3 | | -## Convert IFC to OpenStudio Model |
4 | | -1. In FreeCAD go to the ArchEng Workbench. Make sure you have installed the workbench by following the [getting started guide](02_shoebox.md#install-the-architecture-engineering-workbench) |
5 | | - |
6 | | -2. Click on the ifc2osmod button. Specify your ifc file and where you want to store your osmod file. Then click on 'Convert to osmod'. |
7 | | -```{image} ../_static/shoebox3/shoe3_22.png |

101 | | -## Cooling thermostats schedules |
102 | | -1. Go to the 'Thermal Zones' tab. We only have one zone in this model. The 'Cooling Thermostat Schedule' and 'Heating Thermostat Schedule' are empty. So we need to create a schedule for it. |
103 | | -```{image} ../_static/shoebox3/shoe3_13.png |
| 76 | +7. Congratulations!! You have successfully Model, Simulate and Visualize the shoebox model. Complete the template by varying design parameters like bigger window to wall ratio, thermal resistance and window u-value. So you can see how design parameters change HVAC performance. |

109 | | -2. Go to the 'Schedules' tab. Click on 'Schedules' in the window. Click on the '+' button at the bottom. A window will pop up. At the 'Schedule Type' parameter choose 'Temperature'. There are many temperature schedule, choose the last one that has a lower limit of 0degC and upper limit of 100degC. |

130 | | -5. Hover on the second segment and put in value 25 degC. Hover on the third segment and put in 50 degC. This schedule means the HVAC will cool the space to 25C from 8:00 to 18:00. From 0:00 to 8:00 and 18:00 to 24:00, it will turn on cooling only if the air temperature rise above 50degC, which will not happen. It is essentially setting cooling to not turn on. |
