What tools did you use to create the graphic?
What kind of graphic is this? bar chart
Primary Inputs: Design elements
Primary Outputs: Energy cost
What are we looking at?
These graphs show the impact of design elements added incrementally to an ASHRAE Standard 90.1-2007 baseline design, which is shown at the top.
The left graph shows annual energy cost, and the right graph displays percent energy cost savings vs. the ASHRAE baseline.
The graphic shows the designers the relative magnitude of savings contribution by design elements. The information helps when prioritizing where to focus effort in design development.
How did you make the graphic?
The graphs are created in Excel, and they are combined and annotated in PowerPoint.
What specific investigation questions led to the production of this graphic?
How many LEED EAc1 points are achieved by the schematic design?
Which elements of the schematic design contribute most to the energy savings?
How does this graphic fit into the larger design investigations and what did you learn from producing the graphic?
Prior to the analysis represented in this graphic, the design team spent significant effort identifying options for additional wall and roof insulation for this project in central California. This analysis helped focus efforts on lighting and daylighting and on kitchen ventilation.
What was successful and/or unique about the graphic in how it communicates information?
Showing design elements added incrementally helps to show a path to a savings goal.
What would you have done differently with the graphic if you had more time/fee?
Could figure out a way to also present end-use energy consumption while remaining readable.
