The Edge, a 10 storey office building, built on a single 15m wide lot, features one of Canada’s largest solar walls. Its 560 photovoltaic panels provide 80% of the building’s electrical load. The building is connected to the city’s power grid, returning excess power on sunny days. The design incorporates both insulated triple-glazed and quadruple-glazed systems. The open floor plates are naturally lit by comfortable north windows, requiring no blinds and little artificial light during the summer. The building features large thermally-separated balconies and solar screens to control sunlight.
