[BLDG-SIM] eQUEST: Central Chiller for Baseline?

[Sam Mason]

Yoko,

In note 5 under Table 11.3.2A, 90.1-2004 says for systems using
purchased chilled water, no chillers shall be modeled and CHW costs
shall be determined using the adopting authority's utility rates.  For
both the baseline and proposed buildings, you would not include central
chillers and instead use purchased chilled water.

Hi, everyone,

 

I am modeling a building that is served chilled water from a central
chiller, and the building doesn't have any individual chiller. 

I am wondering if  the baseline model (by ASHRAE 90.1-2004) should
follow ASHRAE specified "type and number of chillers" (TABLE G3.1.3.7,
ASHRAE 90.1-2004) depending on building conditioned floor area, or it
should be modeled with a Central chiller as proposed/designed model.  

 

Thank you for your help
