[Bldg-sim] Domestic Hot Water Profile for Indoor Soccer Facility

[Jeremiah Crossett]

My experience is to develop a diversity schedule that seems reasonable,
then so long as you keep it the same for the proposed and the baseline it
would be fine. If there is a MEP on the project you should have a peak flow
rate, the peak should be dictated by MEP assumptions, while your schedule
should coincide with MEP WeP1 calculations, that are based on the building
basis of design from the architect and owner assumptions.   The section 1.4
tables provided by USGBC have a section that I found useful in making
assumptions, and also for documentation, see attached example.. For the
attached I used the LEED projects use WeP1 calculations done by MEP for
flow rates based on occupant male vs female. The baseline water use from
the calculation had larger flow rates, also energy savings are achieved by
lower flow rates from the water efficient low flow hot water shower heads
and faucets in the proposed.
