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

The graph shows the potential energy savings between different design schemes. Scheme 1, acting as a baseline or control, includes a standard single roof systems, whereas scheme 2 includes a double roof system. Scheme 3 depicts a double roof system, with 4'-0" overhangs on each sides. Lastly, scheme 4 includes a double roof system with 4'-0" overhangs and natural ventilation. The annotated section at the bottom shows how the systems are integrated.

What type of graphic is this?

  • Diagram
