This section summarizes the building summary.

The indoor fixture, appliance and equipment counts, not the number of people, are shown in this section. Fixture counts are based on the minimum requirements of the cited plumbing code. Fixture counts can be modified and saved for planning purposes. The number of fixtures in the building does not affect the baseline indoor water usage, since the main driver for water usage is the number of people occupying the building, rather than the number of fixtures available for use. However, the efficiency of those fixtures does affect the indoor water usage, and the fixture efficiency can be improved in this section of the Water Estimator to reduce the estimated indoor water usage. The presence or absence of a cooling tower is determined elsewhere in the building model for consistency with the energy analysis. Water usage due to the cooling tower contributes to the 'Indoor' usage in the 'Water Usage and Costs' section. The efficiency of the cooling tower can be modified to save water, and the cooling tower blowdown water inclusion in sewer costs can be specified.
