In more detail, our aim was to (a) fulfil the set performance requirements focusing on the solar performance, g-value of the glazing and g-system value (glazing + shading) and (b) provide a solution that allows for good views out and real-life daylight benefits. When assessing the frequency of shading use we considered the limits for transmitted solar radiation as set by the HVAC consultants and when necessary we took the initiative to make reasonable assumptions.
