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

This data compared performance analysis of a vernacular architectural passive element, namely rowshan (mashrabiya), in an arid climate to determine the natural ventilation potential, provide thermal comfort, and reduce energy consumption by minimizing active cooling systems usage in new houses.

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?

The significant finding to the rowshan performance shows that the smaller inlets have led to better indoor ventilation. The CFD results also show that a rowshan can lower daytime peak air temperature in some cases by almost 8°C (14°F).
