This parametric analysis led to the following high performance design requirements:
• 40-42% vision glazing on the tower, maximizing glazing where shading minimizes solar gain
• Full height shading devices on the northwest façade to address the potential for extensive solar gain caused by the low angle sun
• A combination of vertical and horizontal shading on the southeast and southwest facades—tuned specifically to address solar orientation.
• A light shelf reflector below the window sill to maximize daylight penetration.
