M a n i t o b a H y D r o P l a C e Manitoba Hydro, the province’s sole energy provider, began planning for a new, energy-efficient headquarters in 2002. The design team soon realized that the extreme climate of Winnipeg, Manitoba, actually provided a rich opportunity for harnessing the abundant solar and wind energy to operate the building using more passive systems. he program called for a 690,000 square foot building on a full block in downtown Winnipeg to accommodate 1,800+ employees. One goal was to reduce energy consumption 60% below Canada’s Model National Energy Code Building (MNECB). Manitoba Hydro also wanted to create a landmark building with signature architecture that contributes to the revitalization of downtown Winnipeg. However, the primary purpose of the building was to create a healthy, supportive workplace for Manitoba Hydro’s employees. Winnipeg’s extreme climate was initially perceived as a challenge to the energy reduction goals. The city’s temperature annually ranges 70°C (126°F), from –35°C (–31°F) in the winter to +35°C (95°F) in the summer. However, Winnipeg also receives more sunlight than most major Canadian cities, and has an unusual abundance of strong southerly winds. The building team Opposite The solar chimney at Manitoba Hydro Place (in the forefront of the building) passively exhausts air in summer, spring and fall. In winter, fans draw the exhaust air down to ventilate the parking garage and for recovery of exhaust heat. The building reduces energy use by 60% over the Model National Energy Code of Canada without using on-site renewable energy. T realized that the climate challenge actually presented an opportunity to reduce energy use and create a healthy workplace. Design Charettes The design charette is a critical tool in the IDP to advance integrated thinking and solutions. Fifteen building form options were generated for evaluation and testing and three options were selected for detailed development and analysis to test passive efficiencies, b u i l D i n g at a g l a n C e name manitoba Hydro Place location Winnipeg, Canada owner manitoba Hydro Principal use Corporate Head office includes office space, meeting rooms, conference center. employees/occupants 2,000 occupancy 100% gross square Footage 823,535 Conditioned space 695,241 distinctions/Awards 2009 Council on Tall Buildings and urban Habitat — Best Tall Building (Americas) 2010 Archdaily Best office Building 2010 royal Architectural institute of Canada urban design Award 2010 American institute of Architects CoTe Award 2010 engineers Canada Award Total Cost $283 million Cdn Cost Per square Foot $400 Cdn substantial Completion/ occupancy Fall 2009 Project Charter Manitoba Hydro mandated the project be designed, developed and delivered using a formal integrated design process (IDP). An essential first step of the IDP is to determine the project charter. The project charter clarifies the project goals and is continually referenced for every major design decision. Manitoba Hydro’s project charter contained six core goals. 1. To create a supportive workplace environment for the employees of manitoba Hydro; 2. To create an energy-efficient design; 60% reduction in energy consumption from the mneCB; 3. To create a design that achieves a leed gold certification; 4. To develop signature architecture integrated throughout the building at different scales from street level to the roof; 5. urban design — to achieve a high level of urban integration to revitalize the downtown; 6. To achieve a cost-effective building design solution that has measurable benefits to manitoba Hydro in terms of comfort, operations, and maintenance. Fa l l 2 0 1 1 HigH PerForming Buildings 7
