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

[Jim Dirkes]

Dónal,
There are a lot of variables!

·         Men or women?  (shower length may vary :))

·         How many shower vs leave without showering?

·         Seasonal diversity? (warm months probably have  lower occupancy)

·         Daily diversity? (weekends may see greater use)

ASHRAE 90.1's User Manual does not address this type of occupancy, so I would interview the owner or facility manager and ask a lot of questions to assess these patterns.  If you have the best available data from your client, I doubt that LEED reviewers will quibble.  It will help the reviewers to explain the basis for your calculations.  I think they will appreciate a thoughtful and conscientious modeler.

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

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

Dónal
