What is the impact of various shading strategies on the amount of glare experienced?

Project Location:

Simulation Scale:



What is this graphic showing? Describe the different parts of the graphic and how it communicates the data.

One study shows the likelihood of glare on any particular area of glass during daylight hours throughout the year and the other demonstrates what percentage of space is experiencing glare everyday throughout the year. Precedent images were also provided for context. We also provided an explanatory graphic on the top left to demonstrate why we we feel it's important to show that there are two different opportunities for glare to originate. Our goal is that someone unfamiliar with the project should be able to look at this page and understand it without much prior understanding of daylight and glare.

What type of graphic is this?

  • Case Study / Multiple

Design Variables

  • Window shading/sun control

Is this part of the ASHRAE-209 cycle?

What tools were used for the simulation analysis?

  • Ladybug Tools

What tools did you use to create the graphic?

  • Other

What was successful and/or unique about the graphic in how it communicates information?

I find it most effective to show a set of analyses next to each other to enable viewers to compare results and contextualize their understanding of a project. Additionally, the architects explicitly asked for precedent images as some shading strategies were unfamiliar to them, so the precedent images help familiarize the design team with the recommendations we're making.

Is there anything else you would like to mention?
