Synchronizing analysis views for multiple proposals

Step-by-step guide

Multiple analyses for different designs can be viewed side by side, to examine the trade-offs of each and make data-based decisions regarding the best design alternative.

In this example of a residential site located next to a railway in Oslo, Norway, two important considerations are sun exposure and noise. The relevant analyses have been run.

1. In the top bar, click Compare.
2. In the left panel, under the relevant proposals, select the desired analyses. In this example, select the Noise analyses for the Alternative 2 and Alternative 4 proposals.

3. To make room for the second analysis, on the canvas, right-click each analysis and select Split horizontally.

4. Drag the Sun hours analysis for the Alternative 2 and Alternative 4 proposals, and drop them into the respective view panes.

5. Optionally, to replace one of the analyses, drag and drop another analysis into the desired view pane.
6. Pan and zoom the four synchronized camera views to examine the results.

Looking at Alternative 2 for Sun hours on April 21st, the summary shows that 10,281 square meters, or 36% of the site, has more than 9 hours of sun on the ground.

Alternative 4 has more than 16,500 square meters, or 52% of sun, over 9 hours—a significant difference that may help with the decision to use one design option over the other.

7. Expand the summaries for the noise analyses.
8. Scroll down to see the results for Ground, Facades, and Roofs.
9. When Facades is selected for both alternatives, Forma reports that 72% of Alternative 2 is in green, which is a comfortable noise level, whereas 69% is in green for Alternative 4.

10. To expand the view area, click the arrow on the edge of the summary panel to hide it.

Overall, Alternative 2 is better for noise than Alternative 4, but it does not offer as much sun exposure, whereas Alternative 2 offers better sun exposure, but is not as good for noise.
