Custom-home ECC Verifications
Formerly known in California as the Home Energy Rating System (HERS), the Energy Code Compliance (ECC) Program is a required compliance process used to verify that building systems—such as ducts, HVAC, and insulation—meet California Energy Code (Title-24, Part 6) standards. As certified ECC-Raters, we verify and test custom-built single-family homes throughout Southern California.
We specialize in the following ECC Verifications and Tests:
- Duct Leakage Testing: Measures air leakage in the duct system to verify compliance with California Energy Code requirements and ensure efficient HVAC performance.
- Whole-House Ventilation / Indoor Air Quality (IAQ): Verifies that mechanical ventilation systems provide the required outdoor air rates to support healthy indoor air quality.
- High-performance Attic/Wall Inspections: Inspects building envelope assemblies to confirm proper installation of insulation, air barriers, and energy-efficiency measures.
- Refrigerant Charge & Airflow Verification: Confirms that HVAC systems have the correct refrigerant charge and airflow to operate efficiently and as designed.
- Fan Watt Draw/Efficacy: Measures HVAC fan energy consumption and airflow performance
- Existing Conditions Documentation: Documents existing building, mechanical, and energy-related conditions to support alterations, retrofits, and code compliance verification.
- Quality Insulation Installation (QII): Verifies that insulation is installed to industry standards with proper alignment, coverage, and minimal gaps or compression.
- Domestic Hot Water System Verification: Confirms that water heating systems, piping, and other components meet applicable energy code requirements.
- Compartmentalization Blower Door Testing (Multifamily and Commercial): Measures air leakage between units and building compartments to verify energy efficiency and enclosure performance.
- CF-3R Compliance Documentation via CHEERS: Submission of certified third-party verification and registration of required energy compliance measures through the CHEERS registry.
As an approved Whole-House ECC-Rater for projects aiming to achieve beyond the CA Energy Code, we can verify and consult projects to achieve performance-based ratings and certifications such as Energy Star, Zero Net Energy, LEED for Homes, GreenPoint Rating, and CalGreen.
Our Expertise in Custom Single-family Homes
Our ECC verifications for custom single-family homes have been the backbone of our reputation in our communities since our founding. Whether the home is a luxury estate, tract home, or townhome, our verifications and tests are tailored to each home to ensure optimal compliance and performance. From insulation to move-in ready, we’ll support a new home through every stage of development. After conducting our field tests, we’ll handle the reports and certifications with the agency registries directly.
