Formerly known as the Home Energy Rating System (HERS), the updated Energy Code Compliance (ECC) Program is a required compliance process used to verify that building systems meet California Energy Code, Title-24, Part 6, standards. As ECC-Raters, we verify and test new construction, alterations, and additions across residential and nonresidential development.

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. 

Air Balancing involves testing, adjusting, and balancing the distribution of air to the designated zones by an HVAC system. An efficient, balanced HVAC system maintains comfort, reliability, and air quality. Whether it is an office space, residential or commercial kitchen, or schools gymnasium — air balance testing is absolutely necessary to ensure optimal comfort and energy efficiency. We perform comprehensive airflow diagnostics using industry-standard instruments to ensure systems operate efficiently, safely, and in compliance with design specifications.

Specific certifications such as LEED, ENERGY STAR, and GreenPoint Rated recognize a building’s commitment to energy efficiency, sustainability, and healthy qualities. Achieving these certifications require meeting specific standards and performance ratings that our teams are certified and experienced to provide.

Acceptance testing often encompasses the verification of a building system’s installation, functionality, and performance. Verifying a system ensures that it’s performing as designed and as required under California’s Energy Code. Our certified technicians are skilled in conducting Mechanical and Lighting Controls Acceptance Testing for various building types such as multifamily, commercial warehouses, and office spaces.

Large compartmentalization testing, also known as whole-building blower door testing or building enclosure leakage testing, is a specialized diagnostic process used to evaluate the airtightness and integrity of large commercial, industrial, and multifamily structures. The purpose of this testing is to measure uncontrolled air leakage through the building envelope, helping owners, developers, and contractors identify deficiencies that may impact energy efficiency, indoor environmental quality, occupant comfort, moisture control, and long-term building performance.

Outside of California, other states use the Home Energy Rating System (HERS) Index Score, a national standard system by which a home’s energy performance is evaluated. HERS Ratings verify the energy performance of a new home to ensure it meets the minimum national standard. As certified RESNET Raters, we are qualified to perform HERS Ratings nationally in every state for new construction, alterations, and additions across residential and nonresidential development.
