question about steam meter

Dear folks,

I am simulating a LEED-certified building. Purchased steam is provided to
the proposed design. Baseboard radiation using hot water that is exchanged
from purchased steam is used to heat the zone. In Equest, the zone heat
source is defined as STEAM. Chillers are of absorption-type connected to a
hot water loop, which is actually a steam loop.

After the simulation, my problem is that energy use for the space heating is
zero in the sim file. Please advise what is the proper setting for such a
baseboard system in Equest.

Please also advise what is the proper practice to set purchased steam.
Thanks in advance.

Hello Modelers.

I am looking for information/experience with applying the ASHRAE
90.1-2004 , Appendix G for labs.

It is well known that Appendix G cannot be used properly for labs. The
ECB and Labs 21 fixed many of the problems and now they are part of the
2007 version ( not as addenda to the 2004 version). USGBC refers to the
2004 version , but also allows the use of 2004 addenda (per USGBC memo
from April 26 2007). I am wondering if anybody knows what is the
position of USGBC regarding the 2007 appendix G changes.

Thanks

Did anyone respond on this?
As best as I can tell, addendum ac to 90.1-2004 revised the Ch. 6 fan power limitation but not Appendix G's baseline fan power. But now in 90.1-2007, Apdx. G looks aligned with Ch. 6.

Thanks (and I am trying to show my appreciation for all the volunteers who craft these rules by following them),
