Pasadena ECC Testing & HERS Services
Streamlining Your Path to Efficiency, Compliance, & Occupancy
Navigating the modern building landscape requires a deep understanding of the Energy Code Compliance (ECC) Program. This regulatory framework ensures that new and altered buildings meet specific energy efficiency standards before they can be legally occupied. Our team provides the essential ECC testing service required by the City of Pasadena. We act as objective third-party verifiers, conducting the necessary field diagnostic tests to prove that your construction aligns perfectly with the energy design calculations submitted during the plan check process.
Assessing Energy Efficiency Our certified raters utilize the Energy Rating Index and verified ECC methodologies to strictly evaluate your property’s performance. We provide a precise numerical score that rates a building’s energy efficiency. This ECC rating functions similarly to a miles-per-gallon sticker for a vehicle; a lower score indicates a higher level of efficiency. In Pasadena’s high-value real estate market, a verified low energy score is a proven asset, signaling a home that respects its history while performing with modern resilience and comfort.
Residential Solutions: Historic & Modern Harmony For homeowners in Pasadena, our HERS testing service is designed to identify invisible energy drains without compromising architectural integrity. We tailor our testing to the unique challenges of the city’s diverse housing stock.
- Duct Leakage Testing: In Pasadena’s historic Craftsman and Spanish Colonial homes, original ductwork is often wrapped in asbestos or routed through tight crawlspaces. We verify that new, safe ductwork is sealed tight, ensuring that your upgraded HVAC system efficiently conditions the home without pressurizing historic plaster walls.
- Refrigerant Charge Verification: We ensure your air conditioner meets the manufacturer’s precise specifications. A correct charge is critical for efficiency and longevity, helping you manage cooling costs during Pasadena’s famously hot summers.
- Indoor Air Quality (IAQ): We verify that bathroom fans and kitchen range hoods meet ASHRAE standards for airflow. This is particularly important for renovations in historic districts where windows may be original and inoperable or sealed for preservation, making mechanical ventilation essential for health.
- Quality Insulation Installation (QII): We inspect insulation at the framing stage to ensure there are no gaps or voids. This is often a mandatory requirement for new ADUs and room additions to meet Title 24 compliance standards while keeping the structure comfortable.
Commercial Verification: Serving Science & Commerce We offer a full suite of commercial services to support general contractors and facility managers in Pasadena’s world-class business and science sectors.
- Commercial Air Balancing: We perform precise air balancing to ensure every register in a research lab, lecture hall, or retail boutique delivers the correct volume of air. This optimizes the comfort of occupants while ensuring the HVAC system operates efficiently under the strict load demands often found in tech and science facilities.
- Mechanical Acceptance Testing: Our technicians verify that complex systems like economizers, variable frequency drives (VFDs), and demand-control ventilation operate as designed. This satisfies the rigorous non-residential Title 24 requirements enforced by the city, particularly for retrofits in Old Pasadena where energy efficiency is key to modernizing historic structures.
- System Performance Evaluation: We conduct audits of existing HVAC systems to identify inefficiencies, helping businesses reduce overhead costs and meet corporate sustainability targets in Pasadena’s competitive commercial market.
Promoting Sustainable Building Practices Our testing services are a fundamental component of Pasadena’s aggressive Climate Action Plan. A verified home energy score encourages the construction of buildings that consume significantly less energy, thereby reducing carbon footprints. By validating that high-performance systems—such as high-efficiency heat pumps, EV charger readiness, and solar arrays—are installed correctly, we ensure your building contributes to the city’s renowned legacy of innovation and sustainability.
Incentives and Rebates Achieving high performance through ECC testing is financially rewarding. Pasadena Water and Power (PWP) offers some of the most generous rebates in the region for energy-efficient upgrades. A professional HERS rating in Pasadena is often the mandatory documentation required to claim these valuable financial incentives for upgrades like high-performance windows, cool roofs, and electric heat pumps. We assist you in gathering the necessary data to maximize your return on investment from your municipal utility.

Common Questions About Energy Compliance
What is the Energy Code Compliance (ECC) Program? The ECC Program refers to the comprehensive set of standards (Title 24) designed to reduce energy consumption in buildings. It mandates independent verification by a certified ECC testing service to ensure that installed energy features meet the approved energy design.
Do you verify systems for historic homes in Bungalow Heaven? Yes. We have extensive experience working within Pasadena’s designated Landmark Districts. We can verify modern HVAC upgrades while understanding the sensitivity required for preservation projects, ensuring compliance without damaging the home’s historic character.
What is the difference between HERS testing and ECC testing? These terms are often used interchangeably as the industry transitions its terminology. HERS (Home Energy Rating System) is the legacy term, while ECC testing refers to the broader verification activities required to meet the modern Energy Code Compliance Program standards. Our company is certified to perform both.
Why is an ECC rating important in Pasadena? An ECC rating or HERS rating is typically required by the Pasadena Building & Safety Division to finalize a building permit. It serves as proof that the home’s energy features were installed correctly and perform as promised, ensuring the issuance of your Certificate of Occupancy.
Are you insured? Yes, Home Energy Rating Service is fully licensed, bonded, and insured. We carry comprehensive liability insurance ($1M) to protect our clients and their properties during all inspections and testing procedures.
