After making a selection, review the Heating and  Cooling sources that were automatically populated. Create and link Plant Loops as needed and prompted for certain system types. Refer to the HVAC System Types section for a table of suggested  configurations, and guidance regarding System Type selections.

 

Cooling Source– Pull-down menu selections. Select your installed cooling equipment type  from  the following:

 

No Cooling – If no mechanical cooling equipment is installed

 

Terminal DX – Included as part of Packaged terminal air-conditioner (PTAC); Packaged terminal heat pump  (PTHP);  and Window Air Conditioners.

 

Plant – Select this type if a Plant Cooling Loop was previously entered. The  type of Plant (Chiller or District) will be available to select under the Plant Loop field.

 

Heating Source– Pull-down menu selections. Select your installed heating equipment type  from  the following:

 

No Heating – If no mechanical heating equipment is installed.

 

Single Zone Central Furnace – Natural gas, fuel oil, or propane-fired or electric resistance furnace.

Plant – Select this source if a Plant Heating Loop was previously entered. The  type of Plant  (Boiler or District) will be available to select under the Plant Loop field.


Convective Baseboard: Electric – Select this source as a Secondary Heating and Cooling System. May be added to a block after either a Window Air Conditioner, Packaged Terminal Air Conditioner, or Four Pipe Fan Coil Unit system has been created and assigned.


Convective Baseboard: Hot Water – Select this source as a Secondary Heating and Cooling System. May be added to a block after either a Window Air Conditioner, Packaged Terminal Air Conditioner, or Four Pipe Fan Coil Unit system has been created and assigned. A Heating Plant Loop must be created and linked to this selection.
