Beyond Blower Door & Duct Testing
In addition to blower door and duct leakage testing, the International Energy Conservation Code (IECC) requires several other verification measures to ensure a building meets energy efficiency standards. At Assured Building Compliance (ABC), we provide comprehensive field inspections and performance testing to support full IECC compliance.
Other Testing Services
Mechanical Ventilation Verification:
Proper ventilation is critical for indoor air quality and energy performance. We verify that mechanical ventilation systems are:
- Installed according to design specifications
- Delivering required airflow rates per code
- Properly balanced and operational
This ensures compliance with IECC and standards such as ASHRAE 62.2.
Air Barrier & Insulation Inspection:
Before drywall installation, we perform detailed inspections of the building envelope to confirm:
- Continuous air barrier alignment
- Proper insulation installation (Grade I or II where required)
- Sealing of penetrations, joints, and transitions
This step is essential to prevent energy loss and avoid costly corrections later.
Fenestration & Envelope Compliance:
We verify that all windows, doors, and skylights meet IECC requirements, including:
- U-factor and SHGC ratings
- Proper labeling and installation
- Compliance with approved plans and energy calculations
Lighting & Electrical Efficiency Verification:
For residential and commercial projects, we inspect lighting systems to ensure:
- High-efficacy lighting requirements are met
- Controls (timers, dimmers, occupancy sensors) are installed where required
Thermostat & Controls Verification:
We confirm that programmable or smart thermostats are:
- Installed per IECC requirements
- Properly configured for energy-saving operation
Equipment Efficiency Verification:
We review installed HVAC and water heating equipment to ensure:
- Minimum efficiency ratings meet IECC standards
- Equipment matches approved submittals and energy models
- Documentation & Compliance Reporting
All inspections are documented and compiled into a compliance report suitable for:
- Building department approvals
- HERS rating submissions
- Energy Audits
It’s Not Just for Compliance !!
IECC compliance is not just about passing inspections—it ensures:
- Lower energy bills
- Improved occupant comfort
- Reduced environmental impact
- Faster project approvals
- Building durability
- Increased resale values
