Fractal Zooming Tutorial

Loading video please wait.

Creating large layouts to represent an entire organisation can lead to poor system performance.  To assist with this problem Eco3D includes Fractal Zooming.  This allows for multiple small layouts to be brought together to get overall statistics and reports.

From the Eco3D Main Menu click Fractal Zooming.

To start click the Add button.  You will then be prompted for a file name and location for this new Fractal Zoom. Click Save after entering the file name.

You will then be presented with the “Layout Details” dialog.  Enter the name for the top level of the Fractal Zoom. In the video we enter “example”, but this can be your organisation name, or some other identifier for the top level you are investigating. By leaving the “Layout File” blank the layout will automatically be generated using information from the sub layouts. Click ok to create the top level.

Next add the first sub node by selecting the top node and clicking the Add button; in the video it is called “Manchester”.   This node will sum the consumption of activities in Manchester. Again leave the “Layout File” blank.

Continue adding sub nodes to build your corporate Tree structure.  In the video nodes called “office” and “call centre” are added.  For each of these nodes an existing layout file is selected.

Next in the video a second branch is added by selecting the top node and clicking add.  This node is called “Leeds”.  Within Leeds a node called “accounts” is added and an existing layout selected.  This completes our example structure.

When Run is clicked the fractal zoom will start generating the total carbon footprint for the company. 

The process starts by simulating all the bottom level nodes, in the video these are office, call centre and accounts.  Three different instances of Eco3D Pro load the layouts and run the simulation. Once all three layouts have been simulated the data is collected. All three Eco3D Pro instances then close.

The next level of the fractal tree is then simulated. Two instances of Eco3D Pro open, one for Manchester and one for Leeds. As no layouts were selected for these nodes, the Manchester and Leeds layouts are automatically built. When building the Leeds layout all the consumption data from all the components are summed and feed into one component, represented as a green cylinder. This one component now has the same consumption as the whole accounts layout. In the Manchester layout there are two green cylinder components one represents the office layout and the other represents the call centre layout. Once the layouts have been simulated the data is collected and the two instances of Eco3D Pro close.

The top level of the fractal tree (example) is now simulated. As no layout file was specified the layout is automatically built. There are two green cylinder components (the two components are on top of each other) One component represents all the consumption of Manchester and the other represents the consumption of Leeds.

Once the Fractal Zoom is complete, select the top level node of the tree and click the Report button.  This will generate the PDF report.
