daylighting, and climatic impact through computational fluid dynamics, wind analysis and energy modeling. The final solution is a hybrid of formal process and serendipity. The energy consultant rotated one of the splayed tower schemes to position the stacked atriums due south to capture Winnipeg’s abundant sunlight during the winter and strong southerly winds. It was dubbed the “Solar Tower” and became the preferred option. The tower form itself functions as a passive solar collector. The east and west office lofts are splayed open at the south end and separated by winter gardens that maximize solar heat gain. The lofts meet at the north end of the tower, reducing direct northern exposure and minimizing heat losses. Double Façades A glass tower in Winnipeg’s extreme climate was ironically logical. When it is extremely cold, it is also very sunny, ideal for solar gains. The reduction in heating demand for Manitoba Hydro Place is largely due to a high performance double façade curtain wall design. Above Atria at the north end of the tower collect exhaust air from adjacent floors. Dampers at the chimney intake are used to balance the stack effect throughout the tower height. This exhaust plenum doubles as a break space for employees. Left The Public Galleria connects the streets through the entire city block, creating a public pedestrian throughway. The galleria also hosts farmers markets and charity events. © Tom Arban 8 HigH Performing Buildings fa l l 2 0 1 1 © Tom Arban
