格林伍德学院位于多伦多市中心，本次扩建项目的建筑面积达7万4千平方米。这座布局紧凑的四层建筑将学校的各层相连，使得原有的建筑面积增加了120%。通过高效利用有限的土地，校园的工作空间和社交空间形成了平衡的关系，同时带来更多个性化的新型教学空间。

Designed by Montgomery Sisam Architects Inc., the Greenwood College School Expansion is a 74,000㎡-building addition located in mid-town Toronto. The dense, four-storey structure adjoins the existing school at every level above grade, increasing the School’s square footage by 120%. Making efficient use of limited land, it features a balanced mix of work spaces and social space that supports a personalized, new-century approach to learning.

设计概念 | Concept

以竖立在校园中心的标志性的攀岩墙为开端，该扩建项目旨在为不同的教学体验打造多样化的空间形态，同时在有限的建筑空间中容纳社交、文化和娱乐等功能。建筑的混凝土体量遵循了标准化的网格框架，以便适应未来的功能调整。建筑的南侧是宽敞而灵活的教室，为合作式教学和跨学科教学提供了充分的空间。

Taking its cues from the landmark climbing wall erected in the heart of the existing school, the Expansion is designed to create a varied geography of spaces that support a diverse educational experience – one that integrates academic programs with social, cultural and recreational pursuits within a tightly packed building envelope. Its concrete structure with standardized structural grid assures future adaptability as programming evolves. Large, flexible classrooms, stacked along the south side accommodate increasing initiatives in co-teaching and interdisciplinary programming.

基于开放且具有整体性的平面布局，连贯而自由的活动空间将这些教室与设备先进的音乐教室、视觉艺术教室、数字媒体教室、剧场和体育场连接在一起，这些空间和玻璃立面的楼梯间共同为不同的楼层和平面赋予了积极、活跃且互联的氛围。

An open and integrated floor plan connects these classrooms with specialized, state-of-the-art spaces for music, visual arts, digital media, theatre and athletics through a free flow of casual student spaces. These spaces, together with a glazed feature stair, promote activity, movement and interconnectedness across each floor and between building levels.

环境 | Context

本次扩建为多伦多的城市环境和居住环境都带来了积极的影响。通过对巷道的调整和重置，新的建筑修复了城市中的裂痕，使校园围合得更加紧密。移动后的巷道还改善了交通流线，使学校的交通能够独立于周边社区而存在。原先的灰泥立面得到了扩建，为建筑创造出新的入口。新的门廊不仅增强了学校在主干道上的可见度和辨识度，还在附近住宅与繁忙的公路间建立了一个缓冲区域。

The Expansion creates a positive condition in the City that both respects and engages with its urban, residential context. With the relocation and reconfiguration of a laneway, the building repairs urban fragmentation to create a seamless school property. The diverted laneway also improves traffic flow patterns and isolates school traffic from that of the surrounding community. The extension of the existing stucco façade along the front elevation produces a new accessible entry porch. The porch both enhances Greenwood’s visibility and presence on a major arterial road and serves to buffer neighbouring houses from this busy transit way.

建筑的南端高度降为3层，砖砌的体量迎合了相邻住宅街区的尺度和材料。屋顶露台在拥挤的都市开辟出一片难得的空地，并将室内教学空间直接与能够俯瞰城市的室外空间相连。首层宽阔的落地门窗和楼上具有特色的楼梯间连接了校园与街道的生活，景观设计更使建筑立面前方的人行区域得到突显。停车场和服务空间位于建筑后方，使校园内部和周边的公共区域得到了完善。

The building’s south end is reduced in height to a three-storey masonry block in deference to the scale and materiality of the adjacent residential street. The rooftop terrace is designed as a destination, affording a rare opportunity in a dense urban setting to connect interior teaching spaces directly to the outdoors with views overlooking the city. Expansive glazing along the ground floor façade and up the feature stair connects the life and animation of the school with that of the street. Landscaping initiatives enhance the pedestrian realm along all street frontages. Parking and service space, reduced to a minimum at the rear of the building, maintain the integrity of the public realm, both in and around the School.

可持续性 | Sustainability

格林伍德学院的扩建项目获得了LEED的金级认证。学生们可以通过用于统计能耗的内联网了解到各种类型的控制系统。这些系统能够减少建筑的运行成本、降低建筑对环境的影响，同时有助于对学生进行关于日常能源消耗以及绿色建筑实践的教学。

The Greenwood College School Expansion is registered LEED Gold, with certification pending. A full range of metering systems are installed allowing students to access, through the intranet, a breakdown of energy use statistics for the building. These systems serve to decrease building running costs and reduce its impact on the environment, while educating students on daily energy consumption and green building practices.
