Performative Design Examples

Manitoba Hydro, Canada

In sustainable skyscrapers, priority has been given to passive systems of heating and cooling over active- and mixed-mode systems because it consumes lowest energy from renewable resources. The Manitoba Hydro tower is 18-story office building, which will feature “bioclimatic” design adapted for the Canadian climate.

Manitoba Hydro, Canada, was completed in 2009 (see Fig. 7.3). It is the primary energy utility in the providence of Manitoba, the fourth largest energy utility in Canada, and it offers one of the lowest electricity rates in the world.

The site was specifically chosen because of its closeness to public transportation routes and the untapped opportunities to design a building to harvest passive solar heating and daylighting. The orientation and massing strategies were carefully analyzed to optimize the potentials of the site (Fig. 7.4).


Manitoba Hydro is located in Winnipeg Manitoba, which is one of the coldest cities in the world. The climate and temperature of Winnipeg is extreme and fluctuates dramatically over the year. Winter temperatures average around -35 °C, increasing to +34 °C by the summer time. The severe climate of Winnipeg has 8.9 m/s winds in the wintertime but also it is very sunny during cold season that results in an opportunity to incorporate passive solar heating and daylighting which reduces the lighting loads and creates hybrid ventilation (Fig. 7.5).
