[Equest-users] District Thermal Energy Savings

[Cam Fitzgerald]

Mathew,

 

Before you submit a CIR (now called LEED Interpretations - LEED 2009),
you should be sure to review the revised DES modeling methodology (v2.0)
that is available on the USGBC web site. I believe it addresses your
situation and it definitely provides clearer guidance than the original
document. You can access it using this link:
http://www.usgbc.org/ShowFile.aspx?DocumentID=7671.

 

Hope this helps, if not you may be stuck with getting an interpretation.
Have a great day!

 

Cam Fitzgerald

Matthew, depending on the size of your building, your baseline may not
have a CW loop, in which case the intent of being cost-neutral towards
thermal energy not generated inside the LEED boundary is satisfied.
Agree on the suggested CIR, however.

The DES definition uses the terms "thermal energy" derived outside the
LEED project boundary.  You could certainly make the case that your
condenser loop fits this definition.  Might be worth submitting a CIR
for clarification though.  Changing your baseline after the fact is
never fun.

Does anyone have experience with district thermal energy by means of a
central condenser water loop? I'm trying to determine whether this type
of application is subject to the LEED District Thermal Energy
Guidelines, like purchased CHW and Steam, or if I can compare to a
baseline system in Appendix G based on building type/size. 

Thanks!
