Offering required Rescheck and Manual J Report certifications and other energy code compliance reports to obtain your building permit in all 50 States!  One of our main affiliates, Rescheck Review is our provider of quality, affordable rescheck reports for architects, builders, and homeowners.



A Rescheck determines whether new homes, additions, and alterations meet the requirements of the IECC or the National Energy Code. Rescheck also simplifies compliance determinations for building officials, plan checkers, and inspectors by allowing them to quickly determine if a low-rise residence meets the code.

Rescheck is appropriate for insulation and window trade-off calculations in residential-detached one and two-story family buildings and multi-family buildings three stories or less in height above grade, such as apartments, condominiums, and townhouses.

Rescheck works by performing a simple U-factor x Area (UA) calculation for each building assembly to determine the overall UA of a building. The UA that would result from a building conforming to the code requirements is compared against the UA for your building. If the total heat loss (represented as a UA) through the envelope of your building does not exceed the total heat loss from the same building conforming to the code, the software generates a report that declares your building is compliant with the code.

What is a Rescheck UA tradeoff?

The UA alternative, commonly known as ResCheck path, also converts everything to a U-value but because it is the sum of u-factor times assembly area, it will allow trade-offs between other items that may be converted to a U-value, as long as the total UA is less than or equal to a prescriptive house (U= 1/R).

Manual J?

Created by the Air Conditioning Contractors of America (ACCA), “Manual J8 Residential Load Calculation” or “Manual J” for short, is a tool that provides detailed requirements for producing residential load calculations for single-family residential homes. Those load calculations are then used to get the correct size of heating and cooling equipment into the home.


Window measurements, insulation, roof design, local climate, and many more factors are used to determine the HVAC equipment needed to condition interior spaces without wasting energy.
