Table 18: Total installed loads chart for type 2 retail store. As a final result, the loss table for the hot-water network of the store under analysis is shown in Table 21.  
The results of the automatic export of the results are presented in Figure 13. The obtained data are compiled in a standard plan, displaying views of the structure together with the tables corresponding to the installed flow rates, head losses and meter and sub-meter calculations. This plan is based on the technical format imposed by the RIDAA, whereby the detailed drawings of the meter niche, sub-meters, starter and boiler device are included, resulting in a format ready to be presented in an application for sanitary service feasibility evaluation.
