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

The graphic is showing the daylight glare probability (DGP) of a front desk in a building lobby over the course of the day at different times of the year. Reference images for the hours of high DGP are shown to highlight the sources of glare. A comparison of different types of glazing show the impact to DGP at the same time and the ability of glass specification alone to handle the glare conditions.

What type of graphic is this?

Design Variables

Is this part of the ASHRAE-209 cycle?

What tools were used for the simulation analysis?

What tools did you use to create the graphic?

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

It provides a high level summary of glare conditions over the course of the year for the different glazing options while providing a detailed and immersive illustration of the specific glare conditions

Is there anything else you would like to mention?

The analysis was performed to study visual comfort in the building atrium, with special focus on the areas such as the front desk where occupants' positions are more fixed. The initial focus of the analysis was on if different glazing types alone would be sufficient to less DGP in those critical positions.
