Controlling direct sunlight into spaces is necessary to reduce unwanted heat gain and reduce the adverse effects of glare into a work environment, therefore designers must seek to:
Exclude direct sunlight from all learning spaces, libraries, administrative offices and staff studies for the period of 9.00am to 3.30pm including Eastern Daylight Saving Time between 21st September to 21st March (equinoxes).
Exclude direct sunlight from desk level in all learning spaces between 9am and 3:30pm.Sun exclusion and glare control can be achieved by the use of elements such as sun shades, eave extensions, tinted glazing, screens, vertical blades and the like.
Glare must only be controlled by blinds as a last resort.
Designers must prepare sun diagrams in the design phase as a minimum requirement.

If used, perforated sun shades must have small openings, with total perforation less than 20% to avoid dappled glare patterns within the building. Note perforated shades are more expensive and require more maintenance than solid sheet material.
Aluminium is preferable as perforated steel sheeting is also susceptible to rusting and should not be used.
