The new 707 Fifth "AAA" office tower in downtown Calgary, Alberta, features a distinctive, curved glass appearance with high energy-efficiency and a comfortable interior. In spite of the cold climate, the 27-story, 564,000-square-foot building met its energy targets, due in part, to the use of Technoform's TGI Spacer M in the triple-glazed, curtain wall system. The project is designed to achieve LEED Gold certification through the Canadian Green Building Council.
World-renowned architects Skidmore, Owings and Merrill (SOM) designed the iconic, energy-efficient structure. The building's façade combines convex and concave forms to shape elliptical and undulating elevations. The floor-to-ceiling glass maximizes internal daylighting and comfort, minimizes unwanted solar heat gain and heat loss, and provides panoramic views of the city and the Rocky Mountains.
The building's lead tenant is PetroChina, whose employees and visitors have a choice of nearby transit solutions and a breadth of on-site amenities, retailers and restaurants. The soaring 30-foot-tall lobby and interconnected winter garden provide an attractive, year-round setting.
