Appreciation towards BIG for providing the following description:

在第26届联合国⽓候变化⼤会（COP26）上，各国决⼼携⼿推进⽓候⾏动，⽽⾯对极端天⽓和⽓候变化对地球的影响，建筑师们也在积极地采取创新的解决⽅案。其中，最有效的可持续性绿⾊⽅式就是减少新建筑，即适⽤性再利⽤（Adaptive Reuse），由BIG担当设计的HB制铁总部⼤楼便是其中⼀例。通过创意整合来翻新结构，避免拆除现有建筑，从⽽节约能耗。

HB 制铁总部新的⾏政⼤楼包含了宜⼈的办公环境及令⼈印象深刻的展示厅。HB 制铁作为⼀家著名的钢材楼梯和阳台的制造商，最近开始涉⾜建筑的其他领域，提供⾼品质定制墙壁、地板和天花板的⽅案。业主把新的⾏政⼤楼构想为⼀个体现公司制造实⼒的地⽅，在这⾥展示钢材在结构，材质，及细节等⽅⾯的各种可能性。BIG与HB 制铁共同设计了⾏政⼤楼，业主同时也是主承建商。控制建设成本及碳排放是项⽬设计的⼀个关键因素，因此，新的⾏政⼤楼重新整合了三座现有建筑，并利⽤了裸露的结构和原材料的表⾯。建筑的外部，由⻛化的全⾼考顿耐候钢板覆盖两侧，与其红⾊砖墙相融合，另外的两侧则由简洁的玻璃⽴⾯构成。

The design brief for HB Trapper & Stål’s HQ was to combine a serene office environment with the excitement of a large, impressive showroom. While originally manufacturing primarily steel stairs and balconies, HB Trapper & Stål has expanded into other fields of the building process, including bespoke wall, floor, and ceiling solutions defined by high-quality finishes and detailing. With the facilities to manufacture and assemble most parts of the building already on-site, it was important that the new administration building exemplify both the manufacturing capabilities of the company, and the versatility of the steel material that underscores HB Trapper & Stål’s expertise. BIG worked directly with HB Trapper & Stål to co-design the building, with the client also being our main contractor. Minimizing construction costs – in addition to minimizing the carbon footprint of the renovation – was a key factor in the design of the project. As such, the new building is an adaptive reuse project that integrates parts of three existing buildings, celebrating exposed structures and raw material surfaces: the exterior north wall of the manufacturing building, the foundation and floor slab of the old administration building, and most of the original brick administration building, reducing the project’s material use. On the exterior, the building is clad in full-height, weathered Corten steel plates on two sides, blending the building in with the red brick manufacturing buildings, while a simple glass façade wraps the other two sides.

在建筑内部，⼀些新的体块与现有建筑物⼀起构成了⼀个⼩型功能村，为钢铁和玻璃构成的巨⼤的空间作了巧妙的划分，向访客展现各种不同类型的钢材及其令⼈惊叹的材质属性。值得⼀提的是，BIG近期公布的MARSK双螺旋瞭望塔的环状钢铁楼梯即由HB制铁提供。

On the interior of the building, several small new spaces, together with the reused existing buildings, make up a small village of functional areas. This subdivides the large space that is defined by the exterior steel and glass skin, providing visitors with a glimpse of the unique material properties of different types of steel.

该建筑将所有⼯作区都朝向北⽅，最⼤地利⽤漫射⽇光并极度减少太阳热量的吸收。屋顶将太阳能电池板与天窗相结合，为办公区域提供更多的漫射⽇光，并作为建筑物混合⾃然/机械通⻛系统的⼀部分，从⽽减少能源消耗并降低建筑物的运⾏成本。

The building orients all work areas towards the north, maximizing diffused daylight and minimizing solar heat gain. The roof integrates solar panels with a large skylight, providing further diffused daylight to the office areas and functioning as part of the building’s hybrid natural/mechanical ventilation system, resulting in low energy use and reducing running costs for the building.

由于业主同时也身为主承建商，建筑过程中最⼤限度地优化了建筑结构并减少了材料的消耗。在这样紧密的合作中，定制钢材能够在现场建模及测试，这包括⻔把，会议桌，厨房设施，天花板，⾦属栏杆，电源插座，通⻛⽹，及玻璃⽴⾯直棂。

With the client also being the main contractor, the construction process was able to maximize the efficiency of structures while minimizing material use. This close collaboration also allowed for bespoke steel designs that could be quickly mocked up and tested on site, including everything from door handles and meeting tables to kitchen elements, railings, electric outlets, ventilation grills, and glass façade mullions.
