Honeybee 'RADIANCE' Part 5 | Dynamic Shading, Context and Schedules | Ladybug tools 1.3.0

Introduction

In this tutorial, we will explore how to incorporate dynamic shading, context, and scheduling into your models using Honeybee and Ladybug tools. This is particularly useful for simulating environmental factors, such as how nearby buildings or seasonal changes affect light and shading on your structures. We will guide you through these processes step-by-step to enhance the realism and functionality of your designs.

Step 1: Setting Up Your Environment

• Start by ensuring you have Honeybee and Ladybug tools installed in Rhino and Grasshopper.
• Open a new Grasshopper document and create a base geometry for your building.
• Import any contextual elements, such as adjacent towers or trees, which will impact your shading analysis.

Step 2: Adding Dynamic Shading

• Use the Honeybee components to create shading devices. Consider the following:

  • Select Shading Type: Decide on the type of shade (e.g., horizontal overhangs, vertical fins).
  • Adjust Parameters: Set parameters for the shading devices such as depth and angle to optimize performance.

• Use the Dynamic Shading component to control transparency based on time or environmental changes.

  • Connect the time or weather data inputs to the shading control parameters.

Step 3: Incorporating Contextual Elements

• To add context to your model, use the Context components in Honeybee:

  • Input Building Geometry: Use the geometry of surrounding structures that might cast shadows.
  • Tree Geometry: If using trees, create them with seasonal variations (e.g., leafless in winter).

• Ensure that the context elements are properly aligned with your building model to provide accurate shading simulations.

Step 4: Scheduling Dynamic Shading

• Implement a scheduling system for your shading devices:

  • Create a time-based input using the Timer component in Grasshopper.
  • Connect it to the shading control parameters, allowing the shading to adjust dynamically throughout the day or seasons.

• Use the Honeybee Schedule component to define when certain shading devices should be active or inactive.

  • Set different schedules for summer and winter seasons to reflect changes in shading needs.

Step 5: Running the Simulation

• With all components set up, run the simulation to analyze the effects of dynamic shading in your model.
• Use the Ladybug Sunpath component to visualize sun movements and assess shading effectiveness at different times of the year.

Conclusion

By following these steps, you can effectively incorporate dynamic shading, context, and scheduling into your architectural models using Honeybee and Ladybug tools. This not only improves the realism of your simulations but also enhances the energy efficiency of your designs. As a next step, consider experimenting with different shading designs and contextual scenarios to see how they impact your model’s performance.
