Sefaira for SketchUp: Use Cases

  1. 1. Four Rules of Thumb That Could Lead You Astray Rules of Thumb can point you in the wrong direction. Here’s what you need to know so you don’t get misled.
  2. 2. Sefaira for SketchUp lets you study building performance in realtime, as you design. Here are just a few examples of how you can use it …
  3. 3. 1. Study building form Quickly study the impact of building shape through simple massing studies. Square (lowest energy use) Rectangle Tower (highest energy use)
  4. 4. Sefaira for SketchUp can help you maintain a constant floor area as you change the massing Tip: Maintain a constant glazing amount on each façade to isolate the effects of form
  5. 5. 2. Investigate Heat Gains Is heat gain a problem? If so, which facades are responsible?
  6. 6. Cooling is the largest energy use in this building. Cooling is driven by heat flowing into the building. Solar gain from the West façade is the largest single contributor
  7. 7. Reducing West glazing brings down total energy use significantly Now Heating is the largest energy use
  8. 8. 3. Size Shading Devices Investigate different building and glazing options.
  9. 9. Keep an eye on energy use to see how much shading is beneficial Tip: Inset windows can also be used to shade
  10. 10. 4. Explore Façade Design Just design. Use Sefaira for SketchUp as needed to help size glazing and shading, or to compare options.
  11. 11. You can compare different designs based on energy use Use the energy breakdown and Heat Flows charts as a guide while you design
