TheLEED for Homes Rating System (v4)integrates theHome Energy Rating System (HERS) Indexin theEnergy and Atmosphere (EA) Prerequisite: Minimum Energy PerformanceandEA Credit: Annual Energy Useto measure a home’s energy efficiency.
According to theLEED Reference Guide for Homes Design and Construction (v4):
EA Prerequisite: Minimum Energy Performance
The Home Energy Rating System (HERS) Index, developed by the Residential Energy Services Network (RESNET), is used to assess a home’s energy efficiency compared to a reference home. A lower HERS Index indicates better energy performance.

TheLEED v4.1 Residential BD+Crating system confirms:
EA Prerequisite: Energy Performance
The HERS Index, created by RESNET, is the standard metric for energy efficiency in LEED for Homes, used to verify compliance with ENERGY STAR and LEED requirements.

The correct answer isResidential Energy Services Network (RESNET)(Option D), as RESNET developed the HERS Index.
Why not the other options?
