Which of the following is a benefit of an Energy Heel truss?

An Energy Heel truss is specifically designed to enhance the insulation performance of the roof assembly, particularly at the eaves and corners of a building. This design allows for a thicker layer of insulation to be placed at the edges where heat loss is typically greatest, which leads to improved energy efficiency. The unique shape of the Energy Heel truss provides the necessary height to accommodate insulation that extends all the way to the exterior walls, minimizing thermal bridging and enhancing overall energy performance.

By focusing on reducing energy loss at critical junctions like corners, the Energy Heel truss helps maintain stable indoor temperatures, making buildings more comfortable and energy-efficient over time. This is particularly beneficial in climates with extreme weather, where insulation plays a crucial role in energy savings.

The other options, while they might have some connection to truss or framing systems, do not specifically highlight the primary advantage of an Energy Heel truss, which is its focus on enhancing energy efficiency. Thus, option C stands out as the most relevant benefit.
