Audience:

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

The graphic shows the building energy by end use in order to direct future analysis to target load reduction strategies. Additionally, the building sensitivity to various envelope performance options highlight which design elements can successfully influence the greatest impact on overall building performance.

What type of graphic is this?

  • Case Study / Multiple
  • Analysis grid

Design Variables

  • Glass U-value / SHGC
  • Glazing Fraction/Window to Wall ratio
  • Insulation R-value

Is this part of the ASHRAE-209 cycle?

  • Cycle 1 Simple Box Model

What tools were used for the simulation analysis?

  • Excel
  • IES-VE

What tools did you use to create the graphic?

  • Excel
  • PowerPoint

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

The graphic allows all sensitivity analysis to be compared to a single performance scenario. Similar scales allow the visual differences between analyzed options to emphasize the difference in energy performance. Because the intersection of the two analyzed design parameters forms a virtual surface, the glazing performance graphics allow for other assembly options to be estimated and analyzed.

Is there anything else you would like to mention?
