Solar tower breathing in extremes

Abstract: In downtown Winnipeg, this innovative office environment combines a parkade, a 3-story podium, containing offices, restaurants and retail, with two narrow 18-story office towers linked by winter gardens. Winnipeg with 6,032 heating degree-days, a winter design temperature of - 35°C and a summer design temperature of + 30°C presented the project team with unique climatic challenges. The building dynamically adapts to the continuously changing climatic conditions. Occupants can control their individual environment according to their own personal preference using operable windows, lighting and shading devices. Now under construction, this 65,000 m² building is predicted to consume 140 kWh/m²/year of primary energy for building operation, establishing it as the most energy efficient office tower in North America, 60% below a typical office tower. Beyond energy efficiency the Manitoba Hydro Corporate Head Office will provide a new level of thermal and visual comfort, with all workstations having access to the façade.
