UNStudio最近中标Hanwha首尔总部办公楼重建项目。随着对总体景观的重新设计，重建对办公大楼的外观、内部公共空间、大厅、会议层、礼堂和办公区都进行了重整。坐落于首尔清溪川，面积为57696平方米的Hanwha总部大楼曾一度被认为不能再反映其作为世界上领先环境技术提供商的地位象征。为此Hanwha公司拉开总部办公大楼重建比赛，UNStudio与Arup( 可持续性与幕墙顾问)以及Loos van Vliet(景观设计师)和agLicht（大楼内部、景观和外墙照明的照明顾问）联手，最终赢得比赛。
Ben van Berkel / UNStudio’s design selected as winning entry for the remodelling of the Hanwha Headquarter office tower in Seoul.
UNStudio’s design has been selected as the winning entry in the competition for the remodelling of the Hanwha headquarters building in Seoul. The renovation of the office tower incorporates the remodelling of the facade,the interior of the common spaces, lobbies, meeting levels, auditorium and executive areas, along with the redesign of the landscaping.
Located on the Cheonggyecheon in Seoul, the 57,696 m2 headquarter building was seen to no longer reflect Hanwha as one of the leading environmental technology providers in the world. For the competition to remodel the tower UNStudio teamed with Arup (sustainability and facade consultant) and Loos van Vliet (landscape designer). Following the selection of the competition design, agLicht joined as lighting consultant for the interior, landscape and facade lighting.
外墙由一个个LED像素灯组成，能形成可回应街道活动的动态图景。不同的灯光可反映 不同的区域，突出有活动的部分。外观像素化照明运用了数据处理和节能理念，旨在形成Hanwha新的品牌形象，有助于巩固其作为世界领先环保技术供应商的地位。Ben van Berkel提到：“Hanwha总部大楼外表皮设计避免了浮夸。夜晚，外墙的灯光变得仿佛星空一样，与天空融为一一体，建筑的庞大体量也不再明显。”
The concept for the animated facade lighting responds to the media activities on Hanbit Avenue. The facade is animated by individual LED pixels, with the lighting reflecting different parts of the building and highlighting areas
of activity within. The pixelated lighting references nature, data processing and energy forms and is designed to
form part of the overall Hanwha branding strategy with its position as one of the world’s leading environmental
technology providers.Ben van Berkel: “The design for the Hanwha HQ media facade aims to avoid an overstated impact. In the evenings, as the mass of the building becomes less apparent, the facade lighting integrates with the night sky, displaying gently shifting constellations of light.”
设计与环境和自然息息相关，为此UNStudio开发了一个响应式外墙系统，其根据反应程序改善了建筑室内气候。Ben van Berkel说：“通过集成式的外立面设计，Hanwha总部大楼的内部气候被显著改善，提高了使用者的舒适度并具有高水平的可持续性和承受力。这种集成的设计策略对外界环境反应迅速，能适时改善内部条件。
Responsive facade concept
In response to the request that the design be guided by the surroundings, influenced by nature and driven by the environment, UNStudio developed an integrated responsive facade concept which improves the indoor climate of the existing building and reacts to both the programme distribution and the location.Ben van Berkel: “By means of a reductive, integrated gesture, the facade design for the Hanwha HQ implements fully inclusive systems which significantly impact the interior climate of the building, improve user comfort and ensure high levels of sustainability and affordability. Through fully integrated design strategies today’s facades can provide responsive and performative envelopes that both contextually and conceptually react to their local surroundings, whilst simultaneously determining interior conditions.”
Social well-being is considered fundamental for enhanced creativity and concentration and is driven by several
factors, the most significant of which is the improvement of the indoor environment – primarily in order to enhance physical comfort. The existing façade contains horizontal bands of opaque panelling and single layers of dark glass. In the remodelling this will be replaced by clear insulated glass and aluminium framing to accentuate views and daylight. The geometry (pattern, size and reveal) of the framing is further defined by the sun andorientation factors to ensure user comfort inside and reduced energy consumption.In the design for the Hanwha headquarter building the North facade opens to enable day lighting within the building but becomes more opaque on the South façade, where the sun would otherwise have too much impact on the heat load of the building. Openings within the facade are further related to the views: opening up where views are possible but becoming more compact on the side adjacent to the nearby buildings.
Solar impact and PV integration
Direct solar impact on the building is reduced by shading which is provided by angling the glazing away from direct sunlight, while the upper portion of the South facade is angled to receive direct sunlight. The window to wall ratio is taken into account in order to achieve 55% transparency across the entire facade, while PV cells are placed on the opaque panels on the South / Southeast facade at the open zones where there is an optimal amount of direct sunlight. Furthermore, PV panels are angled in the areas of the facade where energy from the sun can best be harvested.
The basis for the facade expression is to achieve an effect of variety, irregularity and intricacy throughout the facade. This is approached by combining a system of multi-scaled elements in a simple fashion and is additionally informed by the programme. By varying the placement of the facade panels a variety of programme-relatedopenings are created. Variations in programme therefore create the opportunity for differentiation, with theresult that the restaurant, the executive room, the sky gardens, the seminar spaces etc. are all expressed in the facade.
Interior concept – lobby
In UNStudio’s concept for the lobby of the Hanwha headquarter building the landscape continues into the interior
and acts as a guiding aid, while natural materials and planting provide a relaxing environment for visitors. A subtle
colour scheme is combined with wooden furnishing and in both the North and the South entrance lobbies a coffee
corner creates the possibility for social interaction and exchange.
