Code Compliance Performance Alternative (N1105) - This is a North Carolina performance-based compliance option that can save your project when traditional code compliance fails. Available throughout the Triangle area and all NC jurisdictions.

It evaluates whether a home meets energy requirements by comparing the simulated energy cost of the proposed (as-built) home to that of a standard code-compliant home.

How It Works

If the simulation shows that the as-built home uses the same amount or less energy than the code-built model, you will pass inspection.

If you have failed a code inspection and cannot move on in your building process, this alternative pathway can potentially allow you to continue to move forward. We also offer comprehensive energy efficiency consulting and blower door testing services to help prevent compliance issues.

What information do you need to get started? We need your building plans, HVAC specifications, insulation details, window schedules, and any failed inspection documentation.

Is this accepted by all North Carolina jurisdictions? Yes, the N1105 Performance Alternative is a state-approved compliance path accepted by all NC building departments.

What’s the cost compared to making physical changes? The Performance Alternative analysis typically costs significantly less than retrofitting insulation, windows, or HVAC systems to meet prescriptive code requirements.

Do you serve the entire Triangle area? Yes, we provide N1105 Performance Alternative services throughout North Carolina, with frequent projects in Raleigh, Durham, Chapel Hill, and surrounding communities.
