How best to enter unit heating and cooling loads?

Hi,

What is the best way to get the oversized capacities for the air-side units? I took the zone loads from a simulation run and multiplied them by the required factors and then plugged them into COOLING-CAPACITY and HEATING-CAPACITY. Is this correct?

SIZING-RATIO - SYSTEM sounds right, but there's no way to enter different factors for heating and cooling.

Thanks!

Mark,

In the system properties for your air-side system, you can enter the
COOL-SIZING-RATIO and HEAT-SIZING-RATIO under the Cooling and Heating
tab right below the COOLING-CAPACITY and HEATING-CAPACITY. So if you
want the heating capacity oversized by 25%, you would enter 1.25 for
HEAT-SIZING-RATIO.

Thanks,

Thank you, Matt! That also cleared a warning I was getting. Looks like I have a legit baseline run, now ? or will, once I get some guidance on the makeup air unit? ?
