For crit1b and crit1d, it can be assumed the equivalent modelled water consumption (110 or 100 litres per person per day) has been achieved, where the following conditions have been met:
• the specified water fittings meet the standards outlined in the ‘Water fittings standards’ table
• waste disposal and/or water softener are not specified and
• either a bath and shower or shower only are specified
In this instance, the water calculator tool does not need to be completed. However, all other evidence must be provided.
