“Heylo Düsseldorf” 原德勤总部大楼改造

在今天的建筑更新中，可持续性已变得至关重要。“Heylo杜塞尔多夫”改造项目——以前称为“Spherion”——多年来是德勤的总部。这座具有标志性的玻璃建筑建成于21世纪初，位于杜塞尔多夫-戈尔茨海姆的施瓦恩街，以其椭圆形的屋顶和彩色的外观元素而闻名。

When it comes to refurbishing existing buildings, sustainability is now a key consideration. The “heylo Düsseldorf” project - formerly known as “Spherion” – has been for many years Deloitte's headquarters. The identity-creating glass building on Schwannstrasse in Düsseldorf-Golzheim, with its elliptical roof and colourful façade elements, was completed in the 2000s.

HPP受业主委托对大楼进行全面翻新，包括建筑美学及能源效率等方面，所有工作预计将在2024年完成。届时，大楼将供不同租户使用，提供最先进的办公空间，并配备餐饮、运动设施及幼儿看护服务。新中庭将成为建筑的心脏，作为一个开放的绿洲贯穿所有楼层，提供各种休闲和交流区域。中庭一层将结合绿化景观设置非正式的交流及休闲区。上层则将设置双层高的公共空间，旨在根据新工作原则为多租户提供更为灵活的工作方式，从而重新活化整个中庭空间。

HPP was commissioned by the client to start a general renovation of the building both aesthetically and in terms of energy efficiency. The refurbishment is expected to be completed in 2024 and the building will be used as a multi-tenant property, offering tenants not only state-of-the-art office space, but also catering facilities, sports areas and childcare. The new atrium will become the heart of the building, extending through all floors as a green oasis and open space, offering a variety of recreational and communication zones. The ground floor will be featured with greened recreation areas with informal and communicative meeting spots. On the upper floors, double-height hubs and open spaces will be created to enable flexible working according to the New Work principle for multiple tenants, reactivating the entire public space.

HPP的设计团队与业主一起合作，把提升用户体验作为“heylo”改造项目的核心。通过融合多种数字化措施，将其打造成为一座智能建筑，例如，通过传感器优化自然光照和通风的能效控制。此外，外立面将结合如太阳能模块等进行创新性改造，为整栋建筑塑造一个具有前瞻性的新形象。建成后，heylo将达到碳中和的最高标准，并获得DGNB金牌认证。

Together with the client, HPP’s design team has put the user experience in the focus of the refurbishment. By integrating a variety of digitalization measures, they are transforming it into a smart building. For example, the light and air supply will be controlled in an energy-efficient way by sensors. In addition, creative interventions such as photovoltaic panels will be applied on the façades to create a new forward-looking image for the entire building. After completion, heylo will meet the highest requirements for CO2 neutrality. The aim is to achieve DGNB Gold certification.
