# Assign Program Types

A program type is useful for energy simulations. It helps to organize and edit energy model more easily and flexible for a complex project.

## **Step 1**

Use command [PO\_EditRoomProperties](/user-manual/rhino-plugin/pollination-commands/alphabetically/po_editroomproperties.md) or double click the room from "Room Manager" to bring up the "Room Properties" dialog, in which you can override room's program type.

## **Step 2A**

Select a program type from "Program Type Manager" dialog.

*Note: at the beginning, you may not have all program types that are listed in below screenshot, please check the next **step 2B** to import new program types from OpenStudio Standards templates.*

## **Step 2B**

Import a new program type from OpenStudio Standards template.

*Note:* [*OpenStudio Standards*](https://github.com/NREL/openstudio-standards/) *are developed by the US.* [*National Renewable Energy Laboratory*](https://www.nrel.gov) *(NREL)'s OpenStudio Team. It includes ASHRAE 90.1 baseline model's program types and HVAC system templates. We convert them to* [*Honeybee Schema*](https://www.ladybug.tools/honeybee-schema/model.html) *standard format so it becomes one of the trusted data sources that we can use across our entire eco-system.*
