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.
All inspections are documented and compiled into compliance reports suitable for:
- Building department approvals
- HERS rating submissions
- Energy Audits
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
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
It’s Not Just for Compliance !!
