Scott 街联锁信号塔发电机房丨加拿大多伦多丨RDH Architects Inc.

负责监督大多伦多和汉密尔顿地区交通改善的安大略省政府组织Metrolinx委托RDHA事务所设计一个新的应急发电机塔，以取代为多伦多联合车站服务的退役发电机塔。该项目位于多伦多通往Yonge街的Gardiner高速公路西行出口匝道上，紧邻历史悠久的Scott街联锁信号塔。

Metrolinx, an Ontario Government organization that oversees the improvement of transportation in the Greater Toronto and Hamilton Areas, commissioned RDHA to design a new emergency generator tower to replace a decommissioned one that serviced Toronto’s Union Station. The project is sited on Toronto’s westbound Gardiner Expressway off-ramp to Yonge Street, immediately adjacent to the historic Scott Street Interlocking Signal Tower.

Scott街联锁信号塔是1930年由建筑总工程师John Wilson Orrock为加拿大太平洋铁路（CPR）设计的，是同一时期多伦多为加拿大太平洋铁路建造的三座信号塔之一（其他两座位于Cherry街和John 街）。该信号塔拥有意大利风格的圆顶窗户、方形塔楼和倾斜的屋顶，被认为是遗产基础设施的重要组成部分，也是本项目的主要灵感来源。

Designed in 1930 for the Canadian Pacific Railway (CPR) by John Wilson Orrock, the Chief Engineer of Buildings, Scott Street is one of three signal towers built in Toronto for the CPR during the same era (the others at Cherry Street, and John Street). With its Italianate round-topped windows, square tower, and hipped roof, the building is considered a significant piece of heritage infrastructure, and it became the prime inspiration for the new addition.

发电机塔由发电机、结构系统和自然通风的外立面表皮组成，设计旨在尊重周围历史悠久的信号塔，并通过当代建筑语言创造出以水平构图为主的街景立面。项目的总体目标不仅是重新诠释Scott街联锁信号塔，而更重要的是重新吸引人们对城市环境中经常被忽视但非常重要的工程和基础设施的兴趣。

The generator tower, comprised of a generator, a structural system, and a naturally ventilating skin, attempts to respect its historic neighbour, and deliver a similar level of design attention, although through a contemporary architectural language. Our overall goal was to renew appreciation for not only the Scott Street Tower, but also to draw renewed interest towards what are often overlooked, but highly essential, pieces of engineering and infrastructure within the urban context.

设计方法始于对传统建筑的仔细分析，以新建筑暗示该场地中的尺度、规模、体量以及立面构成。由此产生的建筑设计方案是以反射材质与闪闪发光的立面形式对现有塔楼的现代化诠释，立面被基准线分为三个部分，通过轻抛光铝条板的巧妙地打开和关闭，将自然通风与部分视野引入这座基础设施建筑中。

Our conceptual approach began with a careful analysis of the heritage architecture to guide and inform the enclosure’s perception, scale, footprint, and elevational composition. The resulting scheme is a shimmering, and reflective formal interpretation of the existing tower, with three corresponding datum lines of lightly polished aluminum, subtly opening and closing to allow ventilation and partial views into the shrouded piece infrastructural architecture.

项目团队致力于为其进行高度可持续的设计，建筑、工程和材料的选择都是为了长期使用。该建筑采用了被动节能策略，唯一的通风和冷却系统都是通过立面面板的开阖完成的，这些面板可以根据发电机的要求直接打开或关闭。整个建筑采用节能led照明，并配有日光和人体感应设施，以减少全天的能源使用量。此外，新老建筑之间的空间还种植了一系列绿植，形成了绿色的分隔墙。

The project team strove to establish a highly sustainable design, with architecture, engineering and materials designed for longevity over time. The building is essentially passive, as the only ventilation and cooling is through the facade panels that can be either opened or closed in direct response to the requirements of the generator. The building is lit with energy efficient LEDs throughout, with daylight and occupant sensors to reduce the amount of energy used throughout the day. And the reveal space between the old and new structures is designed to allow incorporate a green planted urban wall.

为了与整体方法保持一致，新发电机房被构想为当代城市的重要组成部分，具有建筑完整性，并尊重了城市遗产。它不仅是功能性的基础设施，还是一处有趣的、美丽的工业景观，宛如一座会呼吸的雕塑。

In keeping with this overall approach, the new generator structure has been conceived as a contemporary urban object with architectural integrity that honours a heritage asset. It is also as functional as it is an intriguing, beautiful and breathing sculpture within the industrial landscape.
