Summary of "DesignBuilder tutorial: Construction, people & lighting"

Main Ideas and Concepts

Construction Creation in DesignBuilder:
The tutorial focuses on creating construction materials and their properties within a building model in DesignBuilder. The initial setup involves a predefined building block (15m x 15m) with different materials assigned to various surfaces.
material editing and Inheritance:
Users can create new materials by modifying existing ones, with a key point being that changes in one material category will affect all instances of that material across the building. To change specific materials for different walls, users must select and edit those individual walls.
Layer Management:
Materials can consist of multiple layers (e.g., brick, mortar), and users can customize the number and type of layers according to their design needs. The process includes copying existing materials to create modified versions.
internal gains from Occupants:
The tutorial discusses how to manage internal gains from people, equipment, and lighting within a building. Occupancy levels are determined based on the number of people per square meter and their activity schedules.
Scheduling Occupancy:
Users can create occupancy schedules that reflect the presence of people throughout the week and during different seasons. Schedules can be edited to reflect varying occupancy levels, such as in offices or gyms.
activity levels and Metabolism:
Different activities (e.g., reading, typing) have associated metabolic rates that affect energy gain calculations. Users can set parameters for density and activity type to simulate realistic internal gains.
lighting management:
Lighting data can be incorporated into the model, including normalized power density and scheduling. Users can set lighting levels based on guidelines and adjust parameters for detailed analysis.

Methodology/Instructions

Creating and Modifying Materials:
- Select the wall section and create a new material.
- Copy an existing material to modify it.
- Change the name and adjust the number of layers (e.g., from four to two).
- Edit layer properties, including material type and thickness.
Managing Occupancy and internal gains:
- Access the activity level to set occupancy levels.
- Create or edit schedules for different occupancy types (e.g., office, gym).
- Adjust the schedule to reflect the number of people present at different times.
Adjusting Lighting Parameters:
- Input lighting data into the model.
- Create lighting schedules similar to occupancy schedules.
- Change normalized power density settings as required.
