In general, any Fatal messages are indicating what causes your simulation to fail. From your error file messages:

* Warning * Could not find chilled water coil with name SYSFANPWRVAV_SYS 1 COOLING COIL on any plant loop * ~~~ * Autosizing of water coil requires a cooling loop Sizing:Plant object * ~~~ * Occurs in water coil object= SYSFANPWRVAV_SYS 1 COOLING COIL * Fatal * Preceding water coil sizing errors cause program termination

So, the Fatal message is saying that a water coil sizing error in the preceding lines above is causing EnergyPlus to stop the simulation. The preceding lines say that a chilled water coil named SYSFANPWRVAV_SYS 1 COOLING COIL is defined in the model, but it is not connected to any plant loop (term EnergyPlus uses for a liquid loop like hot water plant or chilled water plant).

This issue is repeated in two of the Severe error messages in your error file:

* Severe * Node Connection Error, Node="SYSFANPWRVAV_SYS 1 COOLING COIL CHW INLET", Inlet node did not find an appropriate matching "outlet" node. * ~~~ * If this is an outdoor air inlet node, it must be listed in an OutdoorAir:Node or OutdoorAir:NodeList object. * ~~~ * Reference Object=BRANCH, Name=SYSFANPWRVAV_SYS 1 COOLING COIL CHW BRANCH * Severe * Node Connection Error, Node="SYSFANPWRVAV_SYS 1 COOLING COIL CHW INLET", Inlet node did not find an appropriate matching "outlet" node. * ~~~ * If this is an outdoor air inlet node, it must be listed in an OutdoorAir:Node or OutdoorAir:NodeList object. * ~~~ * Reference Object=COIL:COOLING:WATER, Name=SYSFANPWRVAV_SYS 1 COOLING COIL

EnergyPlus connects HVAC components together through Inlet Node Name and Outlet Node Name input fields. You have defined your cooling coil object with an Inlet Node Name set to SYSFANPWRVAV_SYS 1 COOLING COIL CHW INLET, and somewhere else in the model another HVAC component object should have it's Outlet Node Name also set to SYSFANPWRVAV_SYS 1 COOLING COIL CHW INLET. This tells EnergyPlus where the water entering the chilled water coil comes from.

It looks like you have a similar issue with a hot water coil as well:

* Severe * Node Connection Error, Node="SYSFANPWRVAV_SYS 1 HEATING COIL HW INLET", Inlet node did not find an appropriate matching "outlet" node. * ~~~ * If this is an outdoor air inlet node, it must be listed in an OutdoorAir:Node or OutdoorAir:NodeList object. * ~~~ * Reference Object=BRANCH, Name=SYSFANPWRVAV_SYS 1 HEATING COIL HW BRANCH * Severe * Node Connection Error, Node="SYSFANPWRVAV_SYS 1 HEATING COIL HW INLET", Inlet node did not find an appropriate matching "outlet" node. * ~~~ * If this is an outdoor air inlet node, it must be listed in an OutdoorAir:Node or OutdoorAir:NodeList object. * ~~~ * Reference Object=COIL:HEATING:WATER, Name=SYSFANPWRVAV_SYS 1 HEATING COIL

If you used an interface to create your model, make sure that these chilled water and hot water coils are properly connected to their respective plant loops. This post also offers some tips on addressing node connection issues for plant loop HVAC components.
