26 Climatic Responsive Design Buffer Zones Atria Double Facade

27 Solar chimney provides natural exhaust Double facade used as a buffer zone provides natural ventilation (0-40 C) North atrium ( 3 story) used as a cafeteria (18-28 C) Quality of Buffer Zones South atrium (6 story) used as a semi-conditioned cafeteria / meeting space (10-35 C)

30 Climate and energy concept: summer Six story tower module solar shade and high openings remove solar gains chilled water fall for cooling and dehumidification - + naturally-driven exhaust through solar chimney via north atria C - 30 C - + per floor air handling units for fresh air distribution supply air C slab cooling C - 30 C 16 C - 40 C - + fresh air supply through facade - + per module fresh air supply unit deactivated

31 Climate and energy concept: winter six story tower module solar chimney water dispersion and water fall for humidification C - 23 C - + solar preheating of supply air per floor air handling units for fresh air distribution supply air C slab heating exhaust air into north atria and solar chimney C - 23 C facade closed in winter 10 C - 20 C C - + per module fresh air supply unit + auxillary heating for extreme winter conditions highly efficient heat recovery from exhaust to fresh air central exhaust fan & heat revovery coil 4 C exhaust air for parkade heat and ventilation
