Hello All,

I'm simulating in designbuilder V3 (detailed hvac) a building in order to
fulfill leed requirements.

I am getting now following warnings:

** Warning ** Coil:Cooling:DX:SingleSpeed "CL-BS-P0 AHU UNITARY COOLING
COIL DX
COOLING COIL" - Air volume flow rate per watt of rated total cooling
capacity is
out of range at 2.283E-005 m3/s/W.
** ~~~ ** Environment=ICTA, at Simulation time=01/01 00:00 - 00:30
** ~~~ ** Expected range for
VolumeFlowPerRatedTotalCapacity=[2.684E-005--6.713E-005]
** ~~~ ** Possible causes include inconsistent air flow rates in system
components,
** ~~~ ** or variable air volume [VAV] system using incorrect coil type.

....and then....

** Warning ** Coil:Cooling:DX:SingleSpeed "CL-BS-P0 AHU UNITARY COOLING
COIL DX
COOLING COIL" - Full load outlet air dry-bulb temperature < 2C. This
indicates
the possibility of coil frost/freeze. Outlet temperature = -10.33 C.

These warnings refer to Baseline Systems, which I have defined using
directly
the DesignBuilder HVAC template ASHRAE 90.1, System No. 6, leaving
everything as
defined by default, including AHU airflows.

Any idea on how to solve this problem would be really appreciated,
