Limiting the Effects of Solar Gains - Design Measures
Provisions should be made to limit high internal temperatures from excessive solar gains through a combination of window size and orientation, solar protection, ventilation, and thermal capacity. Balanced mechanical systems should include summer bypass functions during warm weather.
Provisions should be made to limit high internal temperatures due to excessive solar gains. This can be achieved by an appropriate combination of window size and orientation, solar protection through shading and other solar control measures, ventilation (day and night) and high thermal capacity. Where ventilation is provided using a balanced mechanical system, consideration should be given to providing a summer bypass function during warm weather (or allow the dwelling to operate via natural ventilation) so that the ventilation is more effective in reducing overheating.
