Passive Design and Comfort Part 2: Visualizing Thermal Comfort and Energy Reduction

5.2. Passive Design and Comfort Part 2: Visualizing Thermal Comfort and Energy Reduction#

5.2.1. Set Shade geometry#

Right click the ExistingShades sub-layer and select the layer.

5.2.2. Verify Shade Geometry#

Verify that selecting the geometry component linked to the shades highlights the shades in green. Clicking elsewhere in the canvas highlights the shade red. Then, hide the preview for the geometry component.

5.2.4. Add Window Border Shades#

Use a “LB Cumulative Sky Matrix” component. Connect the outputs of ImportEPW component to the respective inputs of SkyMatrix. This models an adjustable border along the perimeter of the windows.

5.2.5. Create Sky Matrix from Imported EPW Data#

Insert a “LB Analysis Period” component and connect to the _hoys output of SkyMatrix. Create two integer-type Number Sliders, one ranging from 1 to 12 and the other from 1 to 31. Connect the former to _start month and _end month inputs to represent the 12 months of the year. Wire the latter to _start day and _end day for the 30 days of the month.

5.2.6. Set Analysis Period for Summer Design Day#

June 21st is chosen as our model summer design day. Create a “LB Incident Radiation” and set the reference values for grid size and offset distance before running the component.

5.2.7. Create Incident Radiation Visualization#

5.2.8. Reference Screenshot: Linking Geometry to the Incident Radiation Block#

Note the geometries are connected all the way back to the IncidentRadiation _geometry input.

5.2.9. Generated Incident Radiation Visualization in Rhino#

This shows how much sunlight hits each part of the model’s surface. Use a perspective view to explore the visualization. What do you notice? need to fix bug that shows part of the roof as not having incident radiation

5.2.10. Create Radiation Dome Visualization#

Using LB Radiation Dome, create a visualization of the solar energy or radiation received by the area from all directions.

5.2.11. Generated Radiation Dome Visualization in Rhino#

This shows the apparent sunlight hitting our location from the sky. Notice it is not exactly symmetrical.
