Summary: For natural ventilation to work, solar gains through the
facade needed to be reduced by approximately 80% from
peak conditions. Three steps were taken to reach this
threshold.
1) Reduction of glazed area of the facade by 41%. The
team undertook studies of options to reduce glazing
area, while maintaining a visual transparency and
connection to the outdoors and prioritizing glazing
higher in the wall, contributing more to daylighting.
2) High performance glazing. The team selected a Solarban
70 XL, which resulted
in an equivalent visible
transmission to the
originally selected
glass, but better
solar performance,
cutting solar gain by
34% compared to the
originally specified
glass.
