Abstract

Rules of thumb in daylighting are often regarded as a universal principle that can be applied in any geographical location. For example, the 20-25% window area to floor area ratio is a well-known daylighting rule of thumb proposed by various researchers in Europe and in the United States. However, very few researchers have provided testimony to the applicability of this rule in other regions. Previous daylighting simulation work using Lumen Micro 8 has testified to the validity of this rule of thumb in Sydney, Australia. Current simulations carried out using AGi-32 lighting software cover latitude deviations away from Sydney to include those closer to the equator and the south pole. The daylighting simulations also address variations in window area to floor area ratios. Limitations of the window area to floor area ratio rule of thumb in other latitudes are thus identified.
