[Greenbuilding] Toilet Frequency of Use

[Kirsten Flynn]

For LEED they assume two liquid flushes and one solid flush per person per day, when calculating the GPF of duel flush toilets.  For full time  occupant female in a workplace they assume 3 flushes, and for male they assume one WC flush and two urinal flush- so this makes a difference only if you have a urinal.  For full time  occupant in a residence they assume 5 flushes for either a male or female occupant.
