Roof Energy Heel

Open this truss s specification dialog check energy heel and force truss rebuild then click ok and use the multiple copy edit tool to replicate the truss as needed.

Roof energy heel.

The extra height of a raised heel truss roof provides additional space for uncompressed attic insulation and the full depth of insulation to be extended right to the outside of the top plate. Standard heel typical truss heel height is about 4. To create a truss with an energy heel a vertical member is added over the supporting wall and the bottom chord stops there rather than extending into the overhang. More importantly the raised heel provides the opportunity to increase energy efficiency to meet new energy code requirements.

Raised heel trusses also known as energy heel trusses deliver cost effective energy performance especially when used with continuous plywood or osb sheathing. There are a couple of options for designing energy heels. To create an energy heel in the build roof dialog check trusses no birdsmouth uncheck automatic birdsmouth cut specify the desired energy heel height as a positive raise off plate value automatically generate or manually draw the roof planes then draw and position the first truss. The option 1 figure to the right shows a raised energy heel.

Truss heel height the vertical depth of the truss at the outside face of the bearing. Design a raised heel. This is created by designing the truss with a heel height tall enough to meet the r value requirements. Raised energy heel typical truss heel height is about 12 but may be designed to most any height per the building designer specification.
