Hello, I have assigned two fixture usage groups within a building; A daycare usage group (12 FTE) and General Office usage group (140 FTE). The daycare has the same fixtures as the office space. Which usage group do I assign these fixtures to?? (perhaps I am miss-understanding the concept of fixture groups). Or do I include the fixtures twice, one with Daycare usage patterns and one with general office? Your help is much appreciated.

Hi Padraic, If the daycare and office project occupants have similar usage patterns and utilize the same fixtures, one fixture usage group may be used to represent the entire building occupancy. The form will automatically calculate the daily usage rates for each fixture based on the percent male/female as entered in the Fixture Group when the group is assigned to each fixture. Fixture groups are meant to define occupant groups (i.e. office, warehouse, retail, etc.) that either use a different subset of flow and flush fixtures and/or have different usage patterns.
