The designbrief

设计概要

As a regionalbank, Caisse d’Epargne, a member of the BPCE group, shouldbe part of the French territorial reform adopted by President Hollande in2015.It had two regional headquarters : one in Besançon and one in Dijon, the latterbeing located in two adjacent but not adjoining buildings.

作为一家地区性银行，法国巴黎银行（Caisse d'Epargne）是BPCE集团的成员之一，理应成为奥朗德总统在2015年通过的法国领土改革的一部分。法国巴黎银行有两个地区总部:一个在贝桑鬆，另一个在第戎，后者位于两个相邻但不相邻的建筑物内。

It is in thiscontext, as part of its business project aimed at accelerating itstransformation, the Caisse d’Epargne BFC wanted a new head office inDijon which aims to be exemplary.Owner of forests in the Morvan, a low mountainmassif a few kilometers from Dijon, the Caisse d’Epargne wantedto be a new head office demonstrating local resources but not ostentatious forits members, testifying to its environmental commitment.

正是在这种情况下，作为其业务项目的一部分，旨在加快其转型，瑞士银行第一公司希望在第戎设立一个新的总部，旨在成为典范。位于距离第戎几公里的低山地带Morvan的森林拥有者，Caisse d'Epargne希望成为一个新的总部，展示当地的资源，但不为其成员炫耀，证明其对环境的承诺。

Concepts

概念

The main idea wasfor a wooden demonstrator building inscribed on a sloping ground. Like an openbook on the great landscape, the book of the history of wood construction inFrance. This square facing the large landscape that wants to show and explainin an educational way what wood construction is.

设计的主要想法是在倾斜的地面上建造一个木制的示范建筑。就像一本关于伟大风景的打开的书，法国木结构的历史之书。这个面向大景观的广场想要以教育的方式展示和解释什么是木结构。

The building isthen part of a structuralist reflection: show the structure, show the formaldissociation between structural elements, according to their role and theirstructural behavior: “dynamic” for the bracingexoskeleton, but “static” for the post­beamof the facades with timber frame filling.

建筑是结构主义反思的一部分：显示结构，显示结构元素之间的正式分离，根据它们的作用和它们的结构行为：“动态”用于支撑外骨骼，但“静态”用于木框架填充的立面顶梁柱。

The client wasfirst convinced by the use of local forest wood as part of their investment,this point particularly responded to their local economic roots. They were alsohit by the form : a two level base, stable and anchored to its land, and a 4level upper part. Fun fact, this form was for them the expression of a bank “seat” which is theFrench translation of a headquarters.

客户首先被说服使用当地森林木材作为其投资的一部分，这一点特别回应了他们当地的经济根源。他们也被形态击中：一个两层的基地，稳定和锚定到它的土地，和一个4层的上部。有趣的是，这种形式对他们来说是一个银行“席位”的表达，这是一个总部的法语翻译。

Location andposition of the building

建筑物的位置

Located in ZACValmy , a new business district in the northern outskirts of Dijon, theheadquarters of the Caisse d’épargne of Bourgogne Franche-Comté is served by a circular boulevard (RN 274)and line 2 of tramway, “Pôle Santé” station. Theplot’s eastern and western slopes (8300 m2)welcome parking for visitors. Employees park their vehicles in the concretebase as well as in the parking silo built in wooden structure, at the site’s north. Not only does the natural slope ofthe ground allow a

single storeyaccess to the base’s parking, but it also installs a slightlyoverhanging ground floor level, so that users benefit from a clear view on theenvironment.

位于第戎北部郊区的新商业区ZAC Valmy,Bourgogne Franche-Comté银行的总部由一条环形大道（RN 274）和有轨电车2号线"Ple Santé"站提供服务。地块的东部和西部斜坡（8300平方米）欢迎游客停车。员工将他们的车辆停放在混凝土基座中，以及在场地北面的木製结构的停车筒仓中。地面的自然坡度不仅允许单层访问基地的停车场，但它也安装了一个稍微悬垂的地面层，使用户受益于一个清晰的环境视图。

Outline detailsof local vernacular building

勾勒当地乡土建筑的细节

The design of thisbuilding, draped in its exo wooden structure, echoes the half-timbered housesof the historic center of Dijon. The half-timbering is the set of beams formingthe framework of a wall, this wooden frame is made up of wooden sections whosebeams delimit the filling compartments. In the history of French construction,half-timbered houses have been present for many centuries. This constructivemethod of small wooden elements highlights the use of local resources,available in reasonable quantities.

这座建筑的设计采用外木结构，与第戎历史中心的半木结构房屋相呼应。半木结构是一组樑构成了一堵墙的框架，这个木框架是由木段组成的，木段的樑界定了填充隔间。在法国建筑史上，半木结构房屋已经存在了许多世纪。这种小木构件的建设性方法突出了当地资源的使用，可在合理的数量。

It was with theFirst World War, the loss of many carpenters and their know-how in the trenchesas well as the arrival of reinforced concrete that stopped the evolution ofthis construction method.

直到第一次世界大战，许多木匠和他们在战壕里的技能的损失，以及钢筋混凝土的到来，才停止了这种建筑方法的发展。

This large-scalebuilding wishes to highlight the pursuit of French know-how of traditionalcarpentry and the reasoned use of materials.

这座大型建筑希望强调对法国传统木工技术的追求和合理的材料使用。

Ground floor :

a crossingNorth-South axis

一楼:

横贯南北的轴线

The main entranceis located on Françoise Giroud avenue, facing the tramway, where the architectsdesigned a large covered parvis (ground made with Bourgogne stones), lengthenedby a succession of interior and exterior crossing spaces: patio, lobby, atrium,secondary entrance hall, from which one joins the parking silo. Fully glazed,this spatial structure of the ground floor’s central part generates two wingswith distinct functions. The first one, at the east, shelters the sports halland rooms for logistics (mail treatment for instance). The second one, at thewest, presents a public vocation, with training and reception rooms.

主入口位于Francoise Giroud大道，面对有轨电车，建筑师在那里设计了一个大的带顶棚的走廊（地面由勃艮第石头制成），由一系列的内部和外部交叉空间延伸：天井，大堂，中庭，二次入口大厅，从那里一个连接到停车筒仓。全玻璃，这个空间结构的一楼的中央部分产生了两个具有不同功能的翅膀。第一个，在东部，庇护体育馆和后勤室（例如邮件处理）。第二个，在西部，是一个公共的职业，有培训和接待室。

1級至6級：第一天點亮

在每一個工作站

Every office(mainly 300 m2 platters) and meeting rooms (placed between the atrium and thepatio) benefit from a natural direct lightening. Refuting tertiary real estatestandards, its doubling of corridors and its built thickness between 18 and 21meters, GRAAM devoted themselves to diversify user’s experience of the Caisse d’épargne,and their relation to exterior.

每个办公室（主要是300平方米的大盘子）和会议室（位于中庭和天井之间）都受益于自然的直接照明。GRAAM打破了三级房地产的标准，其走廊的两倍和18至21米之间的建筑厚度，致力于使Caisse d'épa rgne的用户体验及其与外部的关系多样化。

COMPLEMENTARYLEVELS

互补的水平

The last fourlevels’ thickness, comparable to the one of housing buildings, is only 13.5meters. This modest dimension in terms of rentability is compensated by theimportant superficy of the first two levels (40.50 x 62 m), whose center islightened by the atrium as well as by the patio. Goal: create an interiorisedenvironment, complementary to the extrovert universes of peripheral spaces andsuperior levels, which offer aerial panoramas on Dijon and its countrysides.

后四层的厚度仅为13.5米，与住宅建筑的厚度相当。在可出租性方面，这个适度的尺寸被前两层的重要表面(40.50 x 62米)所补偿，其中心被中庭和天井照亮。目标是创造一个内化的环境，与周边空间和上层空间的外向宇宙互补，提供第戎及其乡村的空中全景。

The subtlecombination of wood,

concrete, steeland glass

木材的微妙组合，

混凝土，钢铁和玻璃

The building isset on a slope, facing a landscape where, in good weather, the peak of MontBlanc rises in the distance. Its glazed skin, placed lightly on the timberexostructure, allows the wooden mesh to appear or to reflect the greatlandscape, making the building disappear, depending on the weather. The formaldissociation of the structural elements, according to their role and behaviorallowed the realization of a bioclimatic ventilated double skin. Made of simpleextra-clear glass, the external wall of the latter is suspended from the upperbeams of the wooden exoskeleton. The combination of concrete, timber, steel andglass makes this building unique.
这座建筑坐落在一个斜坡上，面对着一片风景，在天气好的时候，勃朗峰的顶峰在远处升起。它的釉脸皮肤，轻轻地放在木材外部结构，允许木製网格出现或反映伟大的景观，使建筑消失，这取决于天气。根据其作用和行为，结构元素的正式分离允许实现一个生物气候通风的双层皮肤。后者的外墙由简单的超透明玻璃製成，悬挂在木质外骨骼的上部横梁上。混凝土、木材、钢材和玻璃的组合使这座建筑独具特色。

A building withthe least possible impact

一栋影响最小的建筑

The forceful ideaof GRAAM: investing on the territory and projecting into the future ! In otherwords : realizing a demonstrative building on wooden structure, by local firms,recalling that the Bourgogne Franche-Comté region has wide forests, which hasthe least possible impact on its environment.

GRAAM强有力的理念：投资于地区，展望未来！换句话说：由当地公司在木结构上实现一个示范性建筑，考虑到勃艮第弗朗什孔泰地区拥有广阔的森林，这对环境的影响最小。

The building isbuilt 100% dry process (and offsite) and has 2579 m3 of wood, that is 2579 T ofstored CO2. Built to a high thermal standard (passive building), it consumesonly 15 kW/h per m² annually. The implementation of the smart buildingcertification (R2S) allows an open and communicating building.

该建筑采用100%干法（和场外）建造，并拥有2579立方米的木材，即2579吨储存的二氧化碳。它采用高热量标准（被动式建筑），每年每平方米耗电量仅为15 kW/h。智能建筑认证（R2S）的实施使得一个开放和通信的建筑成为可能。

TAKING CARE OFTHE RESOURCE

Cross laminatedtimber with moderation

爱护资源

适度的交叉层压木材

Generalizing theuse of CLT to build a wooden building is debatable. This process, native fromAustria where resiniferous trees are abundant and renewable in only a fewdecades, poorly harmonizes with the French constructive tradition, consumingless materials, for correlated to a wooded patrimony essentially composed byhardwood which growth is much slower (about 80 years).

推广使用CLT来建造木质建筑是有争议的。这一过程原产于奥地利，那里有大量的树脂树，只需几十年就可再生，与法国的建筑传统不太协调，消耗较少的材料，因为与由硬木组成的木质遗产相关，其生长速度要慢得多(约80年)。

Materialoptimization

材料优化

Faithful to theirrequirement in matters of material optimization ( the right material in theright place), GRAAM has drawn a supporting structure made of glulam posts (arow on the facade, and a double row in the central circulation), on which standLVL longitudinal beams in and glulam transversal beams. Cross Laminated Timberis only used in two cases, when they are strictly necessary for bracing : corewalls and center circulation floors , in which transit wind loads aretransmitted by the triangled exoskeleton.

为了忠实于他们在材料优化方面的要求（在正确的地方使用正确的材料），GRAAM设计了一个由胶合木柱子组成的支撑结构（立面上的一排，中央循环中的一排），在其上放置LVL纵梁和胶合木横梁。交叉层压木材仅在两种情况下使用，当它们是严格必要的支撑：核心墙和中央循环地板，其中过境风荷载传递的三角形外骨骼。

A green energybuilding

绿色能源建筑

Wood, a livingmaterial, allows a natural regulation of the ambient hygrometry. The materialsused in the office spaces, all classified A+ in terms of VOC emissions,combined with a ventilation system that allows for air renewal above the norm,ensures high indoor air quality. Cooling is achieved by an adiabatic system ofcooling the water network passing through the technical ceilings. The buildingis connected to district heating: a city network heated by biomass, 100%renewable energy.

Heating andcooling is made by radiation from the ceiling.

木材是一种活的材料，可以自然调节环境湿度。办公空间所使用的材料，在VOC排放方面都被归类为A+，加上通风系统，允许空气更新高于标准，确保了高室内空气质量。冷却是通过一个通过技术天花板冷却水网络的绝热系统实现的。该建筑连接到区域供热：一个由生物质供热的城市网络，100%可再生能源。加热和冷却是由天花板的辐射产生的。

Safety andsecurity of occupants

居住者的安全和保障

The building isdivided into 300 m² platforms intersected by fireproof walls for 1 hour. Thethree vertical circulations are also partitioned, fireproof for 1 hour andtheir interior lining is incombustible.

该建筑被划分为300平方米的平台，由防火墙相交1小时。三个垂直循环也被划分，防火1小时，其内衬是不燃的。

Dry risers locatedin the staircase may be used, provided that they open less than 40 m from afire hydrant.On the largest facade (North West facade) each level is accessibleby a firefighter access materialized on the facade by a red dot.

可以使用位于楼梯上的干立管，但其开口距离消防栓不超过40米。在最大的立面（西北立面）上，每一层都有消防员进入，在立面上用红点体现出来。

The bioclimaticdouble skin is cut against fire every two levels, and the large ventilationgrids allow the smoke, if necessary, to evacuate quickly.

生物气候的双层表皮每隔两层就被切割成防火层，如果有必要，大型通风网格可以让烟雾迅速排出。

The building isdivided into 300 m² platforms intersected by fireproof walls for 1 hour. Thethree vertical circulations are also partitioned, fireproof for 1 hour andtheir interior lining is incombustible.

该建筑被划分为300平方米的平台，由防火墙相交1小时。三个垂直循环也被划分，防火1小时，其内衬是不燃的。

Dry risers locatedin the staircase may be used, provided that they open less than 40 m from afire hydrant.On the largest facade (North West facade) each level is accessibleby a firefighter access materialized on the facade by a red dot.

可以使用位于楼梯上的干立管，但其开口距离消防栓不超过40米。在最大的立面（西北立面）上，每一层都有消防员进入，在立面上用红点体现出来。

The bioclimaticdouble skin is cut against fire every two levels, and the large ventilationgrids allow the smoke, if necessary, to evacuate quickly.

生物气候的双层表皮每隔两层就被切割成防火层，如果有必要，大型通风网格可以让烟雾迅速排出。
