Choose the comfort criterion, check the weather period and inspect the completed Vienna result.

**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

The Vienna site and its loaded inputs

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](https://infrared.city/knowledge-base/pedestrian-wind-comfort-criterias) 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.
