What Is ENERGY STAR Certification?

ENERGY STAR certification is a national recognition program administered by the U.S. Environmental Protection Agency (EPA) that identifies buildings with superior energy performance.

To earn certification, a building must:

  • Achieve an ENERGY STAR score of 75 or higher

  • Demonstrate high energy efficiency compared to similar buildings

  • Verify building performance through a licensed professional engineer or registered architect

  • Submit certification documentation through ENERGY STAR Portfolio Manager

Buildings that earn ENERGY STAR certification are officially recognized as top-performing energy-efficient buildings.

Benefits of ENERGY STAR Certification

ENERGY STAR certification offers several operational, financial, and reputational benefits for building owners.

ENERGY STAR Portfolio Manager and Certification

ENERGY STAR certification relies on the ENERGY STAR Portfolio Manager platform, the EPA’s official benchmarking tool used to measure building energy performance.

Portfolio Manager calculates a building’s ENERGY STAR score, which ranges from 1 to 100 and compares building performance with similar buildings nationwide.

Buildings must maintain accurate energy data within Portfolio Manager to qualify for certification.

Key metrics calculated in Portfolio Manager include:

  • Energy Use Intensity (EUI)

  • Source energy consumption

  • Greenhouse gas emissions

  • Weather-normalized energy performance

Our ENERGY STAR Certification Process

1. Energy Benchmarking

We benchmark your building using ENERGY STAR Portfolio Manager and verify that all required building information and energy data are accurate.

2. Data Validation

Our team reviews energy consumption data and performs quality checks to ensure the building qualifies for certification.

3. ENERGY STAR Score Evaluation

We analyze your building’s performance metrics and determine whether the building meets the required ENERGY STAR score of 75 or higher.

4. Licensed Professional Verification

ENERGY STAR certification requires verification by a licensed Professional Engineer (PE) or Registered Architect (RA).

IE Energy coordinates the required professional verification and documentation.

5. Certification Application Submission

We prepare and submit the ENERGY STAR certification application through Portfolio Manager and coordinate the review process with the EPA.

ENERGY STAR Certification vs Energy Benchmarking

Energy benchmarking and ENERGY STAR certification are closely related but serve different purposes.

Energy Benchmarking tracks and reports building energy consumption annually.

ENERGY STAR Certification recognizes buildings that perform in the top 25% of similar buildings for energy efficiency.

Benchmarking is often the first step toward achieving certification.
