Goals

  1. Learn how to quickly perform daylighting studies and generate graphics for presentations. 
  2. Understand how other firms are using Sefaira Daylighting tools to enhance their projects. 

Daylighting visualization allows designers to make better decisions around glazing, shading and facade design. Powerful visuals help communicate a design’s performance and the experience within a space during design discussions and client presentations.

Before you get started.. 

Sefaira’s Daylighting Visualization is integrated in the SketchUp and Revit plugins. If you don’t have one of the plugins installed yet, please click here to get started. If you don’t have a model handy, you can use one of our sample models for SketchUp or Revit.

How to create Customizable Daylighting Graphics

Sefaira’s daylighting visualization allows you to rapidly analyze a design in four different daylighting metrics and export your results using three different style options.  

Time-of-day visualizations are useful for understanding the experience in a space at a given point in time (1).  Different color palettes allow you to customize graphics for any type of output to match your presentation style, including a grey-scale option that can easily be converted to any color palette using a photo editor (2). 

Annual daylighting metrics summarize the daylighting performance of your building throughout an entire year, taking into account design, location, and weather (3).  For better graphics, you can also choose between three different rendering styles when you communicate your design intent: gradient, grid or contour (4). 

Sefaira provides visualizations of overlit & underlit spaces to help you understand which sections of your design need more light or experience glare (5). And while Sefaira daylighting visualization runs in real-time and directly within SketchUp and Revit, remember that you can export high-quality graphics for your presentations by either taking a snapshot with the camera button, or by exporting individual floor plans (6).  Sefaira also helps to keep Spatial Daylight Autonomy (sDS)  and Annual Sunlight Exposure (ASE) on track by aligning with LEEDv4 daylighting credits (7). You can see these metrics on a per room basis or for the entire selected floor.  LEED points can be earned with minimum sDA levels of 55%, 75%, and 90% and maximum ASE is 10%. 

Daylight factor is an annual simulation of the daylight ratio under overcast sky conditions, providing the “worst case scenario” of a design (8). Sefaira provides three overall daylight factor metrics for the analysis area: Average Daylight Factor, Minimum Daylight Factor, and Uniformity Ratio. The last style option allows you to add context elements like walls, roofs, glazing, and shading to provide visual context as you design (9).

Sefaira Direct Sunlight visualization provides analysis for a set day or over a variable time range(10), read more about Direct Sunlight here.  The results can be reported on a room by room basis (11).

The daylighting settings can be adjusted between footcandles and lux, as well as the number of ambient bounces. A lower number of ambient bounces produce faster results, while higher bounces produce more accurate results.

    We were able to demonstrate that these proposals provided a much better daylighting balance than the existing building does in its current form. Our client was very happy with the finished report which they felt gave them the right information to help guide decision making.

    Integrating all aspects of a project is critical to our design process. This includes the planning of space that is flexible and hyper-utilized, the aesthetics of the form and space, the performance and sustainable effectiveness of systems, as well as the learning opportunities afforded by the integration of all of these items. From an architectural standpoint, Sefaira provides the quick tools we need as designers to analyse and communicate our design and its performance.
