What are some parts of the IECC 2021 Inspection?

The International Energy Conservation Code (IECC) is a set of building energy efficiency standards published by the International Code Council (ICC). The IECC 2021 includes requirements for building envelope, mechanical systems, lighting, and other aspects of energy use in buildings. An inspection of a building constructed to meet the IECC 2021 would typically involve verifying compliance with various requirements. Some key parts of the inspection might include:

1) Building Envelope Inspection: This involves assessing components such as insulation, air barriers, windows, doors, and overall construction to ensure they meet the specified thermal performance requirements. Inspectors would check for proper insulation installation, effective air sealing, and compliance with fenestration (window and door) requirements.

2) Ductwork Inspection: Inspectors would verify that ductwork systems are properly installed and sealed according to the IECC requirements. This includes checking for tight connections, insulation where required, and compliance with duct leakage limits.

3) HVAC System Inspection: This involves evaluating the efficiency and proper installation of heating, ventilation, and air conditioning (HVAC) systems. Inspectors would assess equipment sizing, duct design, system controls, and compliance with efficiency standards such as SEER (Seasonal Energy Efficiency Ratio) for air conditioners and AFUE (Annual Fuel Utilization Efficiency) for furnaces.

4) Lighting Inspection: Inspectors would verify compliance with lighting efficiency requirements, such as maximum power allowances for lighting fixtures, use of energy-efficient lamps, and compliance with lighting control requirements for certain spaces.

5) Building Performance Testing: Depending on local requirements and the specifics of the building, various performance tests might be conducted, such as blower door testing for air leakage, duct blaster testing for ductwork leakage, or thermal imaging to identify insulation defects.

6) Documentation Review: Inspectors would review documentation, such as building plans, product specifications, and installation records, to ensure compliance with IECC requirements.

7) Code Compliance Verification: Overall, the inspection process involves verifying that the construction meets the specific requirements of the IECC 2021 edition as adopted by the relevant jurisdiction. This includes ensuring compliance with applicable sections related to energy efficiency, insulation, air sealing, mechanical systems, lighting, and other aspects of building energy use.
