Common HVAC System types are available to input in the Air Handler and Zone Equipment input screens for TSPR. HVAC Systems may be added by selecting the associated Equipment types, and the Cooling and Heating sources. VRF Condenser Units and Plant Loops that serve HVAC systems should be added before Air Handlers or Zone Equipment.
Generally, all of the supported HVAC Systems as listed in Table D601.11.1 of the 2018 WSEC have been incorporated into the tool and are available to model.
Additional data entry notes for selected systems, including DOAS appear below the table.

* TSPR Data Entry Notes:
VAV with Hot-Water Reheat and VAV with Electric Reheat – For water-cooled chillers, first add a Condenser Plant Loop with a Cooling Tower Plant, then add a Cooling Plant Loop with a Chiller Plant and select the Condenser Loop so the Chiller Plant Loop and Condenser Plant Loop are linked.
Ventilation Only – Available as a selection for Air Handlers, a ventilation only (no cooling, no heating) system may only be assigned to a block with Parking Garage (Ventilation Only) selected as the use type.
Dedicated Outdoor Air System (DOAS) – Available only as a selection from the System Type pull down menu on the Air Handlers screen, the following configurations are supported for DOAS Systems:
| Cooling Source | Heating Source | Distribution Type | Fan Control |
|---|---|---|---|
| No Cooling | No Heating | NA | CAV or VAV |
| No Cooling | Furnace (Gas Fired or Electric Resistance) | Single Zone or Multi Zone | CAV or VAV |
| No Cooling | Plant (Hot Water) | Single Zone or Multi Zone | CAV or VAV |
| DX Cooling | Furnace (Gas Fired or Electric Resistance) | Single Zone or Multi Zone | CAV or VAV |
| DX Cooling | Heat Pump | Single Zone | CAV or VAV |
| Plant (Chilled Water) | Plant (Hot Water) | Single Zone or Multi Zone | CAV or VAV |
Additional entries required for DOAS::
A block is required to have a ‘Primary Heating/Cooling System’ and ventilation can be provided through the DOAS system or through the primary heating/cooling system itself. When a DOAS is assigned to a block, it is categorized as the ventilation system serving the block and the block requires an additional assignment of a Air Handler or a Zone Equipment as the 'Primary Heating/Cooling System' to complete the HVAC System entry.
A DOAS may be combined with
- any Zone Equipment System Type except Baseboard and radiators.
- any Air Handler without plant loops and with single zone distribution and constant volume fan control.
Water-Loop Heat Pump (WLHP) – Available as a selection for Zone Equipment. Follow the steps below to create:
- Add a Condenser Plant Loop
- Select Cooling Tower as the Condenser Plant Type
- Add a Boiler Plant using the ‘Add a Boiler’ button
- Add Zone Equipment and select ‘Water-Loop Heat Pump’ from the HVAC System Type pull down menu
- Note that the Cooling/Heating Source, Fuel Type, and Condenser Type fields are automatically populated
- Select the Cooling Tower Condenser Plant Loop that was created in step one
Ground Source Heat Pump (GSHP) – Available as a selection for Zone Equipment. Follow the steps below to create:
- Add a Condenser Plant Loop
- Select Ground Heat Exchanger as the Condenser Plant Type
- Add Zone Equipment and select ‘Ground Source Heat Pump’ from the HVAC System Type pull down menu
- Note that the Cooling/Heating Source, Fuel Type, and Condenser Type fields will have been automatically populated
- Select the Ground Heat Exchanger Condenser Plant Loop that was created in step one
Variable Refrigerant Flow (VRF) – Available as a selection for Zone Equipment. First add a VRF Condenser Unit, then add a Zone Equipment and select the linked VRF Condenser Unit so that they are linked. VRF Condenser Units may be combined with a DOAS.
