[Bldg-sim] "Qualified" energy modeling tools for LEED NC v2.2

[Larry Degelman]

Hello Zhai Chaoqin:
 
Here is a response from Sonia Punjabi from USGBC in Wash, DC:
 
"LEED Energy and Atmosphere Credit 1 references ASHRAE 90.1.  Section 11 of
90.1 lists criteria as requirements for an acceptable modeling tool.
 
"Because of the wide range of modeling tools being used in the market, USGBC
has not undertaken an initiative to quantify which tools are and are not
acceptable for use to document LEED EA c1.  Generally speaking, most program
architects incorporate the 90.1 Section 11 criteria into their programs.
That said, it is still vital that you verify that the model you are
selecting for use meets the criteria.
 
"Modeling tools that deviate from Section 11 of 90.1 are approved for use in
LEED on a case by case basis.  In certain circumstances modeling tools that
deviate from Section 11 offer a cost benefit that far outweighs any
potential inaccuracy.  It is advisable to submit a CIR that clearly details
the modeling tools deficiencies and why the modeling tool is an acceptable
compliance path for your building program prior to submitting LEED EA c1
documentation that is based on a non-Section 11 compliant modeling tool."
 
Hope this helps!

Does anyone know if USGBC keeps a list of "qualified" energy modeling tools
for LEED NC certification? 
 
Thanks!
