[Equest-users] Hot water use (gal/person/day) in residences in eQuest 3.65

[Nathan Miller via Equest-users]

Single family or multifamily application?

If multifamily, I also recommend the methodology from the Energy Star Multifamily High Rise Simulation Guidelines. This is the basis for modeling LEED for Homes Midrise projects, but we’ve also used it on LEED-NC jobs and the reviewers seem to appreciate using this relatively comprehensive data for multifamily energy model inputs (not that the protocols are without flaws, but at least it establishes a level playing field).

It also gives a methodology for taking credit for low flow plumbing fixtures and energy star appliances to reduce DHW flow in multifamily jobs.

There is a performance path calculator you can download on the source page that already has the calculations set up for you.

Jose,

You can find the residential hot water consumption data starting on p. 50.13 of the 2015 ASHRAE HVAC Applications Handbook.

To whom it may concern:

What is the hot water use (gal/person/day) in residences according to the ASHRAE manuals?  Any comments will be highly appreciated!

Kind regards,

Jose Luis Bermudez Alcocer, Ph.D., M.Arch., B.Arch.
