About D525 Barcelona オフィスビル

D525バルセロナは、1970年代に建てられた既存建築物をサステナブルに改修して生まれたオフィスビルです。延床面積7,000平方メートル、10層にわたるオフィスとネットワーキングエリアを備えています。メインファサードは、大きな窓と、空気を浄化する光触媒Krion製の立体モジュールを組み合わせています。南側ファサードに設けた太陽光発電ルーバーは、暑い時期に日射を遮りながらクリーンエネルギーを生み出します。低灌水の在来種を植栽した屋上庭園は、断熱性能を高めるとともに、周辺の微気候を改善します。

Unique Properties
The building of the new headquarters of Naturgy group in Barcelona, a building owned by Inmobiliaria Colonial, has been designed through the concept of sustainable renovation, recovering a building built with the aim of reducing its environmental impact of use, extending its efficient useful life. Its execution has been carried out with materials of strict respect for the environment and a comprehensive environmental quality management plan, and it has incorporated all construction requirements to achieve LEED Gold certification.
Dimensions & Packaging
D525 Barcelona is a Project of 7,000 square meters with 10 levels of offices and networking areas. All levels have a view of the roof garden located in level 1, which occupy a large part of the building. It was designed as a natural green space, incorporating low-consumption native plant species, which, in addition to providing an extra insulation layer, helps to minimize the environmental impact improving the microclimate and helping to mitigate the heat island effect.

Production Technology
The project integrates a main facade based on large windows that provide natural light, defined by unique photocatalytic krion 3D modules, which have the ability to purify the air thanks to their photocatalytic material.
The design of the south facade integrates a treatment of photovoltaic louvers, that protect from the sun in the warmer months of the year and generate enough clean energy to power 1562 points of light running 4 hours a day for 35 years and avoid the emission of 196 tons of CO2.
Design Challenge
The original building, from the '70s, was used for housing in the past and had several structural challenges. It had insufficient, altered pre-existing structure, with minimum floor heights and important deformations on the slabs that led to unevenness in a single floor of the order of 8cm. The current regulatory requirements called for creating new slabs openings for evacuation stairs and facility lines, making it necessary to replace the original stabilization core.
Research
The project has been developed using the latest BIM technology in the cloud for its complete coordination, integrating virtual models of architecture, engineering and interior design, in addition to the urban environment, generating a coordinated digital building.
Inspiration
The inspiration for this project was the concept of recovering an existing building to reform it and reduce its impact, providing greater sustainability and leaving a better tomorrow. The smooth and flowing forms of nature inspired the design of the building, breaking the traditional form of rigid vertical and horizontal lines, so that the building can be perceived as a pure and iconic element.
Project Duration
The project started in January 2020 and was completed in March 2021. It is located in Diagonal 525, Barcelona, Spain.
Operation Flow
Naturgy's new headquarters symbolizes the transformation of his company, with new, more sustainable, flexible and collaborative work environments, and it houses the corporate services that the company has.

The distribution of the workstations implemented in the building has been carried out according to the open space modality, with flexible, open and connected environments, and with a technology that allows total mobility of the employee. In addition, the new spaces are paperless, in line with the sustainability that the company is implementing in all its business lines.
