However, on a <u>SINGLE </u>(<i>emphasize single) </i> housing authority project I worked on, where we had a contract to follow up/calibrate our energy model 1 year after construction, we had real metered water data and found out that the occupants were actually
using only about 12.5 gal/occ/day. They had low-flow fixtures plumbing fixtures, but it still was about half of the value we estimated at the time of modeling.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I did some “Handbook refreshing” in response to this discussion thread and that is indeed the current case (2015 Applications, page 50.15, Table 6 footnote).
The ESMFHR guidelines are a very good resource for multifamily/residential scenarios & a model I’d recommend reviewing for other cases as well.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">If however you’re dealing with service hot water consumption cases falling outside of typical residential/multifamily context, I might be inclined to fall back
on Applications’ suggested baseline gal/day/person DHW consumption guidance for other building occupancy types. If carrying this into an energy model, I might also consider either using the hourly flow profiles (Fig 24, a few pages following), and/or the
ASHRAE “standardized” fractional schedules for various building occupancy types featured in 90.1-1989 & carried forward into a bazillion other energy standards/references.<o:p></o:p></span></p>
