Ecotect Tutorial: Display Analysis Grid Solar Radiation Values

Synopsis

This ECOTECT tutorial explains how to display solar radiation values shown on the analysis grid if they already exist in an ECOTECT model.

Duration

You will need about 10 minutes to complete this tutorial.

Training and Accreditation

Successfully completing this tutorial fulfills one of the practical skills required for completing Level 1 of the Solar Radiation Analysis training module.

Resources Required

To complete this tutorial, open the FacadeSlab-InsolationGrid.eco file located in the Examples folder of your ECOTECT installation.

Tutorial

  1. Press F9 to switch the model to a perspective view. The example file consists of a partial sectional model through the facade of a building. This kind of model is used to test and analyse the solar performance of the proposed shading system. You can also see that an analysis grid has been set up in line with the facade glazing, and that some initial solar radiation calculations have been performed.

  2. Click on the Visualise tab to get a clearer view of the model. Then go to the Analysis Grid tab. Under the Grid Data_Scale section, the drop down box allows you to control what solar radiation data is displayed on the the analysis grid. The analysis grid display automatically updates as you cycle through the data options.

  3. Below the data options, you can adjust the minimum and maximum display ranges for the analysis grid, along with the contour band spacing. Generally, it's not necessary to alter these values manually, as ECOTECT will usually determine the most appropriate values based on the range of data being displayed.
  4. Click the button next to the Contours field. In the context menu that appears, select the Customise Scale... option. In the dialogue box that appears you can customise the colours used for the analysis grid display. Click Ok when done.

  5. Go back to the 3D Editor tab. Under the Grid Settings section of the Analysis Grid tab, check the Show Node Values option - this superimposes the data values over the analysis grid (zoom in the see the values more clearly). You can also limit the node value display with the Peaks & Troughs and Selected Only sub-options.
    Node values can also be shown superimposed over the analysis grid.

  6. To display only selected node values on the analysis grid display, you need to use the Grid Nodes section of the Analysis Grid panel to set a threshold range of node values to display. Click the button, and click on the Select nodes above threshold context menu option.
  7. A dialogue box appears prompting you to specify the threshold value - choose a number between the minimum and maximum range values for the grid data currently being displayed. Click the Select grid nodes button, and the analysis grid colour display is temporarily turned off, and the nodes that meet the threshold criteria are highlighted in red.

  8. The Hide and Show buttons allow you to control the visibility of the selected nodes of the analysis grid. Click the Select Grid Nodes button again to turn the analysis grid colour back on. Use the Selected Only checkbox sub-option mentioned above to show the data values for just these nodes.
    You can turn off parts of the analysis grid using the Hide button.
