계획의 일부이다. 기후에 대응하여 설계되었으며, 기술 도구의 도움을 받은 통합 디자인은 "도시 규모에 따라 도시에 대응하는 동시에 인간 규모의 친밀한 가로경관"을 생성했다. 기지에는, 몇몇 단상 건물들이 각 탑을 둘러싸고 있으며, 공공의 영역을 움직이는 것을 돕는 가게, 카페, 그리고 식당들이 있다. 게다가, 해상 등급의 알루미늄 유리창으로 된 정면 차림은 밖과 낮의 경치를 보존하면서 거친 태양으로부터 내부 공간을 그늘지게 한다.

Creating a new downtown district that is sensitive to climate and linked to a new transportation hub, Foster + Partners unveiled Lusail Towers, a development of four high-rises for Qatar. The project that puts in place two towers at 70 stories, and two at 50-stories-high, arranged symmetrically around a central plaza, will host the headquarters for the Qatar National Bank, Qatar Central Bank, and Qatar Investment Authority alongside several other global organizations including Qatari Diar.

Located at the end of the grand boulevard that links the new football stadium to the corniche, the development is part of the Foster + Partners masterplan for the city. Designed in response to the climate, the integrated design assisted by technological tools generated an “intimate human-scale streetscape while responding to the city on an urban scale”. At the base, several podium buildings surround each tower, with shops, cafes, and restaurants that help animate the public realm. Moreover, the clad in marine-grade aluminum glazing of the facades shade the interior spaces from the harsh sun, while preserving views out and daylight.

The complexity of the project and the compressed timescales meant that the exchange of information between architects, engineers and other consultants needed to be almost instantaneous. From the outset, we established an innovative approach by creating a single platform that communicated design changes in real-time, enabling our integrated team work cohesively and at speed. -- Luke Fox, Head of Studio, Foster + Partners.

The team at Foster + Partners developed an in-house software system called ‘Hermes’ that coordinates design data for the project and facilitates the sharing of this data in real-time. On that note, Adam Davis, Partner in the Applied Research and Development team at Foster + Partners stated that “One of the most valuable contributions Hermes has made to our design process is to eliminate the need to manually rebuild models for different purposes. It allows us to work seamlessly across disciplines, facilitating prompt discussions between all the relevant individuals”.

The elliptical footprints of the towers morph through 90-degrees as they rise up, gently shifting the viewing axis outward and offering stunning views of the surrounding city and waterfront. The structure remains symmetrical in plan through this morph, and comprises a central concrete core surrounded by sixteen inclined columns around the perimeter, to create the unique geometry of the design. Wind tunnel tests were carried out early in the design process to inform the optimization of the structure. -- Roger Ridsdill Smith, Head of Structural Engineering at Foster + Partner.

“Environmental design was a key driver in the design”, states Piers Heath, Head of Environmental Engineering, Foster + Partners. In fact, he adds that “The morphing form was based on numerous studies and options with the aim of limiting solar exposure. The twisting shading fins were then developed to offer an optimal outer solar shade, along with an inherent reduction in exposed glazing. Targeting 4 stars in the regional Global Sustainability Assessment System (GSAS), the Lusail towers include active systems design including centralized thermal storage using innovative phase change materials, high-pressure hydronic systems, demand-controlled ventilation, efficient LED lighting, and advanced automation controls. In addition, molded concrete panels give the buildings a high thermal mass, with minimal punched windows that reduce the amount of solar heat to the interior spaces.
