What is the impact of WWR on Sensible Cooling Load and Energy Use?

Project Location: Zone 0A Extremely Hot Humid

Simulation Scale: Whole Building

Application: Conceptual

Audience: Academic

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

The graphics illustrate the percentage increase in the Sensible Cooling Loads and Energy Consumption in the office building when only the Window Wall Ratio (WWR) is increased, while the U-value and the SHGC of the glazing are kept constant for each iteration.

What type of graphic is this?

  • Diagram

Design Variables

  • Glazing Fraction/Window to Wall ratio

Is this part of the ASHRAE-209 cycle?

What tools were used for the simulation analysis?

  • Design Builder
  • EnergyPlus
  • Excel

What tools did you use to create the graphic?

  • Adobe Photoshop

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

The graphic comprises bars demonstrating the percentage rise in Sensible Cooling Loads and Energy Consumption as the Window-to-Wall Ratio (WWR) is increased.

Is there anything else you would like to mention?
