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

[Dónal O'Connor]

Hi all,

Thank you all for your input.

I will ensure my annual DHW usage is consistent with what is specified for the WE credit (showers and faucets), and develop the DHW schedule from there.

Kind Regards,

Dónal

Hi Donal,
Usual LEED 2009 projects base the shower uses on FTE/ visitor/ resident numbers. If you are dealing with a facility that works differently, you'll probably prefer to base your FTE/ visitor numbers on design assumptions or information from the facility owner. It is a good idea to check out with USGBC their opinion on your assumptions before submitting your project. You can to that bty clicking on USGBC's page contact us link.

Good luck,Dionisio FRANCAM Arch, LEED AP+OM, ND

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.

Hi all,



I'm looking for some guidance on how to model the domestic hot water 
load for an indoor soccer facility for LEED. The facility is scheduled 
to be open 18 hours per day, every day, with a potential changeover of 
120 people per hour (if each field has max occupancy and is rented out on an hourly basis). So, 120 people could potentially have a shower 
every hour, however, this is not realistic. I do not want to overestimate the energy savings and have 
the LEED reviewer find fault. Has anybody experience modelling a similar situation 
before?



Thanks
