What is the impact of building envelope component on heat gain?

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 graphic depicts yearly heat gains, illustrating a relationship between declining U-values and decreased heat gains across building components: walls, roofs, and fenestrations. Heat gain arises from factors such as solar radiation, insulation quality, and material properties. As U-values decrease, indicating enhanced insulation, heat gains diminish across these elements.

What type of graphic is this?

  • Diagram
  • Table / Chart

Design Variables

  • Building Materials
  • Glass U-value / SHGC

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 effectively demonstrates the correlation between decreasing U-values and reduced heat gain. It also indicates the building component with the highest heat gain and the percentage reduction in heat gain associated with decreasing parameters such as the U-value of the wall, roof, and window glazing, as well as SHGC (Solar Heat Gain Coefficient) and SRI (Solar Reflectance Index) of roof.
