Re: [TRNSYS-users] residential water load profiles

[Daniel Bergey <daniel@buildingscience.com>]

The DOE has some modeling recomendations for gallons per day (based on
house size and number of bedrooms), and schedule during the day:

http://www1.eere.energy.gov/buildings/building_america/analysis_spreadsheets.html

In particular, the "Standard Benchmark DHW Schedules".  The link to
"House Simulation Protocols" explains a little where these come from, I
recall.

These are probably accurate enough if water usage isn't the main thing
you are studying, although I think some of the data are a bit old.
