If you don't know yet how to prepare the BIM model for the Energy Evaluation, take a look at the checklist here. |
Before running an energy evaluation of your project file, Thermal Blocks must be created. All Thermal Blocks have an assigned Operation Profile and Building Systems. For information on creating an Operation Profile, please click here. For information on Building Systems, please click here.
Thermal Blocks are the thermal units of the project. We group zones of the project in Thermal Blocks. These groups of zones share similar thermal characteristics. They are:
Please keep in mind that the more thermal blocks you have, the more time it takes to run the calculation. As a general rule, try not to exceed more than 12-15 thermal blocks.
Follow the steps below to create Thermal Blocks:
1. Go to Design > Energy Evaluation > Energy Model Review to open the Energy Model Review palette.
2. In the Thermal Blocks tab, create your thermal blocks by clicking the Add new Thermal Block button.
3. Give the Thermal Block a distinct ID and name.
4. Assign the Zones to the Thermal Blocks by clicking on the Add Zone to selected Thermal Block button.
At this point you are done with creating the Thermal Blocks. To be able to run the energy simulation all Thermal Blocks have to have an Operation Profile and Building Systems assigned. The next steps lead you through this.
5. Choose an Operation Profile for each Thermal Block.
6. Click the Add new Building System button to open the Add Building System Palette.
7. In the Add Building System palette, select the building system(s) that correspond to the thermal block and click OK.
Later on, as your project evolves, you might need to add new Thermal Blocks, or remove one of them and rearrange the zones in the Thermal Blocks. You can adjust the number and arrangement of the Thermal Blocks at any time. You just have to update the energy model each time by using the Update Energy Model Review command on the Energy Model Review palette.
