This is the key part of the error:

Object=ZONEINFILTRATION:DESIGNFLOWRATE, name=189.1-2009 - OFFICE - WHOLEBUILDING - LG OFFICE - CZ1-3 INFILTRATION 3 * ~~~ * Field [Schedule Name] is required but was blank

Which means you have an infiltration object with no schedule. There are 2 ways to set the infiltration schedule.

1. Set it on the infiltration object directly

1. Set the infiltration schedule in the schedule set that covers the space type in question. In your case, it looks like it would be the schedule set for the space type 189.1-2009 - OFFICE - WHOLEBUILDING - LG OFFICE The infiltration schedule that is set here will cover all the infiltration objects in all of the spaces of this space type.
