[Equest-users] District Thermal Energy Modeling for LEED EAp2

[Amber Welsh]

Hi all,

 

I am performing an energy model for a couple buildings with a central
plant and LEED's treatment of district thermal energy says the upstream
(i.e. plant) equipment cannot be included in the prerequisite
calculation.  I have already set up the model and got it going for the
Energy credit with water-cooled chillers and steam fired boilers.  In
order to do the prereq, I have added a steam meter to the HHW loop and a
chilled water meter to the CHW loop.  When I perform compliance
analysis, I get an error stating there is no point in having plant
equipment if the loop in on the meter.  When I delete chillers and
boilers, pumps, and tower - it has errors sizing the equipment.

 

Can anyone offer up advice or point me to a document that explains
clearly the best method?  Thank you.
