源于地块特点的独特设计
Unique design born from the site’s characteristics

本项目是位于目黑站和五反田站之间铁路沿线中间位置上的开发街区“MEGURO MARC”内的租赁式办公楼，该地区是东京都内最便利的商务区之一。地块被住宅区和郁郁葱葱的绿化环绕，自拥一方幽静沉稳。地块北面有铁路，南面有高差10m的目黑川河岸阶地，附近还有高层办公楼和住宅。

This tenant office building is situated within the MEGURO MARC development district, located halfway between Meguro Station and Gotanda Station along the railway line in a convenient business area in Tokyo. The site is surrounded by residential areas and abundant greenery in a calm environment. The area also features railways to the north, Meguro River’s riverside terrace 10 meters in depth to the south, and proximity to high-rise office buildings and residential buildings.

鳍状外装PC预制板不仅使建筑富有特色，还可避免与邻近的办公楼和住宅间产生视线干扰，将视线引导至视野开阔的方向。同时,还可起到遮挡日晒和减少光污染的作用，既能确保高质量的室内环境，又考虑到了周边环境。相对于来自周边的视线，倾斜的形状使建筑呈现出多变的外观，成为视觉上的亮点。从河岸阶地的下方抬头仰望，可以看到具有重量感的PC预制板墙面，在绿意盎然的阶地上形成庞大的体量和象征性的外观。此外，还通过在主入口处设置安装了调谐质量阻尼器（TMD，Tuned Mass Damper）的最大达7.5m的悬挑式铝合金蜂巢板大屋檐，形成牢固稳定的正立面。

The building’s distinctive fin-shaped exterior precast concrete (PC) panels serve to avoid direct sightlines with neighboring offices and residences and guide views towards more open directions. These panels also function as sunshades and reduce light pollution, ensuring a high-quality indoor environment while considering the surrounding environment. The diagonal shape of the panels changes the building’s appearance when viewed from different angles, adding an eye-catching effect. The intention was to achieve a monolithic volume above the lush green terrace and a symbolic presence with heavy PC panel walls as seen from the lower part of the riverside terrace. At the main entrance, a large, cantilevered aluminum honeycomb panel canopy with a maximum length of 7.5 meters is installed incorporating a tuned mass damper (TMD) to create a well-defined front-facing appearance.

轮廓分明的外装投下令人印象深刻的阴影，与苍翠茂盛的绿植相辅相成，打造出一个全新的象征性的存在。

The deeply carved exterior casts striking shadows, and when combined with the abundant greenery, creates the presence of a new symbol.

租赁式办公楼的价值追求
Pursuing value as a tenant office

办公专用部分采用去掉角柱的悬挑结构，确保了每层平面形状规整且专用面积达600坪（1 坪 ≈ 3.31㎡），同时还实现了舒适的视野。相对于23m的柱网，通过在设备井内设置斜撑来控制梁高，实现了层高4.25m、天花板高2.8m、进深约20m的无柱空间。

Adopting a cantilevered structure without corner columns achieves a rectangle-shaped leasable area of around 2,000 square meters per floor with comfortable views. To cover a distance of 23 meters between columns, the beam depth is minimized by placing diagonal braces in the equipment shaft, ensuring a column-free space with a ceiling height of 2.8 meters, a floor-to-floor height of 4.25 meters, and a depth of approximately 20 meters.

1层西南角上设置的入驻者专用休息区面对着一片丰盈的绿意，悠闲舒适的环境可供人们在此享用午餐或稍作休息，也可用来开会和举办活动等。

The tenant-exclusive lounge, located at the southwest corner of the first floor, faces abundant greenery, offering a relaxed atmosphere for various purposes, such as lunch, refreshments, meetings, and events.

别具风格的材料构建出的丰富空间
Rich spaces created by intriguing materials

外装的PC预制板采用了让人感觉柔和的大地色，以呼应沉稳内敛的地区特征，表面还进行了喷砂工艺加工以突出其质感。入口大厅处采用与建筑外观色调保持一致的大谷石（日本的石材品种，属轻质凝灰岩）和粉体涂装面板，与外部连接的经磷酸盐处理的黑色面板墙面打造出具有张力的空间。此外，用经磨光处理的景观石建造的上升花园，表现了作为市中心珍贵绿色亲水空间而闻名的目黑川的水面，是一个能让人感受到时间和季节变迁的入口大厅。

The exterior PC panels are finished in an earthy color, suitable for the tranquil surroundings, and the surface is sandblasted to emphasize the material’s texture. In the entrance hall, Oya stone and powder-coated panels are used to take in the exterior’s color tones while creating a sense of tension with the black walls of phosphoric acid-treated panels continuous from the exterior. Furthermore, a “rising garden” is designed using polished landscape stones to represent the water of the Meguro River, a famous waterside spot in the center of the city, rich with greenery. This gives the entrance hall a feeling of the passage of time and changing seasons.

具备位移放大机制的集中式消能减震结构设计
Structural planning for a concentrated vibration control building with displacement amplification mechanism

这是一栋高约70m、地上13层的钢结构建筑。在约75m×35m长方形平面的西侧配置交通核，无柱的办公室空间采用U型布局。建筑采用在交通核内部1层设置调谐黏滞质量阻尼器、在上层设置屈曲约束支撑(Buckling restrained brace)的消能减震结构，旨在减少大地震时主体结构的损伤，降低地震与强风时的反应加速度。消能减震设计利用调谐黏滞质量阻尼器集中吸收地震能量，通过上层的屈曲约束支撑提供（结构）刚度，并在发生大地震时通过先于主梁屈服耗能来降低对主体结构的损伤。

This is a steel structure plan with a height of approximately 70 meters and 13 floors above ground. The core is placed on the west side of the rectangular floor plan, which measures about 75m x 35m, and a column-free office space is arranged in a U-shape. The structure features a tuned viscous mass damper on the first floor within the core and buckling-restrained braces on the upper floors, aiming to reduce structural damage during major earthquakes and lower response acceleration during earthquakes and strong winds. The vibration control plan involves using the tuned viscous mass damper to absorb earthquake energy in a concentrated manner and employing buckling-restrained braces on the upper floors to provide rigidity and reduce structural damage by yielding before the main beams during major earthquakes.

调谐黏滞质量阻尼器通过使建筑与阻尼器支撑部具有相近的固有周期，来放大阻尼器的位移，从而使其能够吸收更多的能量。在该项目中，还通过在阻尼器支撑部上配备利用轴销的位移放大机制，来进一步放了大阻尼器的输入位移。结果表明，阻尼器的输入位移能够放大到建筑层间变形的2倍以上，从而能够以较小的阻尼器数量高效集中地吸收地震能量。

The tuned viscous mass damper can amplify displacement and achieve significant energy absorption by bringing the natural frequencies of the building and the damper support structure closer together. In this building, a displacement amplification mechanism utilizing pins is added to the damper support structure to further amplify the input displacement of the damper. As a result, the input displacement of the damper can be amplified to more than twice the inter-story deformation of the building, allowing for efficient and concentrated earthquake energy absorption with fewer damper units.

环境保护设计
Environmentally considerate planning

整个建筑采用节能且长寿命的LED照明，专用区域还采用人感・亮度图像传感器进行日光利用控制和人体存在感应控制，以此实现可节能运行的照明设计。在热环境设计方面，标准层的玻璃幕墙采用双层Low-E中空玻璃，以确保窗户周围具有较高的隔热性能。关于空调分区的划分原则，内部区域按照50㎡左右分区，外围区域则按照柱网细化分区，以实现空调的24小时自由冷暖切换和温度设置。

For the lighting plan, energy-efficient and long-lasting LED lighting is adopted throughout the building. In the leasable areas, occupancy and luminosity image sensors are used to control daylight intake and lighting for energy-efficient operations. As for the thermal environment plan, Low-E double-glazing is used for curtain walls on the typical floors, ensuring high insulation around the windows. The air-conditioning zones are carefully divided so that the interior zones are approximately 50 square meters each and the perimeter zones are divided at every column. This allows for 24-hour flexibility in switching between heating and cooling and adjusting temperature settings.

业务持续性计划（BCP）
Business Continuity Plan (BCP)

发生灾害时，设于屋顶的应急发电机可以为办公专用区域的所有照明设备提供持续开启72小时所需的电量，还可提供单相10VA/㎡・三相15VA/㎡的电源，以及保障卫生间的继续使用。此外，建筑还设置了容纳回家困难者的空间和防灾仓库，具备支援地区防灾的BCP性能。

In the event of a disaster, the emergency generator placed on the rooftop will provide 100% lighting for 72 hours, a power supply of single-phase 10VA/m² and three-phase 15VA/m², and power to continuously use toilets in the office’s leasable areas. Additionally, spaces for accommodating people unable to return home and storage for emergency goods are installed to contribute to the community.

在商用电源的供给上，通过从电力公司引入2条不同系统的电源线路，提高了电力供给的稳定性和可靠性。作为自来水管道无法供水时的对策，通过用塑料瓶储存饮用水，在给水水箱中储存洗手用水，在杂用水箱里储存冲厕用水，以分别确保所需的水量。另外，还对屋顶上收集的雨水进行过滤，作为冲厕所用的中水使用。当下水管道无法使用时，通过切换排水系统，可将污水储存在建筑物内的排污应急池中。

To improve the stability and reliability of power supplies, two separate lines from different systems are drawn from the power company. In case the primary water supply is disrupted, drinking water is preserved in plastic bottles, hand washing water is stored in the water intake tank, and toilet water is reserved in the general service water tank. The collected rainwater on the rooftop is filtered and used for toilet flushing. In the event of a sewer system disruption, the wastewater system can be switched to store sewage in an emergency sewage tank within the building.
