The performance pathway under the Energy and Atmosphere category requires what specific rating?

The correct choice is the HERS Rating, which stands for Home Energy Rating System. This rating is a comprehensive index that reflects a home's energy efficiency by assessing the home’s design and energy use through specific calculations and simulations. The HERS Index score helps to demonstrate compliance with the performance pathway under the Energy and Atmosphere category of LEED.

A HERS Rating can guide builders and homeowners on the energy performance of the house, allowing them to make informed decisions to improve efficiency. It meets LEED criteria by showing that the home achieves a certain level of energy savings compared to a baseline home.

In contrast, while LEED Certification signifies overall adherence to the LEED standards, it does not specify the energy performance metrics required under the performance pathway. The Energy Star Rating indicates energy efficiency but refers to a program rather than a specific compliance measurement under LEED. An Indoor Air Quality Assessment focuses on livability and health aspects of a building rather than directly addressing energy performance. Thus, the HERS Rating is the most relevant and specific requirement for this context.
