How to model Snowmelt System in eQUEST?
The TMY2
weather file has a flag for snowfall that you can export to excel to help
refine your schedule.

eQUEST?
For
projects I have worked on with snowmelt loads, I calculate the energy consumed
by multiplying the snowmelt load by the anticipated runtime hours (based on
bin data of OA Temperature for when the snowmelt system will be used). The load
can then be assigned as a direct load to the natural gas (or electric) meter
under the "Utility & Economics" tab in eQUEST. For simplification, the
load is assigned to a scheudle (I typically just run a 24/7/365 schedule
and revise the input load so that I get the same total annual energy
consumed that was calculated for the snowmelt system) and then assign
the load/schedule to an end use category. For snow melt I use
the "Exterior Usage" end use category.

Yes, I am modeling for LEED. It might be simpler and
easier if Calculating the annual energy consumption for
snowmelting system separately, and somehow
adding it to heating load from eQUEST.
Did you know ASHRAE 90.1-2004 Appendix G mentions anything
about snowmelting? I haven't found yet...

Wow I
am in the same exact boat as you are in. I have a snow melt system that
I need to model and am not sure how to go about doing it. Are you
energy modeling for LEED?
Does anyone know how to model Snow-melt
System with eQUEST?
The building I am modeling has radiant snowmelt systems at
the basement floor.
Please let me know if anyone has modeled before or has any
idea.
