The Site Shadow Casting Simulation tool dynamically visualizes how a building's shadow changes based on building height, position, and real-time sun angle adjustments. It helps architects, urban planners, and engineers optimize building placement and design by analyzing potential shadow impacts on a site. Users input building and sunlight parameters to instantly simulate shadow length and direction for effective site planning.
How to use this tool?
Complete Guide: Site Shadow Casting Simulation Tool
-
Understanding the User Interface:
- Building Height (m): Enter the height of your building in meters.
- Building X (px), Building Y (px): Adjust the horizontal (X) and vertical (Y) position of the building on the simulation canvas in pixels.
- Sun Elevation (deg): Use the slider to select the sun's elevation angle (height of the sun above the ground/skyline) in degrees.
- Sun Azimuth (deg): Use the slider to rotate the sun's position around the building. Azimuth defines the sun's compass direction.
- Reset Button: Click to return all values to their default settings.
-
Setting Simulation Parameters:
- Input the Building Height to simulate different building elevations and observe the effect on shadow length and direction.
- Adjust Building X and Y values to position the building anywhere on the site diagram.
- Modify Sun Elevation using the slider. Lower angles (morning/evening) yield longer shadows, higher angles (noon) create shorter shadows.
- Change the Sun Azimuth slider to see how the shadow's direction rotates around the building based on compass orientation.
-
Interpreting the Visualization:
- The red square represents your building.
- The yellow circle is the sun's current position.
- The shadow appears as a translucent gray rectangle extending from the building, showing the shadow cast based on current sun conditions.
- The shadow length is calculated and displayed in pixels. Longer shadows indicate lower sun elevations.
-
Experimenting and Resetting:
- Try different building positions and sun angles to study how site layout and time/season might influence shadowing for your project.
- Click Reset to quickly start over or compare multiple scenarios.
-
Applications:
- Use the tool to optimize building placement, identify potential overshadowing issues, plan for solar access, or evaluate seasonal solar paths.
