Calculating building electrical loads
You will learn how to calculate preliminary electrical loads early in the design process.

Estimated time to complete topic:
15 minutes
Topic steps:
12
1. On the Analyze ribbon, in the Electrical Analysis panel, click Area Based Load Boundary.
2. In the Properties palette, set the Top Level to SECOND FLOOR and the Bottom Level to GROUND FLOOR.
3. In the Draw gallery, use the available sketch tools to create boundaries around the different room types in the building, such as exam rooms, offices, lobby and so on. Press ESC to end the command after creating the boundaries.
4. On the Analyze ribbon, in the Electrical Analysis panel, click Area Based Load.
5. With Add Load Area selected in the contextual ribbon, select a load boundary in the drawing area.
6. Click Finish Editing after the desired loud boundaries have been selected.
7. Select an electrical analytical load in the drawing area.
8. In the Properties palette, click in the Area Based Load Type field and click the More button.
9. In the Electrical Analytical Load Type Settings dialog, select General Lighting and then specify the Electrical – Loads parameters to define the lighting loads of the selected boundary.
10. Open the System Browser to define the conceptual distribution system. To open the System Browser, on the View ribbon, in the Windows panel, expand the User Interface button and select System Browser.
11. Use the tools in the System Browser – Analytical Power Distribution to define the conceptual distribution system.
12. Select an area-based load in the System Browser. The instance properties of the load will populate in the Properties palette. Specify the Name, Supply From, and additional parameters as needed to define the analytical electrical system.
