<P class=MsoBodyText>The fraction of the design loop capacity that the chiller
will be sized to meet. This keyword is allowed only if CAPACITY is not
specified. If you are defining two chillers of identical size that exactly meet
the design loop load, set each chiller's CAPACITY-RATIO to 0.5. To include a 20%
safety factor, set each chiller's CAPACITY-RATIO to 0.6. If neither CAPACITY nor
CAPACITY-RATIO is specified, the chiller capacity will default to the loop
capacity divided by the number of chillers attached to the

runs<BR></FONT><BR></DIV>
<DIV></DIV>Hello,<BR><BR>As I mentioned previously, I am creating an energy
model for a LEED project. In "baselining" the building, one of the
stipulations of ASHRAE 90.1 2004 is:<BR>"G3.1.2.2 Equipment Capacities.
The equipment capacities for the baseline building design shall be based on
sizing runs for each orientation and shall be oversized by 15% for cooling and
25% for heating" <BR><BR>I think that means I use "auto-size", but then how do I
capture what that size is and oversize it accordingly? I am guessing that
the results may be in the SIM file. Can anyone provide tips for executing
this? Is there a better way to do that auto-sizing for each orientation?
<BR><BR>Thanks,<BR>Andrew McNamara<BR><PRE>
