Wind Speed describes airflow for an inflow condition. Pedestrian Wind Comfort combines wind speed and frequency with a comfort criterion. Use the comfort analysis when your question concerns outdoor use over time.
Step 1: Prepare the site
Open your project. In Data layers, check the buildings, trees, ground materials and weather file. Use the same site boundary for each design option. The example in this guide is in central Vienna.
Step 2: Select the comfort criterion
Select Add analysis, then Pedestrian Wind Comfort. Open its configure control in Selected. Under Comfort criterion, choose the criterion for your study. The current list includes Lawson 2001, Lawson LDDC, Lawson 1970, VDI 3787, Davenport and the NEN 8100 comfort and safety options.
The example uses Lawson 2001 (default). Record your choice. Results from different criteria do not have the same class definitions. See the comfort criteria article for background.
Step 3: Check the period and run
Review Weather & period. Use Customize period to choose a preset or set custom months and hours. Our example uses the saved June daytime window. Check the cart price and press Run.
Wait for the run to complete. Open the new result in Results. Keep the criterion, weather and period with the map when you share it.
Step 4: Inspect the places people use
Read the legend and comfort classes. Inspect entrances, corners, pedestrian routes and places for sitting. Use sample pins or draw an area to inspect a location. A comfortable site average can hide a local problem.
Comfort and safety are separate questions. A screening result supports design decisions. It does not certify a site or replace the checks required for your project.
Step 5: Compare design scenarios
Add a scenario for each design option and run the same comfort analysis with the same settings. Open Compare, then Across scenarios. Inspect the map patterns before you use the table or difference mode.
The Hong Kong dashboard below shows a baseline and four variants. Its visible maps are Wind Speed, not pedestrian comfort classes. The same dashboard controls let you compare the completed analyses in your own study. Do not read a speed map as a comfort classification.
