项目地点 加拿大埃德蒙顿

设计单位 Dub Architects

总建筑面积 5250平方米

建成时间 2019

Edge是一座10层高的办公楼，建在15米宽的地块上，其特色太阳能墙体是加拿大最大的太阳能墙之一，墙面上560块光伏电板可满足建筑80%的电力需求。建筑在晴天时收集电能，并与城市电网相连。

The Edge, a 10 storey office building, built on a single 15m wide lot, features one of Canada’s largest solar walls. Its 560 photovoltaic panels provide 80% of the building’s electrical requirements. The building is connected to the city’s power grid, returning excess power on sunny days.

设计结合了三/四层玻璃系统进行隔热。在夏季，建筑几乎无需人工照明。北侧的开放楼板被柔和的日光自然照射，窗户亦无需设置百叶。同时，建筑尽端设有大型隔热阳台和太阳能屏风，以控制阳光的介入。

The design incorporates both insulated triple-glazed and quadruple-glazed systems. The open floor plates are naturally lit by comfortable north daylight. The north windows require no blinds and the building requires little artificial light during the summer months. The ends of the building feature large thermally-separated balconies and solar screens to control sunlight.

该大楼包括贯穿七层的私人教育空间，私人办公空间在顶部两层。一层大厅朝街道开放，界面可根据不同用途灵活开合。大楼具有18个地下停车位，车辆可通过大楼旁边公寓的停车场进入，一定程度上消除了坡道对地面的破坏。

The development contains private educational facilities throughout seven floors, and private office space on the top two levels. The ground floor engages the street with changing pop-up uses in the open lobby. Eighteen underground parking spaces are accessed through the condominium apartment parkade next door, eliminating the need for a disruptive ramp at ground level.

太阳能墙作为该项目的重要因素，为大楼提供了可持续的效益。南侧的相邻建筑是一个新的仓库改造项目，也由Dub Architects设计，预计50年内无重建计划。而太阳能墙的投资回收期只需5至8年，这使得太阳能墙方案在项目所处场地极具可行性，它将促使建筑每年减少26吨的二氧化碳排放量。

The solar wall provides sustainable benefit and is a prototype for similar infill conditions. Here, the adjacent building to the south is a recently repurposed warehouse (also by Dub Architects) with no anticipated redevelopment for 50 years. However, the solar wall has a payback period of only 5-8 years, making the prototype highly feasible in comparable locations. The solar wall will save 26 tonnes of CO2 from entering the atmosphere annually.

该项目简洁的室内设计有效降低了建筑成本。室内楼地板既支持开放的空间布局，亦可承载沿北墙布置的10间封闭办公室。热泵和照明设备围绕建筑核心，沿混凝土天花展开，裸露在外，便于拆卸；风管沿横梁布置；电路系统设置在楼地板的管道内。

The flexible interior floor plate accommodates open planning or up to 10 enclosed offices along the north wall. Minimalist interiors kept construction costs very low. Heat pumps and lighting serviced from the dropped ceiling along the core allow for an unobstructed exposed concrete ceiling, convenient for demising. Air ducts are supplied along the beams and electrical floor outlets are served by ducts within the poured concrete floor.
