TheLEED for Homes Rating System (v4)integrates ENERGY STAR Homes certification as part of theEnergy and Atmosphere (EA)category, specifically for theEA Prerequisite: Minimum Energy PerformanceandEA Credit: Annual Energy Use. ENERGY STAR Homes certification requires energy simulation software to model the home’s performance, and this software must be approved by a specific authority.
According to theLEED Reference Guide for Homes Design and Construction (v4):
EA Prerequisite: Minimum Energy Performance
Projects pursuing ENERGY STAR for Homes certification must use energy simulation software accredited by the Residential Energy Services Network (RESNET) to demonstrate compliance with ENERGY STAR performance requirements.

TheResidential Energy Services Network (RESNET)is the organization responsible for accrediting energy modeling software used for ENERGY STAR Homes certification, such as REM/Rate or Ekotrope. RESNET establishes standards for Home Energy Rating Systems (HERS) and ensures software accuracy for energy performance calculations.
TheLEED v4.1 Residential BD+Crating system aligns with this:
EA Prerequisite: Energy Performance
ENERGY STAR Homes certification requires the use of RESNET-accredited energy modeling tools to verify performance targets, such as HERS index scores.

While theEnvironmental Protection Agency (EPA)oversees the ENERGY STAR program, it does not directly approve the simulation software; that responsibility lies with RESNET.
Why not the other options?
