This section summarizes the indoor water factors.
Factors influencing the indoor usage are the number of people occupying the building, which is determined elsewhere in the building model for consistency with the energy analysis; and the percentage of time the building is occupied, where the default percentage is derived from the default occupancy schedule for this building type. The occupancy density of your project can be modified using the Project Templates feature. See Using Project Templates for more information.
The Efficiency settings of fixtures and equipment in the Building Summary section can also influence the indoor water usage. Net-Zero Measures such as rainwater harvesting and potable water sources on site do not reduce the indoor water usage, since they do not change the demand for water indoors, but they do reduce the Net Utility water usage in the Water Usage and Costs section.
