专修大学神田校区丨日本东京丨日建设计

迎接建校140周年的校园重组 Restructuring the campus to commemorate 140 years

东京神田骏河台到神保町一带大学云集,因此被誉为日本的拉丁区（巴黎著名的学府区）。专修大学神田校区位于神田神保町，与主干道仅一街之隔。在建校140周年之际，作为校园重组计划的核心部分，该校计划新建一座高层教学楼。

The area extending from Tokyo’s Kanda Surugadai to Jimbocho (Kanda Jimbocho) is often referred to as the Latin Quarter of Japan, with many universities located in the vicinity. One block over from Yasukuni-Dori Street, lies the Kanda Campus of Senshu University. The new high-rise building was proposed as a central component of the campus restructuring plan, marking the school’s 140th-anniversary.

高度经济成长期之后,日本曾一度出现过将校园迁至郊区的现象。近年来，为了应对全球化社会和信息化社会的快速发展，以及在出生率下降的不利影响下确保学生人数，各大学包括设施重建在内纷纷迁回城市中心。专修大学也着眼于未来的发展愿景，除了将学部（本科）从神奈川县的生田校区迁回东京外，还将设立旨在培养全球化社会人才的新学部，并以此作为校园重组的核心进行了研讨。

Following the wave of campus relocations to the suburbs during Japan’s post-economic growth period, universities have recently been moving back to the city center to keep up with the pace of globalization and information society, and ensuring student numbers amidst falling birthrates. Based on Senshu University’s future vision, the campus’s reorganization was considered, centering on the relocation of faculties from Kanagawa Prefecture’s Ikuta Campus and the establishment of a new department for human resource development in a global society.

都心型校舍的场地利用 Utilizing the site for a city center school building

本项目在包括生田校区学部搬迁和设立新学部等的校园重组过程中，亟需开发一个能够容纳约3000名学生的教学空间。为了有效利用混杂着邻接地块而错综复杂的场地形状，我们将可容纳400人的礼堂和大教室等需要规整形状和一定规模的功能配置在场地的北侧区域，并在其外周部分配置所需的疏散楼梯和设备用房，以此形成设备功能合理且能确保采光的有效布局。

For this project, a facility that could accommodate some 3,000 students was necessary, because of faculty relocation from Ikuta Campus and the creation of new departments. To make maximum use of the site which was complicated by protruding adjacent plots, functions that require large square spaces, such as a 400-seat auditorium and main classrooms, were placed on the north side. Around this, evacuation stairwells and utility rooms were reasonably placed, in a way to ensure adequate daylight.

对于复杂的场地形状，我们既没有用体量去填充，也没有用门墙围起，而是通过将低层部分的脚下空间做成架空层，形成了一个充分利用场地形状的通道空间。该建筑被定位为校区的新门户，向城市开放并与城市融为一体，同时考虑到了与北面既有校园建筑群的连接以及始自饭田桥、神保町和九段下地区的来校动线。

Pilotis wrap around the lower floors to enable pedestrian passage, instead of filling up the complex space or enclosing it within walls. By connecting to the existing group of buildings to the north and improving foot-traffic from the Iidabashi, Jimbocho, and Kudanshita areas, it is positioned as a gateway into the campus that is open to and incorporates the city.

建筑中散布着培养主体性和增加可选项的设计 Mechanisms that foster independence and increase choice

如今，不仅办公环境要求多样化的工作方式，就连教育学习环境也在要求形式的多样化与灵活性。在设计阶段的学内研讨会上就提出了“随时随地主动学习”的主题，旨在积极利用被隔出来的教室和其他地方作为学生自主学习的空间，并在研究过程中将这一主题融入到有限的场地和高层校舍条件中。为了应对下课时大量学生在教室间的移动需求，高层教学楼必须进行相应的运送规划。本项目除了运送学生所需的电梯、自动扶梯和疏散所需的疏散专用楼梯外，还设置了以邻近楼层间移动为主要目的的楼梯功能等多个纵向移动竖井。

In the same way as office environments nowadays are changing to support a variety of work styles, diversification and increased flexibility are also required in education and learning environments. “Active Learning Anywhere” was the theme the university’s deliberation committee shared during the design phase, aiming to provide locations besides the enclosed classrooms as proactive spaces for students’ self-study. This idea was explored under the conditions of a limited site area and a high-rise structure. Planning the circulation for many students as they transfer between classrooms during breaks and other activities is essential in high-rise school buildings. Other than the basic elevators, escalators, and specialized evacuation stairwells, many vertical circulation shafts are provided, including stairs designed for access to nearby floors.

在高层教学楼中，学生可以在教室以外自主使用的空间分布在由于功能所需而不得不堆叠在一起的走廊、电梯厅以及楼梯和自动扶梯等具有洄游性的动线上。在这栋场地和建筑面积都有限的高层教学楼中，我们重新审视了教室以外的剩余空间和单纯移动空间这些所谓的共用部分，并将其作为培养学生主体性的场所为其赋予新的价值。这样做的目的是增加学生们对多样化学习方式的选择余地，并使整个教学楼成为一个培养学生主体性和多样性的容器，让学习的火花始终在教学楼的某个角落绽放。

Proactive learning spaces for students are scattered along hallways, elevator halls, stairwells, escalators, and other lines of circulation unavoidably stacked for functional purposes. For this high-rise school building, restricted in both site and floor area, any extra space and simple circulation areas outside the classrooms, so-called “common spaces,” have been reframed as places for students to cultivate their independence. The aim was to accommodate students’ diverse choice of learning styles, to keep the spark for learning lit throughout the school building and become a springboard for the development of student independence and individuality.

校园和城市的新地标 A new landmark for the campus and city

与北侧相对外部较为封闭和环境稳定的教室空间不同，面向主干道的建筑南侧则集中了电梯、自动扶梯、楼梯等洄游动线和阳台等交错的活跃空间，可以说学生们游走其间积极主动的活动态势就像是整个教学楼的血液循环一般充满了生命力。这栋新建的16层的高层教学楼，继承了当年竣工时跃居日本最高教学楼的现神田１号楼，成为了向神田校区和城市传达面向下一代的大学愿景的新地标。

The proactive spaces, blended with circulation functions such as balconies, elevators, stairwells, and escalators, are gathered on the building’s south side facing Yasukuni-Dori Street. In contrast to the north side, which is a more enclosed and static environment, the south facade reveals the students’ independent spirit and activities, running like veins throughout the entire building. This new 16-story high-rise is the successor of the existing Kanda Building No. 1, which was the tallest school building in Japan at the time of construction. It continues to be a landmark for Kanda campus and the surrounding city, projecting the university’s vision for future generations.

利用高层教学楼挑空空间的教育机制 Using the atrium as an educational device

在贯穿高层教学楼的挑空空间中，设置楼梯功能以便于在课间移动至邻近楼层。这个楼梯功能由三种形状构成，除了作为课间移动手段的必要功能外，还是促进学生学习、交流和活动的装置。另外，还在由楼梯功能的形状变化所产生的空间中设置了一个阳台，作为学生们的休息空间，而这往往是都心型校舍所普遍缺乏的，同时还作为与外部的接点有助于将自然通风导入建筑内部。通过将这个楼梯功能和阳台、洄游动线上的自动扶梯都内置于一体的挑空空间中，让学生们移动活动的样子在视觉上也立体交错，从而形成仿佛方形纸罩座灯一样的空间。

Stairwells with three different design configurations are installed in the atrium space penetrating the high-rise school building, providing access to nearby floors. Besides serving for circulation, it is a device promoting student learning, exchange, and engagement. Additional spaces produced by shifting the shape of the stairwells are turned into balconies, as places for students to rest and enjoy the outdoors, facilitating natural ventilation. By combining these stairs, balconies, and escalators within one atrium, the students’ flow and activity are three-dimensionally and visually mixed, resulting in a lantern-like space.

利用高层教学楼的空间结构，在挑空空间的顶部设置一个通风窗用于重力通风。在春秋等适合自然通风的气候条件下，通过设于外部的风雨传感器打开挑空顶部的通风窗进行重力通风。此外，设于各处的阳台出入门的上部还设置了内照式的“环境标识”，在实际设施运用中，鼓励作为使用者的学生也作为环境教育的一环积极参与其中。当标识亮灯时，学生们通过打开房门将室外空气积极导入建筑内部，在感受风的流动的同时，促进了利用高层校舍挑空空间的自然通风效果。校舍本身也起到了环境教育的作用，让肩负未来环保时代重任的年轻人在日常的校园生活中接触到环保意识和节能措施，这包括安装在室外长椅附近的干雾系统以及利用保水性砖瓦在夏天体验洒水降温的效果。

Topping the atrium space is a ventilation window to generate stack ventilation, making full use of the spatial organization of the building. With wind and rain sensors placed on the exterior, the ventilation windows are opened automatically when weather conditions are favorable, for example in the intermediate seasons. Internally lit “environmental signs” are placed above the doors to the balconies to notify students to open the doors and take in the outside air, experiencing the breeze and the atrium’s natural ventilation effect. Other devices such as dry mist dispensers placed near outdoor benches and water-retaining brick tiles create a cooling effect in summer. The building is intended to contribute to environmental education, encouraging young people, leaders of a sustainable future, to increase environmental awareness and reduce energy use in their everyday campus life.
