SummerTypical and WinterTypical are not valid keywords
there.
You have to specify typical in the RunPeriod for sizing, if you want to
use those for the sizing calcs. (And still specify the schedules
for SummerDesignDay/WinterDesignDay)

Thanks Karen. I used 99.6%
heating design conditions for WinterDesignDay and 1% cooling design
conditions for SummerDesignDay from the weather file in the SizingPeriod
and also changed it in the schedules and it works, but I'm just curious
to know why it doesn't size using the typical conditions from the weather
file.

Hi Aber,
In "Zone Control Type Sched" you need to use SummerDesignDay
and WinterDesignDay instead of SummerTypical and WinterTypical.

- Another thing I notice in the sensible heat gain summary of the
output report of the same file is that opaque surface conduction and
other heat addition is zero for zones with surfaces exposed to the
ambient. The exposed surfaces boundary condition type is outdoor and is
exposed to the sun and wind. Any idea why this could be
happening?

- Hi,
- I'm getting the following warning for all the zones while trying to
model a building located in climate zone 1.
- ** Warning ** Calculated design cooling load for zone=OS:THERMALZONE
7 is zero.

ZoneControl:Thermostat inputs.

- I have used ZoneInfiltration:DesignFlowRate for the infiltration of
1.024 l/s/m2 using flow/exteriorarea as the design flow rate calculation
method. I have also checked the internal gain inputs and they don't seem
to be too high or low. The lighting power is in line with ASHRAE 90.1
requirements, number of people is 0.04 person/m2 and equipment load is
2.7 W/m2.
- Any suggestions?
- Thanks,
