Preparing a REScheck Report is one method for validating compliance with the IECC Building Code (International Energy Compliance Code). This report can be performed on new construction homes, remodels or additions. The REScheck calculation method allows a designer or builder to consider trade-offs of building material specifications, such as insulation and window specs, giving an alternate path to compliance and not having to meet every specification required by the prescriptive tables. This results in greater flexibility on a project – when one component far exceeds minimum requirements, a builder can reduce specifications on other items.
Here are a few examples of a need for a RESCheck Report:
As a builder you may have the desire to maintain 2×4 framing on above grade walls; the use of larger windows that can’t meet the minimum U-factor requirements; or the need to provide alternate solutions for areas that can’t achieve the minimum insulation requirements without costly foam insulation. Under scenarios like this, performing a REScheck calculation is a way to show compliance with the IECC while maintaining the desired window or insulation values.

So how does it work?
The REScheck software performs a ‘U-factor’ x ‘Area’ (UA) calculation on each assembly entered. The total building UA is then calculated and compared within the software to an identical building that just meets basic code levels. If the building being analyzed has a lower total heat loss calculation, as compared to the code minimum house, then compliance is achieved.
A report is prepared that is submitted with your other permit documents, validating compliance. In Colorado, each local municipality is on a different code level, and some have unique amendments that need to be met. Working with an energy-efficiency and IECC specialist is helpful to ensure you meet the required compliance for your area.
